NOTESConditions for applying the fault finding procedure to a stored fault:
Lock the vehicle and place your hand in each handle.
If the fault appears, carry out this fault finding procedure.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check that ET054 Optical sensors supplied is YES. If status ET054 remains NO, consult the interpretation of
status ET054.
Check the statuses of the sensors to determine which sensor is in short circuit: without a hand being placed inside
the handles, the statuses must be INACTIVE.
ET055 Driver's side optical sensor,
ET056 Driver's rear optical sensor,
ET057 Front/rear passenger optical sensor.
If one of the statuses remains ACTIVE, disconnect the faulty sensor(s): if, after disconnection, the status returns
to INACTIVE, replace the faulty sensor.
If a status remains INACTIVE after placing a hand inside the handle:
Check for + 12 V on connection 26BH of the sensor(s).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the insulation and continuity of the following connection:
●Connection code 26P between components 645 and 1084.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the insulation and continuity of the following connection:
●Connection code 26P between components 645 and 1086.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
