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.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer, connectorC, track E1petrol vapour absorber track 2
Repair if necessary.
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.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running and a road speed above 36 mph
(60 km/h).
Special note:
The acquisition is made if the vehicle is not fitted with an automatic transmission.
Check the cleanliness, condition and assembly of the clutch pedal switch and its connections.
Repair if necessary.
If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is active,
and that when the clutch pedal is released, that the switch is not active and that the recommendations regarding
clutch pedal clearance are still valid (see MR 364, Mechanics,20A, Clutch
Replace the switch if necessary.
If the fault is still present, manipulate the harness so that the status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and clutch pedal switch connectors.
Repair if necessary.
If the fault is still present, check the earth on track 2 of the switch.
