Cruise control/speed limiter management:
When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the driving
conditions encountered. Using the control buttons, the driver can increase or decrease the vehicle speed.
The cruise control function can be deactivated either by using the control buttons or by switching off the cruise
control function selection switch, or when system events are detected such as depressing the brake or clutch
pedals, or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle
deceleration. The cruise control function can also be temporarily suspended when the driver wants to resume
control of the vehicle and exceed the selected cruising speed by depressing the accelerator pedal which then
exceeds the selected fuel flow. The cruising speed is resumed when the driver releases the accelerator pedal.
The cruise control function can be reactivated and the last cruising speed can be resumed after deactivating
the function for whatever reason until the vehicle ignition is switched off (i.e. for as long as computer supply not cut
off). The vehicle will then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When switched on (using the selection switch), the vehicle speed limiter function limits the vehicle speed to a preset
value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached.
If an attempt is made to exceed this speed, the system will ignore the pedal request and will control the vehicle
speed as the cruise control function would do, provided that the driver continues to press the accelerator pedal.
As with the cruise control function, the set speed can be altered by adjusting the control buttons, with single touches
or holding down.
For safety reasons, the cruising speed can be exceeded by depressing the accelerator pedal beyond the pedal
position limiting value. Vehicle speed is then controlled using the accelerator pedal until the vehicle speed is
decreased to below the cruising speed, when the limiter function is activated again.
The driver has the following controls for the cruise control/speed limiter function:
– accelerator pedal,
– brake pedal,
– clutch pedal,
– function selector switch, used to select cruise control or speed limiter operating mode.
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This concerns 5
functions: the MIL (Malfunction Indicator Lamp) of the EOBD (European On Board Diagnostic), pre-postheating,
the coolant temperature, and engine faults: Level 1 (non-critical fault) and Level 2 (emergency stop). These five
functions are represented by 3 warning lights or messages displayed by the on-board computer.
Pre-postheating warning light
This light is used both as an in-operation indicator light and as a system fault indicator:
– permanently lit during + after ignition feed: indicates preheating of the heater plugs.
After preheating and an automatic timed 3 second off period, the warning light will come on if a Level 1 fault occurs
(leading to reduced operation and reduced safety levels. The driver should have repairs carried out as soon as
possible.)

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).

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
