COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
Before removing any old computer as an After-Sales operation, save the following data using the diagnostic
tool:
–The C2I (individual injector correction) parameters and the engine adaptives using command SC003 Save
computer data.
The system can be programmed by the diagnostic socket using the RENAULT CLIP diagnostic tool (refer to
Technical Note 3585A, Computer programming and reprogramming procedure, and follow the instructions
provided by the diagnostic tool).
After replacing or reprogramming the computer
–Switch the ignition off and then on again.
–Use the diagnostic tool command SC001 Enter saved data to restore the C2I and the engine adaptives.
–On Kangoo 2, use the diagnostic tool command SC040 Speed limiter, if necessary.
–Use command AC028 Static test to reinitialise the computer (fan assembly, etc.).
–Switch the ignition off and then on again.
–When changing the pump, refer to the high pressure pump replacement procedure (consult Technical Note
5011A, Repriming Delphi high pressure pumps on K9K engines).
–Activate the starter without releasing the key until the engine starts (the engine start time can be up to
20 seconds).
–Stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
–Run command VP010 Enter VIN.
–After injection system programming, stored faults may appear on other computers. Clear the memory of these
computers.
–Switch the ignition off and then on again. 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 less than 60
°C and air temperature less than 50°C).
IMPORTANT
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.
The procedure for resetting the function is as follows:
Vehicle ignition on.
Main switch in rest position (the computer then detects the rest position).
Switch in the Cruise control position to activate the Cruise control function.
Switch in the Speed limiter position to activate the Speed limiter function.
IMPORTANT
AFTER A PROGRAMMING OPERATION, DO NOT CONNECT THE BATTERY FOR AT LEAST 30 minutes (to
carry out other work on the vehicle).
