Malfunction Indicator Light Check

  1. Turn ignition on. If MIL illuminates, go to next step. If MIL does not illuminate, go to circuit test A1: MALFUNCTION INDICATOR LIGHT INOPERATIVE  under SYSTEM TESTS. If problem is found, repair as necessary. After repair, verify MIL operation.
  2. Start engine. If MIL turns off, system is okay. If driveability problems are present, go to TROUBLE SHOOTING - NO-CODES article. If MIL remains illuminated, check for DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES . If no DTC is stored in ECM memory and MIL is illuminated, go to circuit test A2: MALFUNCTION INDICATOR LIGHT REMAINS ON  under SYSTEM TESTS. If problem is found, repair as necessary. After repair, verify MIL operation.
