COMPUTER REPLACEMENT, PROGRAMMING AND REPROGRAMMING OPERATIONS
Before reprogramming or removing the computer in After-Sales operations, save the following data to the
diagnostic tool:
– The C2I parameters (individual injector correction) and the engine adaptives using command SC003 Save
computer data.
The system can be reprogrammed with the diagnostic socket using the RENAULT CLIP diagnostic tool
(Consult Technical Note 3585A, Computer programming and reprogramming procedure, and follow the
instructions given by the diagnostic tool).
Any time the computer has been reprogrammed
– Use the diagnostic tool command SC001 Enter saved data to restore the C2I and the engine adaptives.
– Use command AC028 Static test to reinitialise the computer (fan assembly, etc.).
– When changing the pump, refer to the high pressure pump replacement procedure (consult Technical Note 5011A,
Repriming Delphi high pressure pumps on K9K engines).
– Switch the ignition off and then on again.
–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 on again 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. 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 Cruise control position to activate the Cruise control function.
Switch in Speed limiter position to activate the Speed limiter function.
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 below 60°C and air temperature below 50°C).

REPLACING THE INJECTORS:
The system may be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
The C2I parameters must be replaced after replacing an injector/injectors.
To do this, reprogram the C2I into the computer using the following commands:
Cylinder 1 injector: command VP001 Cylinder 1 injector code (cylinder at flywheel end).
Cylinder 2 injector: command VP002 Cylinder 2 injector code.
Cylinder 3 injector: command VP003 Cylinder 3 injector code.
Cylinder 4 injector: command VP004 Cylinder 4 injector code.
It is also possible to enter the four C2I using command SC002 Enter injector codes.
The technician can use the appropriate command to re-enter the new C2I for the replaced injector and to erase the
old C2I.
–Only after simultaneously replacing at least three injectors, reset the injector programming adaptives, using
command RZ004 Pressure regulation programming adaptives. IMPORTANT
AFTER A PROGRAMMING OPERATION, DO NOT CONNECT THE BATTERY FOR AT LEAST 30 minutes (to
carry out other work on the vehicle).
Note:
If commands SC001 and SC003 have been lost or if they are not operating after programming the computer:
– Enter the C2I for each injector manually, by reading the C2I on each injector (see Replacement of
components, Injector replacement).
– Use command AC028 Static test to reinitialise the computer (fan assembly, etc.).
– Switch the ignition off and then on again.
– Clear the engine management computer faults.
IMPORTANT
It is not possible to try an injection computer from the Parts Department as it will not be possible to fit it on another
vehicle afterwards.
Note:
C2I (individual injector correction) is a calibration carried out in the factory on each injector to adjust the flow
of each injector precisely.
The correction values are written on a label affixed to each injector, then entered in the computer which can then
actuate each injector by taking account of their manufacturing variation.

REPLACING THE HIGH PRESSURE PUMP
On a vehicle which is equipped with a computer with a Vdiag 44, always reprogram the injection computer
(see Replacement of components, Computer replacement, programming, or reprogramming operations),
then apply the procedure below.
This reprogramming will install new functions in the computer to enable the injection pump to be reprimed with
diesel without damaging it.
After reprogramming, Vdiag 44 is replaced by Vdiag 48.
On a vehicle fitted with a computer with Vdiag 48, apply the procedure below before starting the engine.
PROCEDURE
Refer to Technical Note 5011A, Repriming Delphi high pressure pumps on K9K engines.
EGR VALVE REPLACEMENT:
If the EGR valve is replaced, program the new valve's offset position. To do this, clear the old offset using the EGR
programming deletion procedure and run command RZ002 EGR valve adaptive. IMPORTANT:
When reprogramming the computer, only carry out the following procedure after command AC028 Static
test has been run (see Replacement of components, Computer reprogramming operation).
IMPORTANT:
Perform this procedure only if the valve is new.

SETTINGS
VP001: Cylinder 1 injector code.
VP002: Cylinder 2 injector code.
VP003: Cylinder 3 injector code.
VP004: Cylinder 4 injector code.
These commands enable you to manually write the calibration code inscribed on the injector. Use these commands
after replacing an injector or replacing or (re)programming the computer, when command SC001 does not work.
VP010: Enter VIN.
This command permits manual entry of the vehicle's VIN into the computer. Use this command each time
the computer is replaced or (re)programmed.
SPECIAL COMMANDS
SC001: Write saved data.
Use this command after replacing or (re)programming a computer (if the information was saved using SC003).
SC002: Enter injector codes.
This command enables you to manually write the calibration code inscribed on the injectors. Use this command after
replacing the injectors.
SC003: Save computer data.
This command saves the computer's operating data, the C2I (individual injector correction) parameters,
and the engine adaptives. Use this command before replacing or (re)programming the computer.
OTHER COMMANDS
LC005: Gearbox type. This command enables you to determine the gearbox type configured on the vehicle.
LC120: Cruise control. With or without
LC121: Speed limiter. With or without
