Malfunction Indicator Light Inspection

NOTE: Malfunction Indicator Light (MIL) may also be referred to as CHECK ENGINE light. Inspect MIL to ensure it is operational and will come on if a Diagnostic Trouble Code (DTC) is set.
  1. Turn ignition on. Check that MIL comes on and remains on. MIL is displayed as an engine icon located just below the tachometer on instrument cluster on instrument panel. If MIL comes on and remains on, go to next step. If MIL does not come on, check bulb circuit on instrument cluster and Violet wire and electrical connectors between MIL and Engine Control Module (ECM). See WIRING DIAGRAMS article. ECM is located behind glove box. See Figure.
  2. 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 TESTING PROCEDURE .
