EGR PROGRAMMING CUT-OFF
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
NONE
No EGR cut-off, the EGR valve is working properly in accordance with the
computer programs.
Switch off the ignition and wait 1 minute.
Switch the ignition on and check for faults.
Check the engine battery voltage with the engine stopped and then running.
If no faults are present or stored, restart the vehicle and test at idle speed.
Do not accelerate too much and reach an engine speed that is too high.
Accelerate above idling speed for a few seconds.
Check that the clutch pedal (ET405 Clutch pedal switch) is not pressed and that the
vehicle has stopped completely.
Test the present and stored faults and repair.
Reinitialise the EGR offsets by consulting the interpretation of command
SC036 Reinitialisation of programming and select EGR valve".
Allow the engine to heat up until this cut-off disappears.
Check that the regeneration of the particle filter in progress has completely finished.
Allow the engine to cool until this cut-off disappears.
Too low atmospheric pressure, the EGR valve is disabled.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
is pressed. These buttons are located on the steering wheel.
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.
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 these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
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 300 Ω, check the continuity of the connection 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 the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic tool

DECREASEStatus ET703 becomes MINUS 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 change to MINUS, 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 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance of the following connection whilst 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 Ω, check the continuity of the connection 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 the wiring
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 364 (Mégane) or 370
(Scénic), Mechanical, 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
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 0Ω, 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 the wiring.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

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) or 370

●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,
