NOTESConditions for applying the fault finding procedure to a stored fault:
Activation of command AC037: Transmitter aerial fault finding; if the fault becomes
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 front internal 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 26AT,
●Connection code 26AU.
Between components 645 and 1396.
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.
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.
