STOREDCLUTCH PEDAL CIRCUIT
1.DEF: Component in bad condition
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present with the engine running and following a check on the number of
times the clutch pedal is depressed in relation to the number of gear changes
calculated by the computer.
Special note:
– engine speed surges when changing gear,
– the acquisition is made if the vehicle is not fitted with an automatic transmission,
– in the event of a fault, before replacing any component, check using the diagnostic
tool that the clutch contact is operational and that the recommended clutch pedal
clearance is still valid.
– In the event of an open circuit or short circuit to + 12 V, the clutch pedal is
depressed all the time which makes it impossible to select a cruising speed in cruise
control mode. The speed limiter remains operational in defect mode (inaccurate
speed restriction),
–If short circuit to earth, status ET405 Clutch pedal switch remains INACTIVE.
Check the cleanliness, condition and fitting of the clutch pedal switch.
Repair if necessary.
If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is
closed, and when the clutch pedal is released, the switch is open.
Replace the switch if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any damage to the wiring harness, and check the condition and connection of the connectors of the
injection computer and clutch pedal switch.
Repair if necessary.
If the fault is still present, check the earth on track 2 of the switch.
If the earth is not present on track 2, check for insulation, continuity and the absence of interference
resistance on the following connection:
earth track 1 Clutch pedal switch
Repair if necessary.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.

NOTESPriority when dealing with a number of faults:
If faults DF154, DF119 Camshaft sensor circuit and DF080 Camshaft dephaser
circuit are present, ignore DF080 and deal with the other 2 faults first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the starter motor has been running for 10 seconds
or at an engine speed above 600 rpm.
Special note:
–the OBD warning light is lit,
– In the event of flywheel signal loss, the injection and ignition are cut off: the vehicle
stalls and cannot be restarted.
1.DEF
NOTESNone.
Check the cleanliness, condition and the fitting of the flywheel.
Repair if necessary.
If the flywheel has been replaced or removed, the flywheel target has to be reinitialised, then reprogrammed.
Programming reinitialisation:
Use command RZ005: Programming.
Carrying out the flywheel target programming:
– Decelerate a first time with injection cut-off (i.e. feet off the brake, accelerator pedal and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for a manual gearbox and 2nd for automatic gearbox, for at least 5 seconds.
– Decelerate a second time with injection cut-off (i.e. brake, accelerator and clutch pedals released) between
2400and 2000 rpm for K4 engines and between 1800 and
1400 rpm for F4R engines, in 3rd gear for a manual gearbox and 2nd for an automatic gearbox, for at least
5 seconds.
After the operation, check that status ET089 Flywheel target programming is COMPLETED.
(*This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque).
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
