present, then carry out this fault finding procedure.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check the condition and connection of the passenger's side front door external aerial connector (tabs bent,
broken, etc.).
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 condition and connection of the PE3 connector of the UCH (tabs bent, broken, etc.).
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 connections:
●Connection code 26AC,
●Connection code 26AD.
Between components 645 and 1375.
If the connection(s) 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 it.
If the fault is still present, contact the Techline.
