CONTINUED 1
INCREASE
Status ET703 becomes PLUS when the cruise control / speed limiter + button is
pressed. This button is on the steering wheel, on the left-hand side.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
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.
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 Ωcheck the continuity of the connection
when the button is not pressed. If there is continuity, replace the +/- control button.
(see MR 364 (Mégane II), MR 370 (Scénic II), Mechanical, 83D, Cruise control,
Steering wheel switch: Removal - Refitting).
DECREASEStatus ET703 becomes DECREASE when the - button of the cruise control/speed
limiter is pressed. This button is on the steering wheel, on the left-hand side.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
If status ET703 does not change to MINUS, check the condition of the cruise control
/ speed limiter +/- button, and the condition of its connector. Repair if necessary.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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 100 Ωcheck the continuity of the connection
when the button is not pressed. If there is continuity, replace the +/- control button.
(see MR 364 (Mégane II), MR 370 (Scénic II), Mechanical, 83D, Cruise control,
Steering wheel switch: Removal - Refitting).

SUSPEND
Status ET703 becomes SUSPEND when the cruise control / speed limiter 0 button is
pressed. This button is located on the steering wheel, to the right.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
If status ET703 does not become SUSPEND, check the condition of the cruise control
- speed limiter R/0 button and the condition of its connector.
If there is a repair method (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 continuity, replace the R/0 control button (see MR 364 (Mégane II), MR 370
(Scénic II), Mechanical, 83D, Cruise control, Steering wheel switch: Removal -
Refitting).

RESUME
Status ET703 becomes RESUME when the R button of the cruise control/speed
limiter is pressed. This button is located on the steering wheel, to the right.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
If status ET703 does not change to RESUME, check the condition of the cruise
control / speed limiter R/0 button, and the condition of its connector. Repair if
necessary.
If there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
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
(see MR 364 (Mégane II), MR 370 (Scénic II), Mechanical, 83D, Cruise control,
Steering wheel switch: Removal - Refitting).
