Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating 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.
Tactile inspection
While manipulating the wiring harness, 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.

Fault finding - Role of components
The system comprises the following components, according to whether or not it features the deadlocking function:
Electric central door locking:
Electric central door locking is operated using the locking button.
Tailgate lock: The electric tailgate lock is also used to open the tailgate. The tailgate locking and unlocking
function is controlled by the UCH.
Transponder and radiofrequency key:
–The transponder in the key enables the following signals to be sent to the UCH:
–Key identifier signal.
–Immobiliser code signal.
–The key radiofrequency (for top of the range vehicles) enables the key identifier to be transmitted
when the button is pressed. A radiofrequency wave is sent to the UCH to perform the user's request if the
key is allocated to the vehicle (opening the doors and the tailgate).
One touch window/anti-pinch module:
–One-touch window: the window is raised by pulling the button up and it is lowered by pressing down on
the button; pressing the button again has no effect on the initial operation.
–Anti-pinch: if an object prevents the window from closing, the anti-pinch function triggers the window to
be lowered by 50 mm. Access - ProtectionWithout
