NOTESConditions for applying the fault finding procedure to a stored fault:
Activation of command AC037: Transmitter aerial diagnostic; if the fault appears,
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 driver's side 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 the continuity of the following connections:
●Connection code 26AA,
●Connection code 26AB,
●Connection code 26AH,
●Connection code 26AG.
Between components:
–645 and 1374,
–645 and 1376.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Disconnect one aerial then the other to identify which is the cause of the fault.
(The aerials are connected by side, a short circuit in one aerial affects all the aerials on the same side).
Replace the aerial if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
