NOTESConditions for applying the fault finding procedure to a
stored fault:
If the fault becomes present after an action on the stalk, 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 PE2 connector of the UCH (tabs bent, broken, oxidised).
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 steering column control connector (tabs bent, broken, oxidised, 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 14 1B,
●Connection code 14 1K,
●Connection ode 14 1C,
●Connection code 141L,
●Connection code 14 1D,
●Connection code 14 1M,
●Connection code 14 1G,
●Connection code 14 1N,
●Connection code 14 1H,
●Connection code 14 1P.
Between components 645 and 1519.
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.
If these connections are sound, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
