INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control / speed limiter
buttons is pressed. These buttons are located on the steering wheel.
To carry out the checks and measurements in complete safety, observe the driver's
frontal airbag removal recommendations (see MR 392 (Clio III), MR 385 (Modus),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 88C, Airbag and
pretensioners, Driver's frontal 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,
If the connector(s) is faulty and if there is a repair procedure (see Technical Note
6015A, Repairing electrical wiring, Wiring: Precautions for repair), repair the
connector, otherwise replace the wiring.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
