Passenger Compartment Heating Resistor Management:
In order to reduce the time required to heat up the passenger compartment, the vehicle is fitted with Passenger
Compartment Heating resistors (RCH). These passenger compartment heating resistors are run and controlled by
the UCH. The injection computer authorises or prohibits the operation of the passenger compartment heating
resistors according to the operating phases and engine power needs.
Cruise control/speed limiter management:
The vehicle cruise control function, when activated, allows you to keep the vehicle speed at a selected value
regardless of the driving conditions encountered.
Using the control buttons, the driver can increase or reduce the speed of the vehicle.
If the driver wishes to exceed the cruising speed, he may:
–depress the accelerator pedal and exceed the cruising speed (the vehicle will return to the initial cruising speed
once the driver takes his foot off the pedal),
–press the system control buttons.
The cruise control function can be deselected either by:
–the system control buttons,
–deactivating the cruise control switch,
–when system events are detected, such as the brake pedal or clutch being depressed,
–when system errors are detected such as an inconsistent vehicle speed.
The cruise function can also be temporarily disabled when the driver wants to increase speed by depressing the
accelerator pedal. The cruising speed is resumed when the driver releases the accelerator pedal.
The vehicle will then attempt to reach the cruising speed at a controlled acceleration rate.
It is possible to reactivate the vehicle speed control and resume the last cruising speed after deactivation (computer
supply not cut off).
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 ignores the pedal request and controls the vehicle speed in
the same way as the cruise control function, provided that the driver keeps the accelerator pedal sufficiently
depressed.
Like the cruise control function, the limit speed can be modified by pressing or pressing and holding the control
buttons.
For safety reasons, it is possible to exceed the limit speed by depressing the accelerator pedal and exceeding the
pedal position limit value. The vehicle speed is then totally controlled as a function of pedal position until the speed
falls back below the limit speed when the speed limiter function will once again be reactivated.
If the driver wishes to exceed the cruising speed, he may:
–exceed the accelerator pedal's kickdown point,
–increase the limit speed by pressing or pressing and holding the limit speed switch.
The speed limiter function can be deselected either:
–the system control buttons,
–by switching off the speed limiter switch,
–when system events are detected, such as the brake pedal or clutch being depressed,
–when system errors are detected such as an inconsistent vehicle speed.

CRUISE CONTROL/SPEED LIMITER
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT DETECTEDIf the vehicle is not fitted with cruise control/speed limiter function buttons, status ET042
is permanently NOT DETECTED. This confirms that the cruise control/speed limiter
function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main switch
is in rest (or neutral) position and the injection computer has just been programmed or
reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the cruise
control position and then in the speed limiter position.
Return to rest position.
The tool displays status ET042: INACTIVE.
If not, several steps must be checked:
1 - Return to the page about testing the multiplex network with the CLIP program.
Repeat the multiplex network test. Re-establish dialogue with the injection computer.
Check status ET042. If ET042 is INACTIVE, the injection computer has detected the
various positions of the main switch. The cruise control/speed limiter is active.
2 - If status ET042 is still NOT DETECTED, check that the owner of the vehicle has not,
sometime in the past, asked for the cruise control/speed limiter function to be
deactivated. Contact the Techline.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

(CONTINUED 2)
STATUS 4
Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- Either the cruise control is active, or
- the speed limiter is active
- and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 4 without pressing the 0 button, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the steering wheel, to the right.
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the injection
computer receiving a signal indicating that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
- status ET042 Cruise control/Speed limiter,
- status ET703 Cruise control/speed limiter buttons,
- status ET704 Brake contact no. 1,
- and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 changes to STATUS 5, deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
is pressed. These buttons are located on the steering wheel.
If status ET703 does not display INACTIVE,
- check the condition of the cruise control/speed limiter “+/-” button and the condition of
its connector.
check the condition of the cruise control/speed limiter "R/0" button and the condition of
its connector.
INCREASEStatus ET703 becomes “PLUS” when the cruise control/speed limiter “+” button is
pressed. This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter “+/-” button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connections while pressing the + button
(on the button tracks):
●Connection code 86G, of component 331.
●Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection when
the button is in the rest position.
If there is continuity, replace the +/- control button.
If there is a repair method (See Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic tool
