Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring 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.

Faults that activate the OBD warning light
PRECAUTIONS/RISKS
The main recommendation regarding the system is:
Never electrically disconnect the injectors with the engine running.
The piezoelectric technology used for the injector system means that the injectors receive a control pulse to open
and another control pulse to close. If the injector is disconnected between these 2 pulses while the engine is
running, i.e. during the actual injection process, the injector will remain open long enough to create very
unfavourable thermodynamic conditions in the cylinder(s) or generate hydraulic pressure which may result in
engine damage. Tool fault Associated DTC Diagnostic tool title
