Diagnostic Aids

WARNING: This page is about a different car, the 2002 Isuzu Rodeo Sport, 2002 Isuzu Rodeo, 2002 Isuzu Axiom, and 2002 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.

Check for poor connection, rubbed-through wire insulation or a broken wire inside insulation. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection, and damaged harness. If harness appears to be okay, use DVOM to observe suspect driver circuits at PCM while moving connectors and harnesses. See WIRING DIAGRAMS article. A change in display will indicate location of fault. Check for poor, loose or corroded terminals or harness connectors in instrument cluster harness.
