Fault finding – Replacement of components
1. PROGRAMMING, REPROGRAMMING OR REPLACING THE COMPUTER
The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic
tool (Consult Technical Note 3585A or follow the instructions provided by the diagnostic tool).
Whenever the computer has been programmed, reprogrammed or replaced:
–switch off the ignition;
–start and then stop the engine (to initialise the computer) and wait for 30 seconds,
–switch on the ignition again and use the diagnostic tool to carry out the following steps:
– run command VP010 Enter VIN,
– deal with any faults declared by the diagnostic tool. Clear the computer memory.
– program the flywheel sensor target and throttle stops,
– carry out a road test followed by another check with the diagnostic tool.
2. REPLACING OR REMOVING THE TDC SENSOR
When the TDC sensor is replaced or removed, the flywheel target has to be programmed.
3. REPLACING THE MOTORISED THROTTLE VALVE
When the throttle valve is replaced, the throttle stops must be programmed.IMPORTANT
–switch on the diagnostic tool (mains or cigarette lighter supply),
–connect a battery charger (during the entire computer (re)programming procedure, the motor-driven fan
assemblies are triggered automatically),
–observe the engine temperature instructions of the diagnostic tool before (re)programming.
IMPORTANT
It is not possible to test an injection computer from the Parts Department because it can no longer be fitted on any
other vehicle.
IMPORTANT
Never drive the vehicle without having programmed the throttle stops.

– fuel supply system: DF026, DF027, DF028, DF029 and DF085.
– engine flywheel signal: DF005 and DF125.
Check whether other cylinders have misfiring faults before starting the following fault
finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– programming must be carried out.
– warm engine (minimum 75°C),
– idling with all the electrical consumers activated for 15 minutes.
Special note:
–OBD warning light illuminated.

Combustion
misfires in
cylinders 1 and 4
(see DF059
Combustion
misfires in
cylinder 1 and
DF062
Combustion
misfires in
cylinder 4)
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 injector
– check the condition and conformity of the spark plugs,
– check the cylinder 1 pencil coil.
If everything is in order, check the same components on cylinder 4 (to cover
a possible cylinder recognition error).
– Carry out the steps "according to the repair".
The fault is probably due to a component that affects a pair of cylinders:
– check the relevant ignition coil circuit (apply the fault finding procedure DF720
Ignition coil circuit 1 or DF075 Ignition coil circuit 4),
– check the condition and conformity of the spark plugs.
– Carry out the steps "according to the repair".
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
– there must be no further electrical faults,
– programming has been carried out,
– warm engine (minimum 75°C).
– running at idle speed with all electrical consumers drawing power for 15 minutes.
– if the fault is still absent, check that the catalytic converter is in good condition. Use
command SC006 Run OBD Test: Catalytic converter.
