Diagnostic Aids
    • Inspect wiring harness for damage. Check for broken or chaffed insulation.
    • If fault is suspected to be intermittent, wiggling harness wiring may help in locating fault.
    • Check for poor connections at the BCM. Inspect harness connectors for backed out terminals, improper terminal mating, broken connector locks, improperly formed or damaged terminals and poor terminal-to-wire connection (terminal crimped over wire insulation and not conductors).
