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.

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.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial note:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various things that cause deactivation of the cruise control/speed limiter function, due to a
driver request or the external environment (e.g. STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ007 Fault memory, to reset this status to WITHOUT.
NONE
This status is present on the diagnostic tool when:
The computer has been reinitialised,
The computer has been reprogrammed.
Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving, with cruise control active (ET042:
Cruise control/Speed limiter: CRUISE CONTROL) and upon a traction control
request.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 1 without a traction control request (see 38C, ABS).
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
