Malfunction Indicator Light Inspection
NOTE:
The Malfunction Indicator Light (MIL) on the instrument panel may also be referred to as CHECK ENGINE light. Inspect MIL to ensure it is operational and will come on if a trouble code is stored.
- Turn ignition on with engine off. MIL should come on and remain on. If MIL does not come on, check bulb circuit on instrument panel and wiring circuit between MIL and ECM. See Figure for ECM location. See wiring diagram in WIRING DIAGRAMS article.
- Start engine and ensure MIL goes off. If MIL remains on with engine running, a malfunction is detected. Proceed to RETRIEVING TROUBLE CODES under TESTING & REPAIR PROCEDURE.
