Diagnostic Aids

Inspect for the following conditions:

• If the engine runs okay, inspect for a malfunctioning MIL, an open in the MIL control circuit, or an open in the instrument cluster (IC) ignition feed.
• If the engine cranks but will not run, inspect for an open PCM ignition or battery feed or a faulty PCM to engine ground.
• PCM and engine grounds for clean and secure connections.
