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 + after ignition feed is activated,
–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.
Look for any damage to the wiring harness, check the condition and connection of the connectors on
components 261, 1714 and 1127.
Manipulate the wiring harness in order to observe a change in the fault status (present → stored).
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance of the following connection:
–connection code 34HU between components 261, 1714 and 1127.
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 fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other possible faults.
