Fault finding – Replacement of components
COMPUTER REPLACEMENT OR REPROGRAMMING
Operations to be carried out before reprogramming the injection computer:
Before reprogramming the injection computer, move the main CC/SL switch to the rest position. The information
about the cruise control or the speed limiter displayed on the instrument panel disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
–Vehicle ignition on.
–Move the cruise control/speed limiter switch to the rest position (the computer detects the rest position at that
moment).
–Move the cruise control/speed limiter switch to the Cruise control position to activate the Cruise control function.
–Move the cruise control/speed limiter switch to the Speed limiter position to activate the Speed limiter function.
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
–Use SC003 before the computer is replaced or reprogrammed. This enables certain data to be saved in the
diagnostic tool so that the new computer* can be reconfigured like the old one. The saved data are: injector
codes, EGR programming, vehicle options.
–Run SC001 after the computer is replaced or reprogrammed. It enables you to rewrite the data (saved by
command SC003) to the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything. After
replacing the computer, enter the IMA code of each injector manually, reading the code on each injector (see
INJECTOR REPLACEMENT).
Exhaust gas recirculation valve data is programmed automatically the 1
st time the new computer is switched on*.
* new computer or reprogrammed computer. IMPORTANT
–Switch on the diagnostic tool (mains or cigarette lighter supply).
–Connect a battery charger.
–Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.).
–Wait for the engine to cool (engine coolant temperature < 60˚ and air temperature < 50˚).
–The GMV are activated automatically when the computer is being reprogrammed.

PROGRAM No: C1
Vdiag No.: 51
→ PROCEDURE:
●Before replacing or reprogramming the computer:
–Select SC003 Save computer data,
–if the following message appears: there is a saved file; do you want to overwrite this data?: (this file is the
last save carried out on the tool)
–select YES,
When the backup is complete, replace the computer or reprogram, then proceed to the next step.
●After replacing or reprogramming the computer:
–Select SC001 Write saved data, then follow the instructions given by the diagnostic tool,
–if the VIN is not entered (see Computer identification on the main screen),
–select VP010 Enter VIN,
When both these commands have finished:
–switch off the ignition and wait 1 minute before switching the ignition on again.
–then check the system faults, and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.IMPORTANT
–The injection computer retains the same immobiliser code for life.
–The system has no security code.
–It is forbidden 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
After replacing one or more injectors, re-enter the IMA codes.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
→ PROCEDURE to be followed after one or more injectors are replaced:
IMPORTANT
Cylinder no. 1 is located at the engine flywheel end.
–make a note of the IMA code(s) engraved on the injector body,
–enter these codes in the computer using command SC002 Enter injector codes, then follow the instructions given
by the diagnostic tool,
–once the command has finished,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–return to fault finding mode,
–select the Computer identification function from the main screen,
–check that the injector codes entered into the computer match those found on the bodies of the injectors:
–if the codes do not match, repeat the procedure for command SC002 Enter injector codes;
–if the codes do match, check system faults and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.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 onto 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
Engines can only operate correctly if the correct IMA codes have been entered.
If no code has been entered or if an invalid code has been entered, the fault DF276 Injector code
programming, is present and the engine will be in defect mode (speed heavily limited).
If another injector's code has been entered, the system will accept it but will make the wrong correction.
This could lead to engine damage, loss of performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.

REPLACING OR CLEANING THE EXHAUST GAS RECIRCULATION VALVE (EGR valve)
After the exhaust gas recirculation valve has been replaced or cleaned, the computer must store the new valve's
offset and the offset measured the last time the ignition was switched off, which is when the valve closed.
Using this data, the computer can detect whether the valve is clogged or seized.
When the valve is replaced or cleaned, clear the stored offsets so that the program uses the new valve's offset value.
The data linked to this program is compiled in the Emission control/OBD sub-function.
–PR128: First EGR valve offset.
–PR129: Last EGR valve offset or = PR128 for a new valve.
Programming PR128 and PR129 must be cleared every time the exhaust gas recirculation valve is replaced.
→ PROCEDURE:
–run command SC036 Reset programming;
–select EGR valve as the operation type then follow the instructions given by the diagnostic tool,
When the command is finished,
–switch off the ignition,
–wait 1 minute before switching on the ignition again.
When the ignition is next switched on again the new EGR valve offset is automatically reprogrammed.
–start the vehicle to enable the latest EGR valve offset to be programmed,
–switch off the ignition,
–wait 1 minute before switching on the ignition again.
The last EGR valve offset reprogrammed is stored on the computer.
–then check the system faults, and clear any stored faults;
–otherwise deal with faults which are present and clear the faults in the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.Note:
When the reinitialisation is completed, the Emission Control/OBD sub-function displays:
PR128 = PR129 > 100%
Note:
When the new EGR valve offset has been reprogrammed, the Emission control/OBD sub-function displays:
10% < PR128 < 40%
PR129 > 100%
Note:
When the last new EGR valve offset has been reprogrammed, theEmission control/OBDsub-function displays:
10% < PR128 < 40%
10% < PR129 < 40%

REPLACING THE DAMPER VALVE
After replacing the damper valve, reconfigure the computer.
The system must be configured via the diagnostic socket using the RENAULT CLIP tool.
→ PROCEDURE to be followed after the damper valve is replaced:
–switch on the ignition,
–establish dialogue with the injection computer,
–run command SC036 Reset programming;
–select Damper valve as the operation type then follow the instructions given by the diagnostic tool,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–check that PR420 Damper valve error counter = 0;
–then check the system faults, and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.
