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:
– press 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 pressed,
– when system errors are detected such as an inconsistent vehicle speed.
The cruise control function can also be temporarily disabled when the driver wants to increase speed by pressing
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
feed 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 depressed.
As with the cruise control function, the cruising speed can be altered using the control buttons by pressing briefly or
keeping the switch pressed.
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 cruising 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 pressed,
– when system errors are detected such as an inconsistent vehicle speed.

Sensor electrical conformity
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 and 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
For status ET042: the tool displays 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
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 vehicle's owner has not
had the cruise control/speed limiter function disabled in the past. Contact the
Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 3
Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is no longer coupled to
the engine (clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active
(ET042 Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is
depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed,
consult the interpretation of status ET405 Clutch pedal switch.
If the vehicle is fitted with an automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation
to the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing).
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, or
– the speed limiter is active
– and when the "0" button is pressed by the driver.
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 steering wheel, to the right.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise 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, consult the interpretation of statuses:
– ET042 Cruise control/speed limiter
– ET703 Cruise control/speed limiter buttons
– ET704 Brake switch No. 1
– 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 use the diagnostic tool to
check the presence of 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 faults present or stored in the
injection computer.
If the fault is still present, contact the Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6, when driving with cruise control active
(ET042: Cruise control/speed limiter: CRUISE CONTROL) and:
– if the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is put in neutral on an automatic transmission.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into the neutral position on an automatic
transmission, test the ABS computer and check the configuration of the tyre size
stored in the computer.
If the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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 frontal airbag (see MR 364 Mégane,
MR370 Scénic, Mechanical, 88C, Airbag and pretensioners, Driver's front
airbag, Removal - Refitting).
If status ET703 does not display INACTIVE,
– check the status of the cruise control/speed limiter +/- button and the condition of its
connector.
– check the status of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes INCREASE when the + button of the cruise control/speed
limiter is pressed. This button is on the steering wheel, on the left-hand side.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's frontal airbag (see MR 364 Mégane,
MR370 Scénic, Mechanical, 88C, Airbag and pretensioners, Driver's front
airbag, Removal - Refitting)
If status ET703 does not display INCREASE, check the status of the +/- button of the
cruise control/speed limiter and the status of its connector. Repair if necessary.
Measure the resistance on the following connections while pressing the +
button (on the button tracks):
– Connection code 86G of component 331.
– Connection code 86M of component 331.
