Checking The Wiring And Connectors

If the fault is intermittent, the wiring and connectors should be checked in the door(s) where the customer has complained of faulty function.

Check the wiring and the connectors between the lock units in the doors and each door control module. Look particularly for cables with damaged insulation that can result in intermittent short-circuits. Also check the connectors between the door control module and the lock unit. Check for oxidation.

If no faults are found in the wiring, replace the lock unit in the door being checked.

Remedy as necessary.
