Diagnostic Aids

WARNING: This page is about a different car, the 2002 Isuzu Trooper, 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.

To diagnose an intermittent fault, check for following conditions:

Poor connection at PCM. Inspect connections for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connection.
Inspect wiring harness for damage. If wiring harness appears to be okay, observe A/C clutch while moving connectors and wiring harnesses related to the A/C. A sudden clutch malfunction will indicate source of intermittent fault.
