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).

REPLACING THE INJECTORS:
The system can be set up using the diagnostic socket with the RENAULT CLIP diagnostic tool.
The C2I parameters must be replaced after replacing an injector or injectors.
To do this, reprogram 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
The four C2I can be entered 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 adaptives, using command RZ004
Pressure regulation adaptives.
REPLACING THE HIGH PRESSURE PUMP
PROCEDURE
Refer to Technical Note 5011A, Repriming Delphi high pressure pumps on K9K engines.
EGR VALVE REPLACEMENT:
If replacing the EGR valve, it is essential to program the new valve's offset position. To do this, clear the old offset
using the EGR programming clearing procedure and run command RZ002 EGR adaptives. 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 and then are entered in the computer, which
can then actuate each injector by taking account of their manufacturing variation.
IMPORTANT
When reprogramming the computer, only carry out the following procedure after command AC028 Static
test has been run (see Computer reprogramming operation).

13B-154
AFTER REPAIRDeal with any faults. Clear the faults from the computer memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

ET415CRUISE CONTROL/SPEED LIMITER DEACTIVATION
STATUS DEFINITIONThis status varies according to engine specifications.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various reasons for 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 RZ001 "Fault memory" to reset this status to "NONE".
Conformity check: Engine stopped, ignition on or engine running.
WITHOUTThis status is present on the diagnostic tool when:
–the computer has been reinitialised.
–the computer has been reprogrammed.
STATUS 1Traction 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 the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
braking system).

In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
–The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
–Cleaning with a high pressure jet is forbidden.
Is there coolant present? Follow the recommendations below.
Is the solenoid valve subjected to significant fluctuations
or impacts?
Instructions:
–The solenoid valve must be correctly secured to its
mounting.
Contact with the engine environment is forbidden.Follow the recommendations below.
Check the turbocharger regulation control (no partial jamming, etc.).
Does the turbocharger control work? Carry out the necessary repairs.
