Diagnostic Aids

Check ECU-IG fuse, STOP fuse and ECU-B fuse.

An intermittent condition may be caused by rubbed-through insulation, or a wire broken inside insulation. Check harness connectors for backed-out or damaged terminals, improper mating or broken connector lock, before replacing component.
