Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Statuses ET704 and ET705 should change status at the same time. If they are inconsistent, consult the
interpretation of fault DF228 Brake signal.
ACTIVE
or
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
Brake light switch, track 3 Injection computer, connector A,
black, 32-track track E4
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
Continuity between
tracksInsulation between
tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(brake pedal pressed)1 and 2 3 and 4
Replace the switch if the values obtained are not correct.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESThere must be no present or stored faults.
Without electrical consumers (radio, air conditioning, fan assemblies,
headlights, etc.).
Ignition on
Then at idle speed
If the voltage is at minimum:
Check the battery and the charging circuit (see Technical Note 6014A Checking the
charging circuit).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumer
(seeTechnical Note 6014A Checking the charging circuit).

Replace the downstream oxygen sensor.
If the fault is still present, the catalytic converter is certainly damaged.
If the catalytic converter is defective, determine the cause of the destruction, otherwise the new catalytic
converter may be damaged in turn.
Remove the catalytic converter.
Various things may destroy a catalytic converter:
–deformation (impact),
–thermal shock (cold water splashed onto a hot catalytic converter can damage it),
–defective injector or ignition: the catalytic converter is damaged by contact with fuel (coil fault, coil control fault,
injector jammed open),
–injector leak,
–abnormal oil or coolant consumption (defective cylinder head gasket),
–use of a fuel additive or other equivalent product (obtain information from the customer because this type of
product can contaminate the catalytic converter and render it useless sooner or later).
Look up the service history of the vehicle or, if this is not possible, ask the customer if the vehicle has had injection
or ignition faults.
If the cause of the catalytic converter damage has been found and the fault has disappeared, replace the
catalytic converter.
AFTER REPAIRRepeat the conformity check from the start.

CANISTER BLEED SOLENOID VALVE
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the fuel vapour absorber bleed solenoid valve connections.
Repair if necessary.
Measure the resistance of the petrol vapour absorber bleed solenoid valve.
Replace the bleed solenoid valve for the fuel vapour absorber if the resistance is not 26Ω ±4Ω at 23 °C.
Check for + 12 V feed on track 1 of the fuel vapour absorber bleed solenoid valve with the ignition on.
If +12V is not present:
– using the Universal bornier, check for continuity on the following connections:
Fuel computer, connectorB, track M2 track 1 of the petrol vapour absorber bleed
solenoid valve
Main relaytrack 1 of the petrol vapour absorber bleed
solenoid valve
Repair if necessary.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Using the Universal bornier, check the insulation and continuity of the following connection:
Petrol computer, connector C, track E1 track 2 of the fuel vapour absorber bleed
solenoid valve
Repair if necessary.
If the fault is still present, replace the solenoid valve.
AFTER REPAIRRepeat the conformity check from the start.

– Fuel pump relay, apply the interpretation of DF085 Fuel pump relay circuit.
– The motorised throttle, apply the interpretation of DF079 Motorised throttle valve servo control.
– The electric coolant pump, apply the interpretation of DF570 Coolant pump relay.
–Upstream O

ELECTRIC COOLANT PUMP
NOTESThere must be no present or stored faults.
Switch on the ignition and run command AC027 Motorised throttle.
If the coolant pump is not working.
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:
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:
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.
