5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from Techline,
●for approval requests when replacing parts for which approval is mandatory,
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the proper tools. IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the multimedia system has been switched on using
the on/off button.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Check the battery voltage,
Check the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Check the condition of the multimedia network interface unit supply fuse.
If the supply fuse is correct, check for + 12 V on connection BCP4 (Kangoo 2), BCP4 (Trafic II ph2), BP3A
(Espace IV ph2) or BCP3 (Scénic II ph2).
If there is no + 12 V, check the continuity of connection BCP4 (Kangoo 2), BCP4 (Trafic II ph2),
BP3A (Espace IV ph2) or BCP3 (Scénic II ph2).
Check for earth on connection MAN (Kangoo 2), MAN (Trafic II ph2 and Scénic II ph2),
NC (Espace IV ph2).
If the connection is 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 the fuse is not correct, check the insulation against earth on connection BCP4 (Kangoo 2), BCP4 (Trafic II
ph2), BP3A (Espace IV ph2) or BCP3 (Scénic II ph2).
If the connection is 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 fuse.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other possible faults.
