INACTIVE
MEGANE II:
When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main switch being in
the rest (or neutral) position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for +12 V after ignition on the switch connector.
– Connection code AP43 of component 1081.
Disconnect the main switch, and when it is in the rest position, check the insulation
between:
– Connection codes AP43 and 3FX, of component 1081.
– Connection codes AP43 and 3PD of component 1081.
Check the continuity between connections AP43 and 3PD of component 1081 in
the speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081 in
the cruise control position.
If these checks are not in order, replace the switch.
Check the continuity, insulation and the absence of interference resistance on
the following connections:
– Connection code 3FX,
– Connection code 3PD,
between components 1081 and 120.
Also check the engine management computer connectors.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET077IMPACT DETECTED
STATUS DEFINITIONNO: This status indicates that the airbag computer has not detected an impact.
YES: This status indicates that the airbag computer has detected an impact.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
This signal is transmitted by the airbag computer via the multiplex network.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
NOThe status is usually NO as no impact has been detected.
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).
YESIf the vehicle has had an accident, the injection computer receives the impact signal
via the multiplex network and may switch off the ignition. Status ET077 is YES.
Switch off the ignition for 10 seconds, then switch it back on, so the engine can be
restarted.
Clear the faults (even if no fault is present or stored).
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).

ET238SYNCHRONISATION
STATUS DEFINITIONSynchronisation is carried out during the engine starting phase. The camshaft position
sensor and the TDC sensor are synchronised. Once this synchronisation has been
carried out, it enables the computer to identify cylinder n°1 and to ascertain the precise
position of the cylinder's top dead centre.
Synchronisation also allows the computer to determine the injection strategy.
NOTESSpecial notes:
Only perform these 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
COMPLETEDStatus ET238 is DONE when the engine is started. The computer has identified
cylinder no. 1 and has identified the exact top dead centre position. Injection phasing
and engine management are now possible, and the engine should be working
properly.
NOT
PERFORMEDStatus ET238 is NOT COMPLETED if the engine has been stopped with the + after
ignition on.
If status ET238 remains NOT COMPLETED after an attempted start, consult the
interpretation of fault DF195 Camshaft sensor/engine speed consistency.
