and the ET056 Double richness loop is ACTIVE.
– a smooth driving road test after the fan unit has been in operation, immediately
followed by a road test on a slope at no load (injection cut-off in the deceleration
phase).
Special note:
–OBD warning light illuminated.
Check the cleanliness and condition of the downstream oxygen sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Computer, connectorC, track B2 Track D of the downstream oxygen sensor
Computer, connectorC, track A2 Track C of the downstream oxygen sensor
Repair if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.

Deal with faults DF084 Actuator relay control circuit or DF046 Battery voltage first
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running.
Run a multiplex network test (see88B, Multiplex).
If the fault is still present, carry out fault finding on the automatic transmission system (seeMR 364, Mechanics,

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.
