4. FAULT FINDING PROCEDURE (continued)
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, 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 to another wire.
If a fault is detected, repair or replace the wiring harness.

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.

NOTESThere must be no present or stored faults.
Engine stopped, ignition on.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Check the permanent + supply fuse of component 1714.
Check the condition of the connectors of the components supplying the multimedia network interface unit
depending on the location of the fuse.
If the voltage is at minimum:
Check the battery and the charge circuit:
–Scénic II ph2 and Kangoo 2, see 87G, Engine compartment connection unit.
–Espace II ph2 and Trafic II ph2, see Technical Note 6014A, Checking the charging circuit.
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumers switched on.
Check the insulation, continuity and the absence of interference resistance of the following connections:
Scénic II ph2:
–connection code BCP3 between components 1714 and 260.
–connection code MAN between component 1714 and earth MAN.
Kangoo 2:
–connection code BCP4 between components 1714 and 260.
–connection code MAN between component 1714 and earth MAN.
Espace IV ph2:
–connection code BP3A between components 1714 and 260.
–connection code NC between component 1714 and earth NC.
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.
AFTER REPAIRRepeat the conformity check from the start.
