Maintenance Indicator Light (Mil) Check

  1. Turn ignition on. If MIL illuminates, go to next step. If MIL does not illuminate, go to CIRCUIT TEST A-1 for appropriate application. Repair as necessary.
  2. Start engine. If MIL goes out, system is okay. If driveability problems are present, see TESTS W/O CODES article. If MIL remains on, check for DTCs. See RETRIEVING DTCS  . If no DTC is stored in PCM memory with MIL illuminated, go to CIRCUIT TEST A-2 for appropriate application. Repair as necessary.
