4. FAULT FINDING PROCEDURE (CONTINUED)
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 of the connection
●Check that the connector is connected correctly and that the male and female parts of the connection are
correctly coupled.
Visual inspection of the area around the connection
●Check the condition of the mounting (pin, strap, adhesive tape, etc.), that 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.
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.).
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 spring contact of the connector when pulling the wire slightly.
●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. Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of poor
electrical contact. Limit the number of connections/disconnections as much as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be two types of connections:
–Connector / Connector
–Connector / Device
