3. RECAP

Procedure

To run fault finding on the vehicle computers, switch on the ignition.

Fault

Faults are declared as either present or stored (depending on whether they appeared in a certain context and have disappeared since, or whether they remain present but have not been diagnosed within the current context).

The present or stored status of the fault should be taken into consideration when the diagnostic tool is used after the + after ignition feed has been connected (without any of the system components being activated).

For a present fault, apply the procedure described in the Interpretation of faults section.

For a stored fault, note the faults displayed and apply the Notes section.

If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault

If the fault is not confirmed, check:– the electrical lines which correspond to the fault,– the connectors for these lines (for oxidation, bent pins, etc.),– the resistance of the component detected as faulty,– the condition of the wires (melted or cut insulation, wear).

Or use the fault finding procedure to check the circuit of the component concerned.

Check conformity

The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the data is inconsistent. Therefore, this phase allows:– run fault finding on faults that do not have a fault display, and which may correspond to a customer complaint,– a check to be carried out to check that the system is operating correctly and that there is no risk of a fault recurring

after repairs.

This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.

If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the corresponding fault finding page.

Customer complaints - Fault finding chart

If the diagnostic tool check is in order, but the customer complaint is still present, the fault should be dealt with by customer complaints.

A summary of the overall procedure to follow is provided on the following page in the form of a flow chart.

4. FAULT FINDING PROCEDURE (continued)

Wiring check

Fault finding problemsDisconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.Electrical voltage, resistance and insulation measurements are generally correct, especially if the fault is not present when the analysis is made (stored fault).

Visual inspectionLook for damage under the bonnet and in the passenger compartment.Carefully check the protective parts, insulators and wiring harness routing.Look for signs of oxidation.

Tactile inspectionWhile manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to present.Make sure that the connectors are properly locked.Apply light pressure to the connectors.Twist the wiring harness.If there is a change in status, try to locate the source of the fault.

Inspection of each componentDisconnect the connectors and check the appearance of the clips and tabs, as well as their crimping (no crimping on the insulating section).Make sure that the clips and tabs are properly locked in the sockets.Check that no clips or tabs have been dislodged during connection.Check the clip contact pressure using an appropriate model of tab.

Resistance checkCheck the continuity of entire lines, then section by section. Look for a short circuit to earth, the + 12 V feed or with another wire.

If a fault is detected, repair or replace the wiring harness.

5. FAULT FINDING LOG

You are always asked for this log:– when requesting technical assistance from the Techline,– for approval requests when replacing parts for which approval is obligatory,– to be enclosed when returning monitored parts on request. The log is needed for warranty compensation, and

enables better analysis of the parts removed.

6. SAFETY ADVICE

Safety rules must be observed during any work on a component to prevent any damage or injury:– make sure the battery is properly charged to avoid damaging the computers with a low load,– use the appropriate tools.

WARNING

IMPORTANTAny fault on a complex system requires a full fault finding procedure with the appropriate tools. The FAULT FINDING LOG, which should be completed during the procedure, enables you to keep track of the procedure which is carried out. It is an essential document when consulting the manufacturer.

IT IS MANDATORY TO FILL OUT A FAULT FINDING LOG FOR EACH FAULT FINDING PROCEDURE.

SEMIAUTOMATIC GEARBOXFault finding - System operation 21B

21B - 7V3MR-379-X70-21B000$130_eng.mif


SEMIAUTOMATIC GEARBOXFault finding - System operation

Having already converted the "JH" gearbox to semiautomatic for the Twingo and Clio, Renault has now converted the "PK6" for the Trafic and Master. The converted PK6 is known as the PA6

The electrohydraulic system attached to the gearbox comprises two actuators, one for gear selection and changing, the other for operating the clutch, and a hydraulic power unit which supplies power to the actuators.

The assembly is linked to the semiautomatic gearbox computer, which itself is linked to the engine computer by a CAN connection. The gear lever is used to select gears: in automatic mode, gear changes are controlled by the computer which uses auto-adaptive shift patterns; in manual mode, the driver moves a lever, which via the computer, changes the gears.

When the gear is changed, the semiautomatic gearbox computer controls the engine management computer and the torque in such a way as to reduce jolts, leaving the driver free to leave his foot on the accelerator.

Description of user operation:

The interface between the driver and the semiautomatic gearbox system inside the passenger compartment comprises:

– a gear lever (mechanical section and internal electronic section),– a display,– a TRACTION CONTROL (snow mode) button,– a LOAD mode button,– a buzzer.

Using this interface, the driver can:– request gear changes (up or down),– request a specific gear change (into neutral or reverse),– change between manual and automatic mode,– activate and deactivate the traction control mode,– activate and deactivate the load mode.

Description of passenger compartment control:

Description of gear lever positions:– S: Standby this is the only stable gear lever position. After each time the driver shifts the gear lever up or

down, it returns to the S position.– R: Reverse: moving the lever to this position enables the driver to select reverse. Given the lever position

of the reverse function, it is possible, if the movement is too slow, for the semiautomatic gearbox computer to read N and hence select neutral before reverse.

The automatic mode used by the semiautomatic gearbox is based on the design of the DP0 automatic gearbox which uses shift patterns which adapt automatically to the driving style and road conditions.The gear change is determined by a set of gear change graphs as a function of the accelerator pedal position and the vehicle speed.The semiautomatic gearbox is a manual gearbox with a hydraulic control.

21B - 8V3MR-379-X70-21B000$130_eng.mif


Description of gear lever positions (continued):– N: Neutral: moving the lever to this position enables the driver to select neutral.– A/M: AUTO/MANUAL: moving the lever to this position enables the driver to select either manual mode (or

semiautomatic) or automatic mode. If AUTO mode is selected, moving the lever will enable the driver to select manual mode, if manual mode is selected; moving the lever will enable the driver to select automatic mode.

– +: moving the gear lever towards this position enables the driver to shift up. If AUTO mode is selected, this action will also enable the driver to exit automatic mode.

– -: moving the gear lever towards this position will enable the driver to shift down. If AUTO mode is selected, this action will also enable the driver to exit automatic mode.

Description of the TRACTION CONTROL button:

This is a one touch button. Pressing this button once allows the driver to select or deselect the TRACTION CONTROL mode.

Description of the LOAD button:

This is a one touch button. Pressing this button once allows the driver to select or deselect the LOAD mode.

Description of the display:

This display is designed for the PA6 gearbox. It features 6 displays to aid the driver:– indicates the selected gear: 1, 2, 3, 4, 5, 6, N or R,– the symbol displaying AUTO (A) mode: this symbol lights up when auto mode is selected.– the TRACTION CONTROL indicator light: this lights up when the TRACTION CONTROL mode is selected.– the LOAD mode indicator light: this lights up when the LOAD mode is selected.– the depress brake pedal symbol: this symbol lights up when a driver action requires the brake pedal to be

depressed when the driver is not depressing the brake. This symbol only lights up when there is an error (driver actions without depressing the brake pedal = symbol lighting up).

– the semiautomatic gearbox fault warning light: this lights up when the semiautomatic gearbox computer detects a fault on the semiautomatic gearbox system.

General information about the function:

Operation in MANUAL mode:

Manual mode allows the driver to select gears by moving the gear lever. However, in manual mode, the driver is not completely free to do what he/she likes. This is why this mode is also called semiautomatic mode because the driver is assisted by the semiautomatic gearbox computer in the following instances:

– when driving, shifting the lever towards the + position may result in underspeed. As a result, the semiautomatic gearbox computer forbids the driver's request,

– when driving, shifting the lever towards the - position may result in overspeed. As a result, the semiautomatic gearbox computer forbids the driver's request,

– when driving, as the overspeed threshold is approached, the computer automatically selects a higher gear,– when driving, as the underspeed threshold is approached, the computer automatically selects a lower gear,– when driving, if the vehicle speed decreases too quickly (brakes applied), the semiautomatic gearbox

computer can order a downshift.– when driving, the selection of N is only accepted by the semiautomatic gearbox computer if the driver's foot

is on the brake pedal,– when driving, selection of reverse is prohibited,– when the vehicle is slowing and approaching 0 mph, the semiautomatic gearbox computer engages 1st gear

automatically.

In manual mode, the driver decides when to change gears by:– moving the gear lever towards +, which enables a higher gear to be selected,– moving the gear lever towards -, which enables a lower gear to be selected,– moving the gear lever to N, which enables neutral to be selected,– moving the gear lever to R, which enables reverse to be selected.

Operation in AUTOMATIC mode:

Automatic mode frees the driver from having to worry about changing gear: instead, the semiautomatic gearbox computer determines when best to change gear in relation to the different vehicle parameters (speed, acceleration, position of accelerator pedal etc.).

The main characteristics of automatic mode are as follows:– AUTO mode is only operational and accessible when the engine is running.– AUTO mode is preselected when the engine is started.

Reminder: creeping is only possible in first or reverse gears; it makes parking manoeuvres easier: if the brake pedal or the handbrake is released, the vehicle moves forward by itself, without the driver having to accelerate. Creeping is not possible in second gear.

BVR X7083 04 3.0


21B - 10V3MR-379-X70-21B000$130_eng.mif


Operation in AUTOMATIC mode (continued):

The AUTO mode entry conditions are as follows:– Moving the gear lever to the left (towards A/M) when manual mode is selected, when a forward gear is

engaged and AUTO mode was selected.– TRACTION CONTROL mode deselected by pressing the TRACTION CONTROL button.– Engine started up.

To exit the AUTO mode when driving and in rated operation (no faults), the following conditions must apply:– Movement of the gear lever to the left (deselecting automatic mode using the lever).– Movement of gear lever towards "+" (except when engaging R towards 1 or N towards "X").– Movement of the gear lever towards "-" (except when changing from N to X or when reverse gear is

engaged).– Engine switched off.– Ignition switched off or + Accessories active.– TRACTION CONTROL mode selected by pressing the TRACTION CONTROL button.

Operation of the TRACTION CONTROL mode:

The TRACTION CONTROL button imposes a special TRACTION CONTROL strategy which affects the middle levels (starting programming, gear change management) and the high levels (LAA). The TRACTION CONTROL mode does not impose starting in 2nd gear; starting is in 1st gear with special clutch management.

The main characteristics of the TRACTION CONTROL mode are as follows:– The TRACTION CONTROL mode imposes AUTO mode: if the driver presses the TRACTION CONTROL

when manual mode is selected, the semiautomatic gearbox switches to AUTO mode and TRACTION CONTROL mode.

– There is no TRACTION CONTROL mode in manual mode; TRACTION CONTROL mode is only active in AUTO mode.

– When the TRACTION CONTROL button is pressed while TRACTION CONTROL mode is active, TRACTION CONTROL mode is deselected, but AUTO mode remains active.

– TRACTION CONTROL is only operational and accessible after the engine is started.– The mode is not stored in the memory when the ignition is switched off; the driver must reselect snow mode

each time the engine is started.

The conditions for exiting TRACTION CONTROL mode are as follows:– TRACTION CONTROL button pressed.– Engine switched off.– Ignition switched off and + Accessories reactivated.– Select manual mode (move lever towards A/M).– Movement of the gear lever towards "+" (except when engaging R towards 1 or N towards "X").– Movement of the gear lever towards "-" (except when engaging R towards 1 or N towards "X").

When driving, if the lever is moved towards "+" or "-", TRACTION CONTROL mode is deselected (return to MANUAL mode) and the request is accepted.

BVR X7083 04 3.0


21B - 11V3MR-379-X70-21B000$130_eng.mif


Operation of the LOAD MODE:– The LOAD MODE is activated when the driver presses the LOAD button.– LOAD MODE is only accessible after the engine is started.– The mode is not stored in the memory when the ignition is switched off; the driver must reselect LOAD

MODE each time the engine is started.– If LOAD MODE is selected, the load indicator light comes on. However, if the computer detects a load even

though the button has not been pressed, the load indicator light will not come on.– LOAD MODE is independent of the other driving modes: LOAD MODE is active in manual mode, AUTO

mode and TRACTION CONTROL mode.– LOAD MODE is independent of all other driver actions (+, -, N, R, A/M).

Conditions for exiting LOAD MODE are as follows:– Switch off engine.– Ignition switched off or + Accessories active.– Load button pressed.

Buzzer function:

The buzzer operates in the following cases:

– Safety risk: the buzzer sounds when one of the front doors is opened, if the following conditions are met:– the engine is running,– a gear is engaged,– the driver is not applying the brakes.

– The buzzer cuts out if one of the following conditions is confirmed:– the engine is stopped,– the driver applies the brakes,– the driver closes the door(s).

– Driver warning when push-starting vehicle:– The buzzer will sound to inform the driver that moving the lever to select a gear will enable the engine to

start. The buzzer will sound when the vehicle has reached the speed that will allow the engine to start.

– When the computer detects that the clutch is overheating.

21B - 12V3MR-379-X70-21B000$130_eng.mif


Lever operation:– When the vehicle is stationary, the engine switched off and the key at + after ignition feed position, gear

changes are possible.– Each time the lever is moved, it returns to the S position automatically.– When the vehicle is stationary, the engine switched off and the key at + after ignition feed, position, lever

movements will only be considered if the driver depresses the brake pedal. In this case, all gears are available. The number of gear changes possible is unlimited.

– When the vehicle is stationary and the engine is running, lever movements will only be considered if the driver depresses the brake pedal. In this case, only N, 1, 2, R gears are available.

– Position N only allows neutral to be engaged if the driver depresses the brake pedal.– Position R enables reverse to be engaged. Reverse will only be engaged if the vehicle has stopped or has

nearly stopped and if the driver depresses the brake pedal. Engaging reverse when driving is prevented by the semiautomatic gearbox computer.

Operation of the display:

AUTO repeater:– AUTO ("A") symbol lit: it lights up when AUTO mode is selected.– Instrument panel display: the display shows "A" and the gear engaged.– Symbol goes out: it goes out when AUTO mode is deselected.

TRACTION CONTROL MODE repeater:– TRACTION CONTROL MODE symbol lit ("*"): it is lit when the TRACTION CONTROL MODE is selected

and accepted by the computer (pressing the TRACTION CONTROL MODE requires the switch to AUTO mode, hence the display "A" + "*").

– Instrument panel display: the display shows "*" + "A" + the gear engaged. the display is controlled in the same way as in AUTO mode.

– TRACTION CONTROL MODE goes out: the symbol goes out when TRACTION CONTROL mode is deselected.

LOAD MODE repeater:– The LOAD MODE symbol lit: it is lit when LOAD MODE is selected and accepted by the computer.– Instrument panel display: the display shows "C" + the gear engaged + "A" if AUTO mode is active or

"A" + "*" if TRACTION CONTROL MODE is active.– LOAD MODE goes out: The symbol goes out when LOAD MODE is deselected.

BVR X7083 04 3.0


21B - 13V3MR-379-X70-21B000$130_eng.mif


Display programming when gears cannot be engaged:– When a request leads to overspeed or underspeed: the requested gear flashes then initial gear reappears.

Flashing ends after a delay.– When there is a mechanical fault (gearbox blockage etc.): application of the retry (1) program by the

computer. During retry: the requested gear flashes; then, the engaged gear is displayed on the instrument panel at the end of the retry period. This program cannot be applied to neutral because the N position cannot flash on the instrument panel.

(1) RETRY: If there is a mechanical problem engaging a gear (lower or higher), the computer will detect this and will attempt to re-enage twice more; if this does not work, the requested gear will flash on the instrument panel display and the gearbox will return to the gear used prior to this request.

Depress brake pedal repeater:

This indicator is used when, during normal operation, it is necessary to depress the brake pedal and the driver has not done so. The indicator asks the driver to depress the brake pedal in order for his request to be accepted. Consequently: the symbol only lights up if there is a fault (driver action without brake pedal depressed = symbol lights up) and only if depressing the brake pedal allows the driver's request to be accepted.

– Depress brake pedal symbol lit:– request to change gear when stopped without the brake pedal depressed,– request to start engine with gear engaged without brake pedal depressed,– request to select N when driving without brake pedal depressed,– request to select AUTO, with the vehicle stationary, the engine running and 2nd gear engaged,– request to select TRACTION CONTROL MODE, with the vehicle stationary, the engine running and 2nd gear

engaged.

– Foot on brake symbol goes out:– The symbol goes out if the driver depresses the brake pedal or after an adjustable delay.

Fault warning light:

This warning light comes on when a fault is detected by the semiautomatic gearbox computer.

Note:If, while the symbol is lit, the driver depresses the brake pedal, the symbol will go out and the display will return to its previous status (the lever request is not acted upon).In the event that the driver makes a request causing the gear requested to flash and the symbol to be displayed at the same time, they will be synchronised and last for the same period of time.

Step 4

With a warm engine, carry out step 1 for each gear change (1st, 2nd, 3rd, 4th, 5th and 6th).

1) If there is an inconsistency in the engagement position sensor during these checks, check the wear on the cylinder-potentiometer mechanical connection (excessive play, mechanical connection broken or jammed).If the checks are correct, replace the engagement position sensor (see MR377 Mechanical systems, 21 B, Sequential gearbox, engagement sensor: Removal - Refitting).

2) If the engagement position sensor values differ from the neutral value, go to step 5.

Step 5

Start the engine, engage 1st gear and wait 15 seconds. Engage neutral and display the value of parameter PR017 “Engagement position”, wait 15 seconds and check that the value does not change.

1) Switch off the engine and wait 15 seconds, if it is impossible to push the vehicle, either the engagement solenoid valve or the engagement position sensor is the cause (see MR377 Mechanical systems, 21 B, Sequential gearbox, engagement sensor: Removal - Refitting) and (see MR408 Mechanical systems, 21B, Solenoid valves: Removal - Refitting).

2) If it is possible to push the vehicle: go to step 6

Step 6

Start the engine, engage 2nd gear and wait 15 seconds. Engage neutral and display the value of parameter PR017 “Engagement position”, wait 15 seconds and check that the value does not change. Switch off the engine and wait 15 seconds, if it is impossible to push the vehicle, either the engagement solenoid valve or the engagement position sensor is the cause (see MR377 Mechanical systems, 21 B, Sequential gearbox, engagement sensor: Removal - Refitting) (see MR 408 Mechanical systems, 21B Solenoid valves: Removal - Refitting).

No communication with the semiautomatic gearbox computer

NOTESSpecial notes:Only consult this customer complaint after a complete check with the diagnostic tool.

Check that the diagnostic tool is not causing the fault by trying to establish dialogue with a computer on another vehicle. If the tool is not causing the fault and dialogue cannot be established with any other computer on the same vehicle, it may be that a faulty computer is disrupting fault finding line K.Proceed by successive disconnections to locate this computer.Check the battery voltage and carry out the necessary work to obtain the correct voltage (9.5 V < battery voltage < 17.5 V).

Check the presence and condition of the semiautomatic gearbox fuses on the passenger compartment fuse board (5 A) and in the engine fuse box (5 A, 10 A, 30 A).Check that the computer connector is properly connected and the condition of its connections.Check the semiautomatic gearbox earths (quality, rusting, tightness of the earth bolts on top of the hydraulic unit).Check that the supply to the computer is correct:

– Earth on tracks 1 and 2 of the 52-track connector.– + before ignition on track 27 of the 52-track connector.– + after ignition feed on track 28 of the 52-track connector.

Ensure that the supply to the diagnostic socket is correct:– + before ignition feed on track 16.– + after ignition feed on track 1– Earth on track 5.

Check and ensure the continuity and insulation of the connection between:Computer connector track 49 track 7 diagnostic socket.

If dialogue has still not been established after these various checks, contact the Techline.

AFTER REPAIRClear the computer's fault memory. Switch off the ignition and wait 20 seconds.Carry out a road test followed by another check with the diagnostic tool.

NOTES

Special notes:Only consult this customer complaint after a complete check with the diagnostic tool.In a case where there is no creep, if the customer has heard the buzzer whilst driving, it is normal for creep to be prohibited (clutch overheating). Let the clutch cool down and check that creeping is once again active. If the fault is still present, apply the procedure detailed below.

Check for the presence and condition of the brake light fuse in the passenger compartment fuse box.Check that the connectors for the brake light switch and handbrake switch are correctly connected and check the condition of the wiring as well as that of the computer. Repair if necessary.Check that the brake lights switch on the pedal is correctly fitted and adjusted.With the pedal depressed, check the continuity between tracks A3 and B1 on the switch. Replace the switch if necessary.With the pedal released, check that there is no continuitybetween tracks A3 and B1 of the switch. Replace the switch if necessary.If the fault is still present, check the continuity of the connection between:

Switch track A3 Track 69 28-track computer connectorCheck the condition of the handbrake switch on its support.

– The acoustic warning is active:– when the front doors are opened,– if the clutch overheats only while the vehicle is being driven.– if the semiautomatic gearbox programming has not been carried out.

– The foot on brake symbol is active:– When the engine is running on a gear lever request or if the lever is accidentally shifted to the neutral

position while the vehicle is being driven.Carry out a road test to recreate the customer complaint.Carry out the following programming:

– VP008 "Program selection / engagement ranges".– Clear the biting point programming using command:

RZ003 "Program biting point".Exit fault finding mode and switch off the ignition.Wait 1 minute and then re-establish dialogue with the computer.Shift the gear lever to neutral (Stb).Start the engine.Wait 10 seconds without changing gear (for programming the clutch biting point).Check that the programming has been correctly performed using the following status:ET062 "Program biting point" = "Done".Repeat the procedure if unsuccessful.
