Fault finding - Replacement of components
COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
The system can be programmed or reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic
tool (see Technical Note 3585A).
While the computer is being reprogrammed the engine fan assemblies are automatically triggered).
Operations to be carried out before reprogramming the injection computer:
Before reprogramming the injection computer, move the main Cruise control/Speed limiter 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.
To reset the function, proceed as follows:
Vehicle ignition on.
– Position the main switch in rest position (the computer then detects the rest position).
– Position the switch in Cruise control position to activate the Cruise control function.
– Position the switch in Speed limiter position to activate the Speed Limiter function.
Before reprogramming or replacing the computer in After-Sales operations, backup the following data to the
diagnostic tool:
– The IMA codes (individual correction of the injector).
– The engine adaptives (engine speed, and options available on the vehicle).
(this file corresponds to 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,
with command SC003 Backup computer data. IMPORTANT
–Switch on the diagnostic tool (mains or cigarette lighter feed).
–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 below 60 °C and air temperature below 50 °C).
WARNING
A computer without the IMA option can be replaced by a computer with this option. The codes have
therefore not been backed up during command SC003.
In this case, status ET104 "Injector code use" becomes "YES" or "FAULTY", fault DF276 "Injector code
programming" is present, and the engine operates in defect mode.
In this case, run command SC002 Enter injector codes, applying the procedure described in the
interpretation of this command.
