REQUEST TO START COMPRESSOR
ACTIVEThe air conditioning request has been made by the driver when pressing one of the air
conditioning controls (Auto, or AC).
Status ET088 becomes ACTIVE and the computer authorises or does not authorise air
conditioning depending on the operating conditions.
If status ET088 does not become ACTIVE after pressing the control button (See 62A, Air
conditioning).
INACTIVE
When the driver deactivates the air conditioning, status ET088 must become INACTIVE.
If this does not happen, (See 62A, Air conditioning).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

CLUTCH PEDAL SWITCH
STATUS
DEFINITIONACTIVE: This status indicates that the clutch pedal is depressed.
INACTIVE: This status indicates that the clutch pedal is released.
NOTESSpecial note:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
ACTIVEClutch pedal depressed.
Non-conformity of the brake signals and or the clutch switch signals can cause the
engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.
INACTIVEClutch pedal released.
Non-conformity of the brake signals and or the clutch switch signals can cause the
engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.
Sensor electrical conformity
ACTIVECheck the condition and fitting of the clutch pedal switch.
Remove the clutch pedal switch then check the insulation between tracks 1 and 2, with
the switch in the rest position.
Repeat this operation with the switch depressed and check the continuity between
tracks 1 and 2.
If these two checks are not in order, replace the switch.
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.

Remove the clutch pedal switch, check the insulation between tracks 1 and 2 in rest
position.
Repeat this operation with the switch pressed and check the continuity between tracks
1 and 2.
If these two checks are not in order, replace the switch.
Then check the continuity and absence of interference resistance of the following
connection:
Injection computer black 32-track
connector A, track C4Track 1 clutch connector
Check for earth on track 2 of the clutch switch connector.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any other faults. Clear the fault memory.

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.

DECREASEStatus ET703 becomes DECREASE 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 DECREASE, 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 II) or 370
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
Removal - Refitting).
Measure the resistance of the following connection whilst pressing the "-" button
(on the button tracks):
– Connection code86G of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 100 Ω, check the continuity of the button in 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.
SUSPENDStatus ET703 becomes SUSPEND when the cruise control/speed limiter 0 button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to SUSPEND, check the condition of the cruise control/
speed limiter R/0 button, and the condition of its connector.
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 370
(Scénic II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
Removal - Refitting).
Measure the resistance of the following connection whilst pressing the 0 button
(on the button tracks):
– Connection code86G 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.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

RESUMEStatus ET703 becomes RESUME when the cruise control/speed limiter R button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not become RESUME, check the condition of the cruise control/
speed limiter R/0 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 II) or 370

Measure the resistance on the following connection while pressing the R button
(on the button tracks):
– Connection code86G 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 in the rest position.
If there is continuity, replace the R/0 control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
