CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVE
Status 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 the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna 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 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 the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
removal-refitting).
Measure the resistance of 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
when the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

– after a customer complaint (e.g. lack of power).
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C.
If no pressure is being applied to the pedal PR030 = 0%.
In the event of a fault, refer to the interpretation of fault DF008 Pedal potentiometer circuit gang 1 or DF009
Pedal potentiometer circuit gang 2.

– connection code 3LR,
– connection code 3LS,
– connection code 3LT,
– connection code 3LU,
– connection code3LW,
– connection code 3LV.

If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repairs), repair the wiring; otherwise replace the wiring.
Pedal sensor connected, vehicle ignition on and engine stopped:
– check the value of PR030:
0% no load,
100% full load,
138% full load after kickdown point on pedal.
– if the value is not correct, replace the pedal sensor.
