Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of the faults should be considered when the diagnostic tool is switched on after
the + after ignition feed is switched on (with no system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as defective,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because
the data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult
the corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
Customer complaints.
A synopsis of the general procedure to follow is provided on the following page in
the form of a flow chart.

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.

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.
