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 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.
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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

If status ET703 does not display DECREASE, check the status of the +/- button of the
cruise control/speed limiter and the status of its connector. Repair if necessary.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the wiring, otherwise replace it.
Measure the resistance of the following connection whilst pressing the - button
(on the button tracks):
– Connection code 86G of component 331.

If there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the wiring, otherwise replace it.
Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
– Connection code 86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 0 Ω, replace the R/0 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.
Measure the resistance on the following connection while pressing the R button
(on the button tracks):
– Connection code 86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 900 Ω check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the R/0 control button.
