HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.
When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding of connection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

Engine Control for 2UZ-FE (Access/Standard Cab)
The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof the engine control is given here.
1. Input Signals(1) Engine coolant temp. signal circuit
The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.
(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B, OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal isinput into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA1, VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor, detects the vehicle speed and input to the speed sensor of the skid control ECU withactuator, from skid control ECU to TERMINAL SPD of the engine control module, via combination meter.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B, +B2 of theengine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, andvoltage is constantly applied to TERMINAL +BM.
(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine controlmodule as a control signal.
System Outline

2. Control System∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50, #60, #70, #80 to operate theinjector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the drivingconditions.
∗ ESA systemThe ESA system monitors the engine condition through the signals input from each sensors to the engine control module.The best ignition timing is decided according to this data and the data memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control theigniter to provide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINALS HT1B and HT2B to control theheater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low) and warms up the air fuel ratio sensor to improve detection performance of the sensor. The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2Acontrolling the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump withthe F/PMP relay.
∗ ETCS-iThe ETCS-i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail-Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail-safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof the engine control is given here.
1. Input Signals(1) Engine coolant temp. signal circuit
The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.
(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B, OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal isinput into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA1, VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor, detects the vehicle speed and input to the speed sensor of the skid control ECU withactuator, from skid control ECU to TERMINAL SPD of the engine control module, via combination meter.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B, +B2 of theengine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, andvoltage is constantly applied to TERMINAL +BM.
(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine controlmodule as a control signal.

Engine Control for 1GR-FE (Access/Standard Cab)
2. Control System∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50, #60 to operate the injector(Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the drivingconditions.
∗ ESA systemThe ESA system monitors the engine condition through the signals input from each sensors to the engine control module.The best ignition timing is decided according to this data and the data memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6 and these signals control the igniter to providethe best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINALS HT1B and HT2B to control theheater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low) and warms up the air fuel ratio sensor to improve detection performance of the sensor. The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2Acontrolling the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump withthe F/PMP relay.
∗ ETCS-iThe ETCS-i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail-Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail-safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

With the ignition SW turned on, the current flows to TERMINAL 9 of the integration relay through ECU IG fuse.Voltage is applied at all times to TERMINAL 6 of the integration relay through the TAIL fuse, and through the H-LP relay coilside.
1. Normal Lighting Operation<Turn taillight on>With the light control SW turned to TAIL position, a signal is input into the integration relay. Due to this signal, the currentflowing to TERMINAL 6 of the relay flows to TERMINAL 14 of the light control SW to TERMINAL 16 to GROUND, andtaillights to turn on.
<Turn headlight on>With the light control SW turned to HEAD position, a signal is input into the integration relay. Due to this signal, the currentflowing to the relay flows to TERMINAL 13 of the light control SW to TERMINAL 16 to GROUND in the headlight circuit, andcauses taillight and H-LP relay to turn the lights on. The taillight circuit is same as above.
2. Light Auto Turn Off OperationWith light on and ignition SW turned off (Input signal goes to TERMINAL 9 of the relay), when the driver’s door is opened(Input signal goes to TERMINAL 14 of the relay), the relay operates and the current is cut off which flows from TERMINAL 6and through the H-LP relay coil side of the relay to taillight circuit and headlight circuit.As a result, all lights are turned off automatically.

The electronically controlled transmission electrically controls the, throttle pressure, lock-up pressure, and accumulatorpressure etc. through the solenoid valve.The electronically controlled transmission is a system which precisely controls the gear shift timing and lock-up timing inresponse to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth drivingpossible by shift selection of the gear which is the most appropriate to the driving conditions at that time, and by preventingdowning, squat and gear shift shock when starting off.
1. Gear Shift OperationWhen driving, the engine warm up condition is input as a control signal from the engine coolant temp. sensor to TERMINALTHW of the engine control module, and the vehicle speed is input to TERMINAL SP2+ of the engine control module from thevehicle speed sensor. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA1, VTA2 of the engine control module as a throttle angle signal. Based on these signals, the engine controlmodule selects the best shift position for the driving conditions and sends current to the electronically controlled transmissionsolenoid.
2. Lock-Up OperationWhen the engine control module decides based on each signal that the lock-up condition has been met, the current flowsthrough TERMINAL SLU+ of the engine control module to TERMINAL 5 of the electronically controlled transmission solenoidto TERMINAL 13 to TERMINAL SLU- of the engine control module to GROUND.
3. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock-up position, a signal is input to TERMINAL STP ofthe engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock-up.
4. Overdrive Circuit∗ O/D main SW on
When the O/D main SW is switched to ON position, a signal is input to TERMINAL ODMS of the engine control module,and enables shift change to the overdrive range, through the control of the engine control module.
∗ O/D main SW offWhen the O/D main SW is switched to OFF position, a signal is input to TERMINAL ODMS of the engine control module,and prohibits shift change to the overdrive range through the control of the engine control module. When in the overdriverange already, shift down is made.

The electronically controlled transmission electrically controls the, throttle pressure, lock-up pressure, and accumulatorpressure etc. through the solenoid valve.The electronically controlled transmission is a system which precisely controls the gear shift timing and lock-up timing inresponse to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth drivingpossible by shift selection of the gear which is the most appropriate to the driving conditions at that time, and by preventingdowning, squat and gear shift shock when starting off.
1. Gear Shift OperationWhen driving, the engine warm up condition is input as a control signal from the engine coolant temp. sensor to TERMINALTHW of the engine control module, and the vehicle speed is input to TERMINAL SP2+ of the engine control module from thevehicle speed sensor. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA1, VTA2 of the engine control module as a throttle angle signal. Based on these signals, the engine controlmodule selects the best shift position for the driving conditions and sends current to the electronically controlled transmissionsolenoid.
2. Lock-Up OperationWhen the engine control module decides based on each signal that the lock-up condition has been met, the current flowsthrough TERMINAL SLU+ of the engine control module to TERMINAL 5 of the electronically controlled transmission solenoidto TERMINAL 13 to TERMINAL SLU- of the engine control module to GROUND.
3. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock-up position, a signal is input to TERMINAL STP ofthe engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock-up.
4. Overdrive Circuit∗ O/D main SW on
When the O/D main SW is switched to ON position, a signal is input to TERMINAL ODMS of the engine control module,and enables shift change to the overdrive range, through the control of the engine control module.
∗ O/D main SW offWhen the O/D main SW is switched to OFF position, a signal is input to TERMINAL ODMS of the engine control module,and prohibits shift change to the overdrive range through the control of the engine control module. When in the overdriverange already, shift down is made.

1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the fourwheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedalis depressed suddenly, the skid control ECU controls the solenoids in the actuators using the signals from the sensors tomove the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the skid controlECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators toincrease the braking pressure.
2. Traction Control OperationThe traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of thewheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stabilitycorresponding to the road conditions.
3. VSC OperationUnexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- orover-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes toreduce the under- or over-steering.To reduce large over-steering :If the VSC system determines that the over-steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the over-steering.To reduce large under-steering :If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheelbrakes to reduce the under-steering.Traction control SWThe traction control SW is used to stop the TRAC function. After the engine is started, the TRAC system is stopped (turnedoff) and the VSC OFF indicator light lights up. When the traction control SW is pressed again, the TRAC system enters thestand-by mode. If the engine is stopped and restarted, the TRAC system enters the stand-by mode regardless of thetraction control SW.
4. Mutual System ControlTo efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlledwhile the VSC system is being operated.Engine throttle controlThe engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing theengine output.Engine control and electronically controlled transmission controlThe strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. andreducing changes in the driving torque at shift-down.VSC system operation indicationThe Slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whilethe VSC system is being operated.
5. Fail Safe FunctionIf an error occurs in the skid control ECU with actuator, sensor signals, and/or actuators, the skid control ECU with actuatorinhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal, thebrake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open requestfrom the VSC system. As a result, the vehicle functions regardless of the ABS, TRAC, and VSC systems.

ABS (Access/Standard Cab)
This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left frontwheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.This results in improved directional stability and steerability during panic braking.
1. Input Signal(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS actuator with ECU.(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS actuator with ECU when the brake pedal is depressed.
2. System OperationDuring sudden braking, the ABS actuator with ECU which has signals input from each sensor lets the hydraulic pressureacting on each wheel cylinder escape to the reservoir.The pump inside the ABS actuator with ECU is also operating at this time and it returns the brake fluid from the reservoir tothe master cylinder, thus preventing locking of vehicle wheels.If the ABS actuator with ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current actingon the solenoid is controlled and the hydraulic pressure is increased.Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressurereduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

Cruise Control for 2UZ-FE (Access/Standard Cab)
The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valveby the SW, and allows driving at a constant speed without depressing the accelerator pedal.
1. Set ControlWhen the - SET SW is operated while traveling with the ON-OFF SW on, the speed when the - SET SW is operated to offis memorized, and the vehicle speed is controlled at that speed.
2. Coast ControlWhen the - SET SW is operated to on, the cruise control opening angle requirement is turned to 0 to decrease the vehiclespeed, and the speed when the - SET SW is operated to off is memorized, and the vehicle speed is controlled at that speed.Furthermore, every time the - SET SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isdecreased by approx. 1.6 km/h (1.0 mph).
3. Accel ControlWhen the + RES SW is operated to on, the throttle motor rotates the throttle valve to open direction to increase the vehiclespeed, and the speed when the + RES SW is operated to off is memorized, and the vehicle speed is controlled at thatspeed.Furthermore, every time the + RES SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isincreased by approx. 1.6 km/h (1.0 mph).
4. Manual Cancel MechanismIf any of the following signals are input during cruise control traveling, the current to the motor flows in the direction to closethe throttle valve, and cancel the cruise control.(1) Stop lamp SW is on (Brake pedal is depressed)
(2) The CANCEL SW of the control SW is on
(3) ON-OFF SW is off
(4) Gear is shifted from D position to other positions than D.
5. Resume ControlAfter canceling the cruise control (Except when the ON-OFF SW is off) if the vehicle speed is above the minimum speedlimit (Approx. 40km/h, 25mph), operating the + RES SW to on from off will cause the system to accelerate and resume to thevehicle speed before manual cancellation.
6. Overdrive FunctionThe overdrive may be cut on an uphill grade, while traveling with the cruise control.After the overdrive is cut, when the throttle opening information indicates the hill climbing is finished after the overdrive iscanceled, the vehicle returns to overdrive mode again as the overdrive return timer is completed, and if the systemdetermines that the uphill grade has finished, the overdrive will resume after the overdrive timer operation.
7. Auto Cancel OperationIf any of the following conditions are detected, the control is canceled.(1) Disconnection and/or short in the stop light SW
(2) Malfunction in the vehicle speed signal
(3) Malfunction in the electronic throttle parts
(4) Malfunction in the stop light SW input circuit
(5) Malfunction in the cancel circuit
(6) When the vehicle speed gets slower than the low speed limit.
(7) The actual vehicle speed becomes -16 km/h (10 mph) slower than the set speed

Cruise Control for 1GR-FE (Access/Standard Cab)
The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valveby the SW, and allows driving at a constant speed without depressing the accelerator pedal.
1. Set ControlWhen the - SET SW is operated while traveling with the ON-OFF SW on, the speed when the - SET SW is operated to offis memorized, and the vehicle speed is controlled at that speed.
2. Coast ControlWhen the - SET SW is operated to on, the cruise control opening angle requirement is turned to 0 to decrease the vehiclespeed, and the speed when the - SET SW is operated to off is memorized, and the vehicle speed is controlled at that speed.Furthermore, every time the - SET SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isdecreased by approx. 1.6 km/h (1.0 mph).
3. Accel ControlWhen the + RES SW is operated to on, the throttle motor rotates the throttle valve to open direction to increase the vehiclespeed, and the speed when the + RES SW is operated to off is memorized, and the vehicle speed is controlled at thatspeed.Furthermore, every time the + RES SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isincreased by approx. 1.6 km/h (1.0 mph).
4. Manual Cancel MechanismIf any of the following signals are input during cruise control traveling, the current to the motor flows in the direction to closethe throttle valve, and cancel the cruise control.(1) Stop lamp SW is on (Brake pedal is depressed)
(2) The CANCEL SW of the control SW is on
(3) ON-OFF SW is off
(4) Gear is shifted from D position to other positions than D.
5. Resume ControlAfter canceling the cruise control (Except when the ON-OFF SW is off) if the vehicle speed is above the minimum speedlimit (Approx. 40km/h, 25mph), operating the + RES SW to on from off will cause the system to accelerate and resume to thevehicle speed before manual cancellation.
6. Overdrive FunctionThe overdrive may be cut on an uphill grade, while traveling with the cruise control.After the overdrive is cut, when the throttle opening information indicates the hill climbing is finished after the overdrive iscanceled, the vehicle returns to overdrive mode again as the overdrive return timer is completed, and if the systemdetermines that the uphill grade has finished, the overdrive will resume after the overdrive timer operation.
7. Auto Cancel OperationIf any of the following conditions are detected, the control is canceled.(1) Disconnection and/or short in the stop light SW
(2) Malfunction in the vehicle speed signal
(3) Malfunction in the electronic throttle parts
(4) Malfunction in the stop light SW input circuit
(5) Malfunction in the cancel circuit
(6) When the vehicle speed gets slower than the low speed limit.
(7) The actual vehicle speed becomes -16 km/h (10 mph) slower than the set speed

SRS (Access/Standard Cab)
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and thenegative (-) terminal cable is disconnected from the battery.(The SRS is equipped with a back-up power source so that if work is started within 90 seconds fromdisconnecting the negative (-) terminal cable of the battery, the SRS may deploy.)
When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back-up power supply from outside the vehicle.
Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
Do not expose the following parts directly to hot air or flame;
Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
For the purpose of reuse, never disassemble and repair the following parts.
If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.
Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
After work on the SRS is completed, check the SRS warning light.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

The SRS is a driver protection device which has a supplemental role to the seat belts.When the ignition SW on, the current from the IGN fuse flows to TERMINAL (A) 21 of the center airbag sensor assembly.If an accident occurs while driving, deceleration caused by a frontal impact is detected (by sensor) and when the frontalimpact exceeds a set level, the current from the IGN fuse flows to TERMINAL (A) 21 of the center airbag sensor assembly.This current flows to TERMINALS (A) 4, (A) 5, (B) 2, (C) 4 to TERMINAL 1 of the airbag squib (Steering wheel pad) andpretensioners to TERMINAL 2 to TERMINALS (A) 3, (A) 6, (B) 1, (C) 5 of the center airbag sensor assembly to TERMINAL(B) 27 or (B) 28 to GROUND, causing the center airbag squibs to expand.When the safing sensor built into the center airbag sensor assembly is on, airbag sensor is off and the current from the IGNfuse flows same as above-mentioned flowing, causing the airbag squibs to expand. When the safing sensor built into thecenter airbag sensor assembly is on, the airbag sensor on one of the above-mentioned circuits is activated so that currentflows to the airbag squibs and causes them to operate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to thepassenger.
Front Passenger Airbag On/Off OperationWhen the passenger airbag manual On-Off SW is on, the current flowing from the IGN fuse to the airbag squib (Frontpassenger airbag assembly) is same as above, causing the airbag squib (Front passenger airbag assembly) to expand in anaccident.

Current always flows to TERMINAL 3 of the integration relay through the POWER fuse.
1. Manual Lock Operation(Driver’s door)To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integrationrelay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of thedoor lock motor to TERMINAL 3 to TERMINAL 2 of the TVIP ECU to TERMINAL 4 to TERMINAL 12 of the integration relayto TERMINAL 8 to GROUND and the door lock motor causes the door to lock.(Passenger’s door)To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integrationrelay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of thedoor lock motor to TERMINAL 3 to TERMINAL 12 of the relay to TERMINAL 8 to GROUND and the door lock motor causesthe door to lock.
2. Manual Unlock Operation(Driver’s door)To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to theintegration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 toTERMINAL 4 of the TVIP ECU to TERMINAL 2 to TERMINAL 3 of the door lock motor to TERMINAL 2 to TERMINAL 13 ofthe integration relay to TERMINAL 8 to GROUND and the door lock motor causes the door to unlock.(Passenger’s door)To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to theintegration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 toTERMINAL 3 of the door lock motor to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and the doorlock motor causes the door to unlock.
3. Double Operation Unlock OperationWhen the door key lock and unlock SW LH is turned to unlock position, only the front LH door is mechanically unlocked.Turning the door key lock and unlock SW LH to the unlock side causes a signal to be input to the relay, and if the signal isinput again within 3 seconds by turning the door key lock and unlock SW LH to the unlock side again, current flows fromTERMINAL 12 of the integration relay to TERMINAL 4 of the TVIP ECU to TERMINAL 2 to TERMINAL 3 of the door lockmotor, TERMINAL 2 to TERMINAL 13 of the integration relay to TERMINAL 8 to GROUND, causing the door lock motors tooperate and unlock the doors.
4. Key Confine Prevention Function∗ Operating door lock knob (In door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using door lock knob (Doorlock motor), the door is locked once but each door is unlocked soon by the function of the integration relay. As a result,current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 toTERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.
∗ Operating door lock control SW or door key lock and unlock SWWith ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using the door lock controlSW or door key lock and unlock SW, all doors are locked once but each door is unlocked by the function of the SWcontained in motor, which inputs the signal to the integration relay. According to this input signal, current flows fromTERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 ofthe relay to TERMINAL 8 to GROUND and causes all the doors to unlock.

Current always flows to TERMINAL 3 of the integration relay through the POWER fuse.
1. Manual Lock Operation(Driver’s door)To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integrationrelay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of thedoor lock motor to TERMINAL 3 to TERMINAL 2 of the TVIP ECU to TERMINAL 4 to TERMINAL 12 of the integration relayto TERMINAL 8 to GROUND and the door lock motor causes the door to lock.(Passenger’s door)To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integrationrelay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of thedoor lock motor to TERMINAL 3 to TERMINAL 12 of the relay to TERMINAL 8 to GROUND and the door lock motor causesthe door to lock.
2. Manual Unlock Operation(Driver’s door)To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to theintegration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 toTERMINAL 4 of the TVIP ECU to TERMINAL 2 to TERMINAL 3 of the door lock motor to TERMINAL 2 to TERMINAL 13 ofthe integration relay to TERMINAL 8 to GROUND and the door lock motor causes the door to unlock.(Passenger’s door)To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to theintegration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 toTERMINAL 3 of the door lock motor to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and the doorlock motor causes the door to unlock.
3. Double Operation Unlock OperationWhen the door key lock and unlock SW LH is turned to unlock position, only the front LH door is mechanically unlocked.Turning the door key lock and unlock SW LH to the unlock side causes a signal to be input to the relay, and if the signal isinput again within 3 seconds by turning the door key lock and unlock SW LH to the unlock side again, current flows fromTERMINAL 12 of the integration relay to TERMINAL 4 of the TVIP ECU to TERMINAL 2 to TERMINAL 3 of the door lockmotor, TERMINAL 2 to TERMINAL 13 of the integration relay to TERMINAL 8 to GROUND, causing the door lock motors tooperate and unlock the doors.
4. Key Confine Prevention Function∗ Operating door lock knob (In door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using door lock knob (Doorlock motor), the door is locked once but each door is unlocked soon by the function of the integration relay. As a result,current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 toTERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.
∗ Operating door lock control SW or door key lock and unlock SWWith ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using the door lock controlSW or door key lock and unlock SW, all doors are locked once but each door is unlocked by the function of the SWcontained in motor, which inputs the signal to the integration relay. According to this input signal, current flows fromTERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 ofthe relay to TERMINAL 8 to GROUND and causes all the doors to unlock.

Power Window (Access/Standard Cab)
With the ignition SW turned on, current flows through the ECU IG fuse to TERMINAL 9 of the integration relay to TERMINAL2 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND, activating the power relay, and the current flowing fromTERMINAL 5 of the power relay flows to TERMINAL 3 to TERMINAL 9 of the power window master SW, TERMINAL 4 of thepower window control SW RH and TERMINAL 1 of power window SW (Back window).
1. Manual Operation (Driver’s Window)With the ignition SW turned on and with the power window master SW (Manual SW) in UP position, the current flowing toTERMINAL 9 of the power window master SW flows to TERMINAL 3 to TERMINAL 2 of the power window motor LH toTERMINAL 1 to TERMINAL 4 of the master SW to TERMINAL 1 to GROUND and causes the power window motor to rotatein the up direction. The window ascends only while the SW is being pushed.In down operation, the current flowing from TERMINAL 9 of the power window master SW to TERMINAL 4 flows toTERMINAL 1 of the motor LH to TERMINAL 2 to TERMINAL 3 of the master SW to TERMINAL 1 to GROUND, flowing in theopposite direction to manual up operation, causing the motor to rotate in reverse and lowering the window.
2. Auto Down Operation (Driver’s Window)With the ignition SW on and with the auto SW of the power window master SW in DOWN position, the current flowing toTERMINAL 9 of the master SW flows to TERMINAL 4 of the master SW to TERMINAL 1 of the power window motor LH toTERMINAL 2 to TERMINAL 3 of the master SW to TERMINAL 1 to GROUND, causing the motor to rotate towards the downside.Then the solenoid in the master SW is activated and it locks the auto SW being pushed, causing the motor to continue torotate in auto down operation.When the window has completely descended, the current flowing between TERMINAL 3 of the master SW and TERMINAL 1increases. As a result, the solenoid stops operating, the auto SW turns off and the flowing from TERMINAL 9 of the masterSW to TERMINAL 4 is cut off, stopping the motor so that auto stop occurs.
3. Stopping of Auto Down AT Driver’s WindowWhen the manual SW (Driver’s) is pushed to the up side during auto down operation, a ground circuit opens in the masterSW and current does not flow from TERMINAL 3 of the master SW to TERMINAL 1, so the motor stops, causing auto downoperation to stop. If the manual SW is pushed continuously, the motor rotates in the up direction in manual up operation.
4. Manual Operation By Power Window Control SW (Passenger’s Window)With the power window control SW RH is pushed to the up side, the current flowing from TERMINAL 4 of the power windowcontrol SW RH flows to TERMINAL 3 of the power window control SW RH to TERMINAL 1 of the power window motor RH toTERMINAL 2 to TERMINAL 1 of the power window control SW RH to TERMINAL 2 to TERMINAL 10 of the master SW toTERMINAL 1 to GROUND. This causes the power window motor RH to rotate in the up direction. Up operation is continuousonly while the power window control SW RH is pushed to the up side. When the window descends, the current flowing to themotor flows in the opposite direction, from TERMINAL 1 to TERMINAL 2, and the motor rotates in revers.When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open. As aresult, even if Open/Close operation of the passenger’s window is tried, the current from TERMINAL 9 of the power windowmaster SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated and window lockoccurs.
5. Key Off Power Window OperationWith the ignition SW turned from on to off, the integration relay operates for about 43 seconds and current flows fromTERMINAL 1 of the power relay to TERMINAL 2 to GROUND. For this period, current also flows TERMINAL 5 to TERMINAL3. This current flows to TERMINAL 9 of the power window master SW and to TERMINAL 4 of the power window control SWRH. As a result, for about 43 seconds after the ignition SW is turned off, it is possible to raise and lower the power window bythe functioning of the integration relay. Also, by opening the door (Door courtesy SW on) within about 43 seconds afterturning the ignition SW to off, a signal is input to TERMINAL 3, 14 or 15 of the integration relay. As a result, the integrationrelay turns off, and up and down movement of the window stops.

Key Reminder and Seat Belt Warning (Access/Standard Cab)
Current always flows to TERMINAL (B) 23 of the combination meter through the DOME fuse.
1. Seat Belt Warning SystemWhen the ignition SW is turned on, current flows from the IGN fuse to TERMINAL (B) 24 of the combination meter. Thiscurrent activates the combination meter and the current flowing through the seat belt warning light flows from TERMINAL (B)12 to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL (A) 5 of the combinationmeter to TERMINAL (B) 12 to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL(A) 5 of the combination meter, the current flowing to TERMINAL (B) 23 of the combination meter flows from TERMINAL (B)12 to GROUND and the seat belt warning buzzer sounds. However, if the seat belt is put on during this period (While thebuzzer is sounding), signal input to TERMINAL (A) 5 of the combination meter stops and the current flow from TERMINAL(B) 23 of the combination meter to TERMINAL (B) 12 to GROUND is cut, causing the buzzer to stop.

Air Conditioning (Access/Standard Cab)
1. Heater Blower Motor OperationCurrent is applied at all times through the HTR fuse to TERMINAL 5 of the HTR relay.When the ignition SW is turned on, current flows through the GAUGE fuse to TERMINAL 2 of the HTR relay to the coil sideto TERMINAL 1 to TERMINAL 3 of the blower SW.
∗ Low speed operationWhen the blower SW is moved to LO position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, causing the HTR relay to switch on. This causes the current to flow from the HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 4 of the blower resistor toTERMINAL 1 to GROUND, causing the blower motor to rotate at low speed.
∗ Medium speed operation (Operation at M1, M2)When the blower SW is moved to M1 position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, turning the HTR relay to switch on. This causes the current to flow from the HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 4 of the blower resistor toTERMINAL 3 to TERMINAL 4 of the blower SW to TERMINAL 1 to GROUND. At this time, the blower resistance of theblower resistor is less than at low speed, so the blower motor rotates at medium low speed.When the blower SW is moved to M2 position, current flows through the motor flows from TERMINAL 4 of the blowerresistor to TERMINAL 2 to TERMINAL 8 of the blower SW to TERMINAL 1 to GROUND. At this time, resistance of theblower resistor is less than at M1 position, so the blower motor rotates at medium high speed.
∗ High speed operationWhen the blower SW is moved to HIGH position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, turning the HTR relay to switch on.This causes the current to flow from the HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 1 of theblower motor to TERMINAL 2 to TERMINAL 5 of the blower SW to TERMINAL 1 to GROUND, causing the blower motor torotate at high speed.
2. Operation of Air Inlet Control Servo Motor∗ Switching from FRESH to RECIRC
With the ignition SW turned on, current flows from the GAUGE fuse to TERMINAL 5 of the air inlet control servo motor.When the RECIRC/FRESH SW is switched to the RECIRC side, current flows from TERMINAL 5 of the air inlet controlservo motor to TERMINAL 1 to TERMINAL (A) 8 of the integration control and panel to TERMINAL (B) 1 to GROUND. Themotor rotates and the damper moves to the RECIRC side. When it is in the RECIRC position, current is cut inside theservo motor and the damper stops at that position.
∗ Switching from RECIRC to FRESHWith the ignition SW turned on, when the RECIRC/FRESH SW is switched to the FRESH side, current flows fromTERMINAL 5 of the air inlet control servo motor to TERMINAL 2 to TERMINAL (A) 7 of the integration control and panel toTERMINAL (B) 1 to GROUND, the motor rotates and the damper moves to the FRESH side. when it is in the FRESHposition, current is cut inside the servo motor and the damper stops at that position. When the ignition SW turned on, andmode SW (Integration control and panel) is at DEF or F/DEF position, it causes the damper to move to the FRESH side.Whether the RECIRC/FRESH SW (Integration control and panel) is on or not.
3. Air Conditioning OperationWhen the blower SW is on, current flows from the GAUGE fuse to the HTR relay (Coil side) to TERMINAL 3 of the blowerSW to TERMINAL 1 to GROUND, activating the HTR relay. This causes current to flow from the HTR fuse to the HTR relay(Point side) to A/C fuse to TERMINAL (B) 12 of the A/C SW (Integration control and panel). When the A/C SW (IntegrationControl and panel) is turned on. Current flows from the A/C fuse to TERMINAL (B) 14 of the integration control and panel toTERMINAL (B) 18 to A/C magnetic clutch. Causing The compressor to operate.When blower SW is on and mode SW (Integration control and panel) is at DEF or F/DEF position, it causes A/C to runwhether A/C SW (Integration control and panel) is on or not.

Engine Control (Double Cab)
The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof the engine control is given here.
1. Input Signals(1) Engine coolant temp. signal circuit
The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.
(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B, OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal isinput into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA1, VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor, detects the vehicle speed and input to the speed sensor of the skid control ECU withactuator, from skid control ECU to TERMINAL SPD of the engine control module, via combination meter.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B, +B2 of theengine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, andvoltage is constantly applied to TERMINAL +BM.
(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine controlmodule as a control signal.

2. Control System∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50, #60, #70, #80 to operate theinjector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the drivingconditions.
∗ ESA systemThe ESA system monitors the engine condition through the signals input from each sensors to the engine control module.The best ignition timing is decided according to this data and the data memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control theigniter to provide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINALS HT1B and HT2B to control theheater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low) and warms up the air fuel ratio sensor to improve detection performance of the sensor. The engine control module evaluates the signals from each sensor, current is output to TERMINALS A1A+ and A2A+controlling the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump withthe F/PMP relay.
∗ ETCS-iThe ETCS-i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail-Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail-safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

With the ignition SW turned on, current flows to TERMINAL 17 of the wiper and washer SW and TERMINAL 2 of the wipermotor through the WIP fuse. The current flows to TERMINAL 3 of the washer motor through the WSH fuse.
1. Low Speed PositionWith wiper SW turned to LOW position, current flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 7 toTERMINAL 5 of the wiper motor to TERMINAL 4 to GROUND and causes the wiper motor to run at low speed.
2. High Speed PositionWith wiper SW turned to HIGH position, current flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 8 toTERMINAL 3 of the wiper motor to TERMINAL 4 to GROUND and causes the motor to run at high speed.
3. INT PositionWith wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows fromTERMINAL 17 of the wiper and washer SW to TERMINAL 2 to GROUND. This flowing the intermittent circuit and currentflows from TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the wiper motor to TERMINAL 4 toGROUND and the wiper functions.The intermittent operation is controlled by charging and discharging of the condenser installed in the relay and theintermittent time is controlled by a time control SW to change the charging time of the condenser.
4. Washer Interlocking OperationWith the washer SW pulled up, current flows from TERMINAL 3 of the washer motor to TERMINAL 4 to TERMINAL 11 of thewiper and washer SW to TERMINAL 2 to GROUND and causes to the washer motor to run, and the window washer is jetted.This causes current to flow to washer continuous operation circuit in TERMINAL 17 of the wiper and washer SW toTERMINAL 7 to TERMINAL 5 of the wiper motor to TERMINAL 4 to GROUND and the wiper functions.

The electronically controlled transmission electrically controls the, throttle pressure, lock-up pressure, and accumulatorpressure etc. through the solenoid valve.The electronically controlled transmission is a system which precisely controls the gear shift timing and lock-up timing inresponse to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth drivingpossible by shift selection of the gear which is the most appropriate to the driving conditions at that time, and by preventingdowning, squat and gear shift shock when starting off.
1. Gear Shift OperationWhen driving, the engine warm up condition is input as a control signal from the engine coolant temp. sensor to TERMINALTHW of the engine control module, and the vehicle speed is input to TERMINAL SP2+ of the engine control module from thevehicle speed sensor. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA1, VTA2 of the engine control module as a throttle angle signal. Based on these signals, the engine controlmodule selects the best shift position for the driving conditions and sends current to the electronically controlled transmissionsolenoid.
2. Lock-Up OperationWhen the engine control module decides based on each signal that the lock-up condition has been met, the current flowsthrough TERMINAL SLU+ of the engine control module to TERMINAL 5 of the electronically controlled transmission solenoidto TERMINAL 13 to TERMINAL SLU- of the engine control module to GROUND.
3. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock-up position, a signal is input to TERMINAL STP ofthe engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock-up.
4. Overdrive Circuit∗ O/D main SW on
When the O/D main SW is switched to ON position, a signal is input to TERMINAL ODMS of the engine control module,and enables shift change to the overdrive range, through the control of the engine control module.
∗ O/D main SW offWhen the O/D main SW is switched to OFF position, a signal is input to TERMINAL ODMS of the engine control module,and prohibits shift change to the overdrive range through the control of the engine control module. When in the overdriverange already, shift down is made.

Cruise Control (Double Cab)
The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valveby the SW, and allows driving at a constant speed without depressing the accelerator pedal.
1. Set ControlWhen the - SET SW is operated while traveling with the ON-OFF SW on, the speed when the - SET SW is operated to offis memorized, and the vehicle speed is controlled at that speed.
2. Coast ControlWhen the - SET SW is operated to on, the cruise control opening angle requirement is turned to 0 to decrease the vehiclespeed, and the speed when the - SET SW is operated to off is memorized, and the vehicle speed is controlled at that speed.Furthermore, every time the - SET SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isdecreased by approx. 1.6 km/h (1.0 mph).
3. Accel ControlWhen the + RES SW is operated to on, the throttle motor rotates the throttle valve to open direction to increase the vehiclespeed, and the speed when the + RES SW is operated to off is memorized, and the vehicle speed is controlled at thatspeed.Furthermore, every time the + RES SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed isincreased by approx. 1.6 km/h (1.0 mph).
4. Manual Cancel MechanismIf any of the following signals are input during cruise control traveling, the current to the motor flows in the direction to closethe throttle valve, and cancel the cruise control.(1) Stop lamp SW is on (Brake pedal is depressed)
(2) The CANCEL SW of the control SW is on
(3) ON-OFF SW is off
(4) Gear is shifted from D position to other positions than D.
5. Resume ControlAfter canceling the cruise control (Except when the ON-OFF SW is off) if the vehicle speed is above the minimum speedlimit (Approx. 40km/h, 25mph), operating the + RES SW to on from off will cause the system to accelerate and resume to thevehicle speed before manual cancellation.
6. Overdrive FunctionThe overdrive may be cut on an uphill grade, while traveling with the cruise control.After the overdrive is cut, when the throttle opening information indicates the hill climbing is finished after the overdrive iscanceled, the vehicle returns to overdrive mode again as the overdrive return timer is completed, and if the systemdetermines that the uphill grade has finished, the overdrive will resume after the overdrive timer operation.
7. Auto Cancel OperationIf any of the following conditions are detected, the control is canceled.(1) Disconnection and/or short in the stop light SW
(2) Malfunction in the vehicle speed signal
(3) Malfunction in the electronic throttle parts
(4) Malfunction in the stop light SW input circuit
(5) Malfunction in the cancel circuit
(6) When the vehicle speed gets slower than the low speed limit.
(7) The actual vehicle speed becomes -16 km/h (10 mph) slower than the set speed

VSC (Double Cab)
1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the fourwheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedalis depressed suddenly, the skid control ECU controls the solenoids in the actuators using the signals from the sensors tomove the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the skid controlECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators toincrease the braking pressure.
2. Traction Control OperationThe traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of thewheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stabilitycorresponding to the road conditions.
3. VSC OperationUnexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- orover-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes toreduce the under- or over-steering.To reduce large over-steering :If the VSC system determines that the over-steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the over-steering.To reduce large under-steering :If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheelbrakes to reduce the under-steering.Traction control SWThe traction control SW is used to stop the TRAC function. After the engine is started, the TRAC system is stopped (turnedoff) and the VSC OFF indicator light lights up. When the traction control SW is pressed again, the TRAC system enters thestand-by mode. If the engine is stopped and restarted, the TRAC system enters the stand-by mode regardless of thetraction control SW.
4. Mutual System ControlTo efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlledwhile the VSC system is being operated.Engine throttle controlThe engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing theengine output.Engine control and electronically controlled transmission controlThe strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. andreducing changes in the driving torque at shift-down.VSC system operation indicationThe Slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whilethe VSC system is being operated.
5. Fail Safe FunctionIf an error occurs in the skid control ECU with actuator, sensor signals, and/or actuators, the skid control ECU with actuatorinhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal, thebrake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open requestfrom the VSC system. As a result, the vehicle functions regardless of the ABS, TRAC, and VSC systems.

ABS (Double Cab)
This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left frontwheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.This results in improved directional stability and steerability during panic braking.
1. Input Signal(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS actuator with ECU.(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS actuator with ECU when the brake pedal is depressed.
2. System OperationDuring sudden braking, the ABS actuator with ECU which has signals input from each sensor lets the hydraulic pressureacting on each wheel cylinder escape to the reservoir.The pump inside the ABS actuator with ECU is also operating at this time and it returns the brake fluid from the reservoir tothe master cylinder, thus preventing locking of vehicle wheels.If the ABS actuator with ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current actingon the solenoid is controlled and the hydraulic pressure is increased.Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressurereduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

Then a signal is input into TERMINAL (A) 15 ofthe 4WD control ECU and the 4WD control ECU is activated by this, so the current flows from the 4WD control ECUTERMINAL (B) 2 to transfer shift actuator TERMINAL 2 to motor to TERMINAL 1 to 4WD control ECU TERMINAL (B) 1 toGROUND. The transfer shifts to 4WD LO position (L4 position), and the 4LO indicator light comes ON.

SRS (Double Cab)
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and thenegative (-) terminal cable is disconnected from the battery.(The SRS is equipped with a back-up power source so that if work is started within 90 seconds fromdisconnecting the negative (-) terminal cable of the battery, the SRS may deploy.)
When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back-up power supply from outside the vehicle.
Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
Do not expose the following parts directly to hot air or flame;
Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
For the purpose of reuse, never disassemble and repair the following parts.
If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.
Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
After work on the SRS is completed, check the SRS warning light.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

The SRS is a driver protection device which has a supplemental role to the seat belts.When the ignition SW on, the current from the IGN1 fuse flows to TERMINAL (A) 21 of the center airbag sensor assembly.If an accident occurs while driving, deceleration caused by a frontal impact is detected (by sensor) and when the frontalimpact exceeds a set level, the current from the IGN1 fuse flows to TERMINAL (A) 21 of the center airbag sensor assembly.This current flows to TERMINALS (A) 4, (A) 5, (B) 4, (B) 5, (C) 4, (C) 5 to TERMINAL 1 of the airbag squib and Pretensionersto TERMINAL 2 to TERMINALS (A) 3, (A) 6, (B) 3, (B) 6, (C) 3, (C) 6 of the center airbag sensor assembly. Furthermore, thecurrent flows to TERMINAL (A) 25 or (A) 26 to GROUND, causing the center airbag squibs to expand.When the safing sensor built into the center airbag sensor assembly is on, airbag sensor is off and the current from the IGN1fuse flows same as above-mentioned flowing, causing the airbag squibs to expand. When the safing sensor built into thecenter airbag sensor assembly is on, the airbag sensor on one of the above-mentioned circuits is activated so that currentflows to the airbag squibs and causes them to operate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to thepassenger.

Air Conditioning (Double Cab)
1. Heater Blower Motor OperationCurrent is applied at all times through the HEATER fuse to TERMINAL 5 of the HTR relay.When the ignition SW is turned on, current flows through the HTR fuse to TERMINAL 2 of the HTR relay to the coil side toTERMINAL 1 to TERMINAL 3 of the blower SW.
∗ Low speed operationWhen the blower SW is moved to LO position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, causing the HTR relay to switch on. This causes the current to flow from the HEATER fuse to TERMINAL 5 ofthe HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistorto TERMINAL 1 to GROUND, causing the blower motor to rotate at low speed.
∗ Medium speed operation (Operation at M1, M2)When the blower SW is moved to M1 position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, turning the HTR relay to switch on. This causes the current to flow from the HEATER fuse to TERMINAL 5 ofthe HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistorto TERMINAL 3 to TERMINAL 4 of the blower SW to TERMINAL 1 to GROUND. At this time, the blower resistance of theblower resistor is less than at low speed, so the blower motor rotates at medium low speed.When the blower SW is moved to M2 position, current flows through the motor flows from TERMINAL 4 of the blowerresistor to TERMINAL 2 to TERMINAL 8 of the blower SW to TERMINAL 1 to GROUND. At this time, resistance of theblower resistor is less than at M1 position, so the blower motor rotates at medium high speed.
∗ High speed operationWhen the blower SW is moved to HIGH position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 toGROUND, turning the HTR relay to switch on.This causes the current to flow from the HEATER fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2of the blower motor to TERMINAL 1 to TERMINAL 5 of the blower SW to TERMINAL 1 to GROUND, causing the blowermotor to rotate at high speed.
2. Operation of Air Inlet Control Servo Motor∗ Switching from FRESH to RECIRC
With the ignition SW turned on, current flows from the HTR fuse to TERMINAL 5 of the air inlet control servo motor. Whenthe RECIRC/FRESH SW is switched to the RECIRC side, current flows from TERMINAL 5 of the air inlet control servomotor to TERMINAL 1 to TERMINAL (A) 8 of the integration control and panel to TERMINAL (B) 10 to GROUND. Themotor rotates and the damper moves to the RECIRC side. When it is in the RECIRC position, current is cut inside theservo motor and the damper stops at that position.
∗ Switching from RECIRC to FRESHWith the ignition SW turned on, when the RECIRC/FRESH SW is switched to the FRESH side, current flows fromTERMINAL 5 of the air inlet control servo motor to TERMINAL 2 to TERMINAL (A) 7 of the integration control and panel toTERMINAL (B) 10 to GROUND, the motor rotates and the damper moves to the FRESH side. when it is in the FRESHposition, current is cut inside the servo motor and the damper stops at that position. When the ignition SW turned on, andmode SW (Integration control and panel) is at DEF or F/DEF position, it causes the damper to move to the FRESH side.Whether the RECIRC/FRESH SW (Integration control and panel) is on or not.
3. Air Conditioning OperationWhen the blower SW is on, current flows from the HTR fuse to the HTR relay (Coil side) to TERMINAL 3 of the blower SW toTERMINAL 1 to GROUND, activating the HTR relay. This causes current to flow from the HEATER fuse to the HTR relay(Point side) to A/C fuse to TERMINAL (B) 14 of the A/C SW (Integration control and panel). When the A/C SW (IntegrationControl and panel) is turned on. Current flows from the A/C fuse to TERMINAL (B) 14 of the integration control and panel toTERMINAL (B) 18 to A/C magnetic clutch. Causing The compressor to operate.When blower SW is on and mode SW (Integration control and panel) is at DEF or F/DEF position, it causes A/C to runwhether A/C SW (Integration control and panel) is on or not.

VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the checkpoint.Example:
[A] - Ignition SW on[B] - Ignition SW and SW 1 on[C] - Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.
(b) Contact the two leads of an ohmmeter to each of the checkpoints.
If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the fuse.(b) Connect a test light in place of the fuse.(c) Establish conditions in which the test light comes on.
Example:[A] - Ignition SW on[B] - Ignition SW and SW 1 on[C] - Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.
(e) Find the exact location of the short by lightly shaking theproblem wire along the body.
CAUTION:(a) Do not open the cover or the case of the ECU unless
absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).
DISCONNECTION OF MALE AND FEMALECONNECTORS
