Cruise control - speed limiter (CC / SL) 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 reduce the speed of the vehicle.
The cruise control function can be deactivated either using the control buttons, or by switching off the cruise control
function selector switch or when system events are detected such as the brake or clutch pedal being depressed,
or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle deceleration.
The cruise control function can also be temporarily overridden when the driver wants to resume control of
the vehicle and exceed the selected cruising speed by pressing the accelerator pedal, which causes the controlled
fuel flow to be exceeded. The cruising speed is resumed when the driver releases the accelerator pedal.
It is possible to reactivate cruise control and to return to the last cruising speed after the function has been
deactivated for whatever reason, during the same cycle of use (computer supply voltage not cut off). The vehicle will
then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When activated (using the selection switch), the vehicle speed limiter function limits the vehicle speed to
a preselected 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 limit the vehicle speed,
provided that the driver continues to depress the accelerator pedal.
As with the cruise control function, the limit speed can be altered using the control buttons by pressing briefly or by
pressing and holding (pressing and holding not active on Kangoo 2).
For safety reasons, the limit speed can be exceeded by depressing the accelerator pedal beyond the pedal position
limit value. The vehicle speed will then be totally controlled by the pedal until the speed falls back below the cruising
speed when the speed limiter function will once again be reactivated.
The driver has the following controls for the cruise control - speed limiter function:
–accelerator pedal,
–brake pedal,
–clutch pedal (not for sequential gearbox),
–function selector switch, used to select cruise control or speed limiter operating mode,
–activation switch on the steering wheel,
–required speed adjustment switch on the steering wheel.

Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This covers five
functions: the OBD warning light for European On Board Diagnostics (EOBD), pre-postheating, coolant temperature,
and Level 1 (non critical fault) and Level 2 (emergency stop) engine faults. These five functions are represented by
five warning lights or messages displayed by the trip computer.
Pre-postheating warning light
This warning light indicates that preheating is active.
Engine coolant temperature warning light
This warning light is used as an engine overheating indicator.
–In the event of overheating, it is up to the driver whether to stop the vehicle or continue driving.
OBD warning light
The OBD fault warning light is used to warn the driver of the presence of injection faults producing excessive
pollution or that the EOBD system is deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three consecutive
driving cycles.
The visual check of the warning light when the power is switched on (automatic test procedure managed by
the instrument panel) is carried out by the injection computer. It lasts 3 seconds or until the engine starts for
the New Twingo and Kangoo 2.
If a confirmed OBD fault causes the OBD warning light to come on, there should be no flashing after the warning
light illumination test. The instrument panel will also display the message: Check emission control.
The gearbox computer, if fitted, may also request the illumination of this warning light.
Level 1 warning
If there is a minor fault, the computer may request a level 1 warning to be displayed. Usually, the instrument panel
switches on the SERVICE warning light and sends out a "Check the injection" message. Refer to the operation of the
instrument panel (see 83A, instrument panel). Note:
This warning light comes on only if the vehicle is EOBD approved.
Note:
The SERVICE warning light will come on if the instrument panel is configured as cruise control - speed
limiter present, but the function has not yet been detected by the injection computer.

High and low pressure pump:
The pump draws in fuel from the tank, which passes through a fuel filter and supplies the fuel injectors.
Injector rail:
The injector rail receives and redistributes fuel under high pressure to the injectors.
Solenoid injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.
Catalytic converter:
Its role is to convert pollutant gases into harmless gases.
Heater plugs:
The heater plugs create a hot point in the combustion chamber to improve starting in low temperature conditions.
They are also used to improve idle speed stability under some conditions.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Turbocharger control solenoid valve (K9K 724, 766, 802, and 812 only):
This solenoid valve controls the turbocharger wastegate.
Air flowmeter (if present on the vehicle):
The flowmeter measures the amount of fresh air which goes back into the engine.
EGR valve:
The exhaust gas recirculation enables nitrogen oxide (NOx) emissions to be reduced significantly.
Cruise control - speed limiter on - off switch:
This switch turns the cruise control/speed limiter on or off.
Accelerator pedal potentiometer:
The accelerator potentiometer informs the computer about the position of the accelerator pedal (engine load).
Clutch pedal switch:
The clutch pedal switch informs the computer about the pedal status.
TDC sensor:
The angular position is measured using a magneto-inductive sensor triggered by machined teeth on the flywheel.
This sensor gives the engine speed as well as the position of the crankshaft for injection.
Camshaft sensor:
This sensor gives a signal to perform the injection cycle.
When the piston of cylinder 1 is at top dead centre (TDC), it can be either at the end of the compression stroke
or at the end of the exhaust stroke. The camshaft sensor enables a distinction to be made between these two states.
Refrigerant pressure sensor:
Its role is to measure the refrigerant pressure in the air conditioning circuit.
Engine coolant temperature sensor:
The engine coolant temperature sensor informs the computer about the engine coolant temperature.
Water in diesel fuel sensor (New Twingo and Kangoo 2 only):
This sensor determines if there is water present in the diesel fuel.

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).
