THEORY OF OPERATION

The Transmission Control Module controls the gear ratio by the use of a Step motor that transfers electrical power to mechanical movement. The rationality is a continuous test that monitors the Step motor movement.

When the difference between the estimated and actual primary pulley speed has reached 1000 RPM, a DTC will set.

P0746-LINE PRESSURE SOLENOID PERFORMANCE

Fig. 49: Pressure Control Solenoid Control Wiring Diagram



& Patriot


128



THEORY OF OPERATION

The Line Pressure Solenoid regulates the Line Pressure (Oil Pump discharge pressure) which is controlled by the Transmission Control Module (TCM). If the line pressure does not reach at the desired pressure due to driving conditions, the possibility of belt slippage can occur. The gear ratio changes to a value beyond the maximum gear ratio which is a calculation between the Primary Pulley speed and the Secondary Pulley speed. If the gear ratio exceeds a predetermined limit a DTC will set.

WHEN MONITORED





Primary Pulley Speed grater than 500 RPM.

P1744-TORQUE CONVERTER LOCK-UP CLUTCH HEAT CONTROL

THEORY OF OPERATION

The Transmission Control Module (TCM) monitors the Torque Convertor Clutch for temperature during normal operation. To protect the CV Transmission from a hot temperature condition, the TCM monitors the continuation time of stall speed condition.

& Patriot


276



THEORY OF OPERATION



& Patriot


277

The Transmission Control Module monitors two signals from the TCC Solenoid during normal operation. One is the feedback electric current of the TCC Solenoid and the other is the voltage between ground and the TCM termination for the TCC Solenoid.

WHEN MONITORED

SET CONDITION

If the target current is greater than 0.75 of an amp and the monitored current is less than 0.4 of an amp for the period of five seconds. It takes two consecutive problem identification trips for the DTC to mature and illuminate the MIL.

STANDARD PROCEDURE

CVT - PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

For a complete wiring diagram refer to appropriate SYSTEM WIRING DIAGRAMS article .

Perform the following pre-diagnostic troubleshooting procedures prior to performing any diagnostic test.

Always perform diagnostics with a fully charged battery to avoid false symptoms. The Transmission Control Module (TCM) requires a system voltage between 9 and 16 volts.

1. Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any leaks and fill the transmission to the proper fluid level. Refer to STANDARD PROCEDURE for the proper repair and fluid fill procedures.

2. With the scan tool, read Engine DTCs. If Engine DTCs are present, refer to DTC INDEX and perform to the appropriate diagnostic procedure(s) before proceeding. .

3. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information. Diagnose any Pending DTC as a matured DTC.

4. Use the wiring diagram as a guide, inspect the wiring and connectors related to this circuit and repair as necessary.

5. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving under specific conditions, and after controller diagnostic monitors have run or otherwise know as a Good Trip.

CAUTION: The CVT Transmission uses a specific green transmission fluid that is substantially different from standard ATF used in other automatic transmissions. Failure to use the proper fluid will result in excessive transmission damage or total failure. Refer to CAPACITIES AND RECOMMENDED FLUIDS for the proper fluid type.



& Patriot


335

6. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply. Check for controller software update information. Some conditions can be corrected by upgrading the Engine (PCM) or Transmission (TCM) controller software.

Did any of the above procedures repair the vehicle?

Yes

� Testing is complete.


No

� Refer to DTC INDEX and perform the appropriate symptom(s). .

CVT VERIFICATION TEST

Perform the following after completion of a diagnostic repair:

1. Reconnect any disconnected components.

2. With the scan tool, erase all Transmission and Engine DTCs.

3. If the Transmission Control Module or the Transmission has been repaired or replaced, it is necessary to perform the scan tool Initialize CVT Re-learn Procedure. Refer to MODULE, TRANSMISSION CONTROL, STANDARD PROCEDURE .

4. With the scan tool, display Transmission Temperature. Start and run the engine until the transmission temperature is HOT, above 43° C or 110° F.

5. Check the transmission fluid and adjust if necessary. Refer to STANDARD PROCEDURE for the Fluid Fill procedure.

6. Road test the vehicle. With the scan tool, monitor the engine RPM and

CAUTION: The CVT uses a specific transmission fluid type that is green in color. Do not use a standard ATF fluid. Doing so can damage the transmission. Make sure to follow the Service Information fluid type and fill procedure.



& Patriot


336

throttle angle. Drive the vehicle from a standing start to 45 mph with a constant throttle opening of 20 to 25 degrees with an engine speed above 450 RPM.

7. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set condition to verify the DTC is repaired.

8. If equipped with AutoStick®, upshift and downshift several times using the AutoStick® feature during the road test.

9. Check for any Diagnostic Trouble Codes (DTCs) during and after the road test.

Did any Diagnostic Trouble Codes set during the road test?

Yes

� Repair is not complete. Refer to DTC INDEX and perform the appropriate symptom(s). .

No


NOTE: Use the OBDII task manager to run a Good Trip. This will confirm the repair(s) made and to ensure the DTC has not re-matured.
