STATUS DEFINITIONINACTIVE: This status indicates that no button has been pressed.
INCREASE: This status indicates that the increase button is pressed.
DECREASE: This status indicates that the decrease button is pressed.
SUSPEND: This status indicates that the 0 is pressed.
RESUME: This status indicates that the R button is pressed.
Conformity check: Engine stopped, ignition on or engine running.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control/speed limiter buttons
are pressed. These buttons are located on the steering wheel.
To be able to remove the driver's airbag and carry out the measurements safely
(see 88C, Airbag and pretensioners).
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.
To be able to remove the driver's airbag and carry out the measurements safely
(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 of the button between connections 86M and 86G while
pressing on the + button.
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 (see MR 364 (Mégane II), MR 370

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 be able to remove the driver's airbag and carry out the measurements safely
(see 88C, Airbag and pretensioners).
If status ET703 does not display DECREASE, check the condition of the cruise control/
speed limiter
± 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 button between connections 86M and 86G while
pressing on the - button.
If the resistance is not approximately 100 Ω, check 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

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.
To be able to remove the driver's airbag and carry out the measurements safely
(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 button between connections 86M and 86G while
pressing on the 0 button.
If the resistance is not about 0 Ω, replace the R/0 control button (see MR 364 (Mégane
II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR

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.
To be able to remove the driver's airbag and carry out the measurements safely
(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.
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 button between connections 86M and 86G while
pressing on the R button.
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
