After programming, reprogramming or replacing the computer:
–switch the ignition off and then on again,
–start and then stop the engine (to initialise the computer) and wait for 30 seconds,
–use the diagnostic tool to carry out the following procedures:
– run command SC001 Enter saved data, to re-establish the injector codes and engine adaptives,
– run command VP010 Enter VIN,
– deal with any faults declared by the diagnostic tool. Clear the computer memory.
– carry out a road test followed by another check with the diagnostic tool.
Note:
If commands SC001 and SC003, have been forgotten or do not work after replacing or (re)programming the
computer, enter the IMA codes for each injector manually by reading the code on each injector (see Replacement
of injectors).
IMPORTANT
– the injection computer retains the immobiliser code for life,
– the system has no security code,
– it is prohibited to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned,
– these computers are hard-coded,
– if the injection computer appears to be faulty, contact the Techline and refer to the fault finding log.

REPLACING THE INJECTORS
When one or more injectors are replaced, the IMA parameters of the injector output concerned must be modified.
The system can be configured with the diagnostic socket using the RENAULT CLIP diagnostic tool.
To do this, display the IMA code(s) etched on the injector bodies, and enter the codes into the computer using
command SC002 Enter injector codes, and follow the instructions given by the diagnostic tool.
REPLACING THE EXHAUST GAS RECIRCULATION VALVE
When replacing the exhaust gas recirculation valve, enter the operational values of the new valve into the computer.
After replacing the exhaust gas recirculation valve, select Clear mode on the diagnostic tool.
Run command RZ002 EGR adaptives.
When the command is completed, switch off the ignition and exit fault finding mode.
–wait 30 seconds, and switch on the ignition again,
– clear any faults,
– start the engine,
– let the engine idle for 1 min, accelerate to 2500 rpm for 5 s, and return to idle speed,
– repeat this procedure 5 times.
Check the faults:
If the fault does not recur, end of fault finding procedure.
If the fault recurs, restart the procedure after disconnecting and reconnecting the valve.
If the fault is still present, replace the EGR valve. Note:
The IMA coding (individual injector correction) is a calibration made in production on each injector to adjust
the flow accurately.
These correction values are etched on the Bakelite body of each injector (6 alphanumeric characters) and then
entered into the computer which then controls each injector taking into account their manufacturing variation.
IMPORTANT
When the command is complete, switch off the ignition and exit fault finding mode.
Wait 30 seconds.
Return to fault finding mode.
Select the Identify computer function from the main screen.
Check that the injector codes entered into the computer correspond to those on the injector bodies.
If the codes do not match, restart the command SC002 Enter injector codes procedure.
Then check the system faults, and clear any stored faults.
If the computer does not have any faults, the operation is complete.
If there are faults, deal with the present faults.
