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.
Deal with any other faults.
Clear the stored faults.

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:
Coolant pump track 2 track 6, connector CN, of the Protection and
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:

NOTESSpecial notes:
If this fault appears during the engine starting phase, followed by a high idle speed
(warm engine), check the conformity of the alternator and its configuration in the UPC
according to the procedure below:
– Check that the part number of the alternator fitted on the vehicle conforms with the
part number in the World Vehicle Database.
– Using the CLIP tool, in the UPC field, check that the alternator's configuration CF001
Alternator type corresponds with the alternator fitted on the vehicle (and the World
Vehicle Database).
This last stage is only possible on first generation UPCs (in Vdiag 44). Second
generation UPCs (Vdiag 48 and higher) are self-configured.
Run a multiplex network test (see88B, Multiplex).
Disconnect the battery and the injection computer.

STOREDLPG CYLINDER 1 COMBUSTION MISFIRE
1.DEF: Destructive misfiring
2.DEF: Polluting misfiring
3.DEF: Non-compliance with emission control standards
NOTESPriority when dealing with a number of faults:
– LPG fuel system: see 17C, LPG injection,
– ignition:
DF361 Ignition coil circuit cylinders 1-4,
DF362 Ignition coil circuit cylinders 2-3.
– flywheel signal:
DF154 Flywheel signal sensor circuit,
DF457 Engine flywheel target.
Check whether there are other cylinders with an LPG combustion misfire fault detected
by the tool before starting the following fault finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– the programming must have been done, particularly the flywheel target,
– engine warm (min 75°C),
– run the engine at idle speed with all electrical consumers switched on for
approximately 15 minutes.
Special note:
– catalytic converter misfire: OBD warning light flashes when the fault is present then
is continuously lit,
– pollutant combustion misfire: OBD warning light lit continuously.
–engine unstable, loss of power and vibrations.
Misfiring on
cylinder 1 only
Combustion
misfires on
cylinders 1 and 4
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 1 LPG injector
If everything is in order, check the same components on cylinder 4 (to cover a possible
cylinder recognition error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply the interpretation of fault DF361
Ignition coil control 1-4 or DF362 Ignition coil control 2-3),
– check the condition and conformity of the spark plugs.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
