Reinitialising the programming:
Run command RZ005.
Torque meter programming:
Accelerate up to 4000 rpm in third gear then decelerate at no load to power take-up speed*.
Then repeat immediately.
In rare cases, fault DF125 may appear.
(*This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque)

1.DEF : petrol circuit fault
NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with faults DF081 Solenoid valve canister bleed and
DF085 Fuel pump relay first if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after an attempt is made to start the engine.
Special note:
–OBD warning light comes on.
Check the cleanliness, condition and fitting of the fuel vapour absorber.
Repair if necessary.
If the fault is still present, adjust the harness so that the fault status changes (present stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and fuel vapour absorber connectors.
Repair if necessary.
If the fault is still present, check for the +12V on track 1 of the fuel vapour absorber.
If the +12V is not present, check the following connection for insulation, continuity and the absence of
interference resistance:
Fuel vapour absorber track 1 track 2 of connector PPM1 on the Protection and Switching Unit
Repair if necessary.
If the fault is still present, disconnect the battery and the injection computer.

If the fault is still present, measure the resistance between tracks 1 and 2 of the fuel vapour absorber bleed
solenoid valve.
Replace the bleed solenoid valve for the fuel vapour absorber if the resistance is not 26 ±4 at 23 °C.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connections:
Computer, connectorC, track D1 track 1 of the PEM connector of the Protection
and Switching Unit
Repair if necessary.
If the fault is still present, deal with the other faults, then proceed to the conformity check.

Misfiring on
cylinder 1 only
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 pencil coil,
