Wiring check
Fault finding problems
Disconnecting the connectors and/or handling the wiring harness may temporarily remove, the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

NOTESConditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after the
fault has been cleared, the ignition switched off and back on again and the receiver
started with several actions.
Order of priority in the event of more than one fault:
If there is a combination of faults DF022 and DF027 "No audio CD changer signals",
check the multiplex network (see 88B, Multiplex).
Use the Wiring Diagrams Technical Note, Scenic II.
Check the condition and the connection of the receiver 32-track connector (component code 261), of the navigation
central control connector (component code 1657) and of the navigation computer 32-track connector (component
code 662) (broken, oxidised, bent tabs).
Manipulate the wiring harness at the connectors to produce a change in fault status (present → stored).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, wiring: Precautions for repair), repair the connector(s); otherwise, replace the wiring.
With ignition on, check for + 12 V on connection BCP3 of the 8-track connector on component 261.
Check that the earth on the MT connection of the 8-track connector on component 261 is perfect.
If any connection is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring; otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●connection code 107W,
●connection code 107X,
●connection code 34HU,
between components 1657 and 261.
If any connection is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
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 using command RZ001 Fault memory.
Deal with any other faults.
