PRESENT
IMPACT DETECTED SIGNAL
NOTESFault finding procedure application conditions:
Only apply the procedure if the fault is present and if the vehicle does not start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from the
Airbag computer via the multiplex network.
As soon as the injection computer receives this signal, engine operation is inhibited
and the level 2 warning light is lit.
Use bornier Ele. 1681 for all operations on the injection computer connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs:
– clear the fault,
– switch off the ignition and wait 30 seconds,
– wait for the engine immobiliser indicator light to flash,
– switch on the ignition,
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, carry out fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident, carry out fault finding on the Airbag computer.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

ET703
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.

AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

(CONTINUED 1)
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

Removal - Refitting).
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,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

Try to start communication with another computer on the same vehicle.
1)If dialogue is established with another computer on the same vehicle:
Contact Techline.
2)If dialogue is not established with any other computer on the same vehicle:
It may be that a faulty computer is causing interference on the multiplex network.
To locate it, carry out a process of elimination, disconnecting in turn all the computers linked to these lines
(according to wiring diagram and equipment): Airbag, ABS, UCH, instrument panel.
Try to establish dialogue after disconnecting each line:
If after disconnection:
– dialogue is successful: carry out the computer fault finding procedure and reconnect all the disconnected
components,
– it is not possible to establish dialogue: contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
