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.

NOTESSwitch on the + after ignition feed to enter fault finding mode with the computer.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2,
Trafic II ph2 or Kangoo 2.
Try the diagnostic tool on another vehicle.
Is it possible to establish dialogue with another computer?
YES NO
On the defective vehicle.
Check the battery voltage.
Check the condition and
connection of the battery
connections.
Check the condition of the fuses.
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 (wiring in good condition).
AFTER REPAIRCarry out a complete check with the diagnostic tool.
