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.

ACTUATOR STATIC TEST
NOTESThere must be no present or stored faults.
Switch the ignition on and run command AC079 Actuator static test.
If the following actuators are not working, apply the interpretation of the associated fault:
– 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
2 sensor heating, apply the interpretation of DF601 Upstream O2 sensor heating power circuit.
– Downstream O
2 sensor heating, apply the interpretation of DF602 Downstream O2 sensor heating power
circuit.
AFTER REPAIRRepeat the conformity check from the start.

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.
Replace the coolant pump if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.
