Malfunction Indicator Light Inspection
NOTE:
CHECK engine light, located on instrument cluster, is referred to as Malfunction Indicator Light (MIL). Inspect MIL to ensure it is operational and will come on if a Diagnostic Trouble Code (DTC) is set.
- Turn ignition on with engine off. Malfunction Indicator Light (MIL) should come on and remain on. If MIL comes on, go to next step. If MIL does not come on, check bulb circuit on instrument cluster and wiring circuit between MIL and ECM. See WIRING DIAGRAMS article. See ENGINE CONTROL MODULE LOCATION .
- Start engine and ensure MIL goes off. If MIL goes off, no malfunction is detected at this time. If MIL remains on or blinks with engine running, a malfunction is detected. Proceed to RETRIEVING DIAGNOSTIC TROUBLE CODES .
