– check the sensor/flywheel air gap,
– check the cylinder compressions,
– check the complete fuel supply system (see Workshop Repair Manual 364 or 370 Mechanics, 13A, Fuel
supply),
– check the complete ignition system (see MR 364 or 370 Mechanics, 17A, Ignition),
– check the hydraulic tappets if there is camshaft noise (see MR 364 or 370 Mechanics, 11A, Top and front of
engine).

1.DEF: Component in bad condition
2.DEF: Non-compliance with emission control standards
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running.
Special note:
–OBD warning light illuminated.
Check the cleanliness and condition of the engine flywheel.
Repair or replace the engine flywheel if necessary.
If the flywheel has been replaced or removed, the flywheel ring has to be reinitialised, then reprogrammed.
Reinitialise programming:
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).
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair.

Electric coolant pump.
Check the cleanliness, condition and fitting of the coolant pump.
Top up the coolant if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any harness damage, and check the condition and connection points of the injection computer and the
coolant pump connectors.
Repair if necessary.
If the fault is still present, check for +12V on track 2 of the coolant pump.
If +12V is not present on track 2 of the coolant pump, check the following connection for insulation, continuity
and the absence of interference resistance:

Switching Unit
Repair if necessary.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connection:
Computer, connectorB, track L4 track 1 of the coolant pump
Repair if necessary.
If the fault is still present, check that the resistance between tracks 1 and 2 of the coolant pump is neither zero
nor infinite.
Replace the coolant pump if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.
