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
When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the driving
conditions encountered.
If the driver wishes to exceed the cruising speed, they may:
– depress the accelerator pedal and exceed the cruising speed (the vehicle will return to the initial
cruising speed once the driver takes their 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.
It is possible to reactivate the vehicle speed control and resume the last cruising speed after deactivation (computer
supply not cut off).
The vehicle speed limiter function enables, when it is active (switch turned on), the vehicle speed to be limited to
a preselected value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit
speed is reached.
If the driver wishes to exceed the cruising speed, they 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:
– by using 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
STATUS DEFINITION
NOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off
switch is in the rest (or neutral) position.
SPEED LIMITER: This status indicates that the driver has used the main switch to
select the speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT
DETECTED
If the vehicle does not have cruise control or 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 the 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 multiplex network test page on the Clip application. 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 activated.
2 If ET042 is 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 REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

ET415
(CONTINUED 2)
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button is
pressed.
Status ET415 becomes STATUS 4, when driving when:
- Either the cruise control is active.
- 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 RZ001
Fault memory.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.
STATUS 5Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the injection
computer receiving a signal 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,
- of status ET703 Cruise control / speed limiter buttons,
- of status ET704 Brake switch no. 1,
- of status ET705 Brake switch 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 with the diagnostic tool for
a fault connected with this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
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 the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
are pressed. These buttons are located on the steering wheel.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane II) or 372
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
Removal - Refitting).
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.
Repair if necessary.
INCREASEStatus ET703 becomes INCREASE 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 INCREASE, 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 372
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting)
Measure the resistance on the following connections while pressing the + button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection for
the button 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 it.
