4. FAULT FINDING PROCEDURE (continued)
4.1 Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily clear 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
When handling the wiring, use the diagnostic tool to detect any change in the status of the faults from "stored" to
"present".
Make sure that the connectors are firmly secured.
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.
Checking earth insulation
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5 V. The correct measured value is 0 V.
Checking insulation against + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value should be 0 V
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result must be between: 0 Ω < X < 2 Ω for every connection. The line must
be fully checked, and the intermediate connections are only included in the method if this saves time during the fault
finding procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured
value must be between: 0 Ω < X < 2 Ω.
Checking the supply
This check may be carried out using a test light (21 W or 5 W depending on the maximum authorised load)

1. Visual inspection of the connection:
–Check that the connector is connected correctly and that the male and female parts of the connection are correctly
coupled.
2. Visual inspection of the area around the connection:
–Check the condition of the mounting (pin, strap, adhesive tape, etc.) if the connectors are attached to the vehicle.
–Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
–Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating material
(wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
3. Visual inspection of the plastic casing:
–Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, openings, etc.).
–Check that there is no heat damage (casing melted, darker, deformed, etc.).
–Check that there are no stains (grease, mud, liquid, etc.).
4. Visual inspection of the metal contacts:
(The female contact is called CLIP. The male contact is called TAB).
–Check that there are no bent contacts (the contact is not inserted correctly and can come out of the back of the
connector). The contact comes out of the connector when the wire is gently pulled.
–Check that there is no damage (folded tabs, clips open too wide, blackened or melted contact, etc.).
–Check that there is no oxidation on the metal contacts.
5. Visual inspection of the sealing:
(Only for watertight connectors)
–Check for the seal on the connection (between the 2 parts of the connection).
–For unit joints (1 for each wire), check that the unit joints are present on each electrical wire and that they are
correctly positioned in the opening (level with the housing). Check that plugs are present on openings which
are not used.
–For a grommet seal (one seal which covers the entire internal surface of the connector), check that the seal
is present.
–For gel seals, check for gel in all of the openings without removing the excess or any protruding sections
(it does not matter if there is gel on the contacts).
–For hotmelt sealing (heat-shrink sheath with glue), check that the sheath has contracted correctly on the rear
of the connectors and electrical wires, and that the hardened glue comes out of the side of the wire.
–Check that there is no damage to any of the seals (cuts, burns, significant deformation, etc.).
If a fault is detected, consult Technical Note 6015A, Repairing electrical wiring.
