Wiring check
Fault finding problems
Disconnecting the connectors and/or handling the wiring harness may temporarily remove the cause of a fault and
create other faults.
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.
Continuity and insulation 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.

NOTESNone.
Try the diagnostic tool on another vehicle.
Check:
– the connection between the diagnostic tool and the diagnostic sensor (wiring in good condition),
– the connection between the diagnostic sensor and the diagnostic socket (lead in good condition),
– the engine and passenger compartment fuses.
Check for + 12 V battery on track 16, and + 12 V after ignition feed on track 1 and an earth on track 5 and on
track 4 of the diagnostic socket.
Repair if necessary.
Disconnect the automatic or electronic parking brake computer connector to check the insulation, continuity
and absence of interference resistance on the following connections:
Automatic parking brake computer connector
track H4
(except Laguna II, Vel Satis and Espace IV) track G4 + 12 V
track H2
(except Laguna II, Vel Satis and Espace IV) track G2 earth
track A4 track 7 of the diagnostic socket (K line)
Repair if necessary (see the vehicle wiring diagram).
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.
