MIL Operation

The MIL is located on the instrument panel.

MIL Function

• The MIL informs the driver that a malfunction has occurred and the vehicle should be taken in for service as soon as possible.
• The MIL illuminates during a bulb test and a system test.
• A Diagnostic Trouble Code (DTC) will be stored if a MIL is requested by the PCM.

MIL Illumination

• The MIL will illuminate with ignition switch on and the engine not running.
• The MIL will turn off when the engine is started.
• The MIL will remain ON if the self-diagnostic system has detected a malfunction.
• The MIL may turn OFF if the malfunction is not present.
• If the MIL is illuminated and then the engine stalls, the MIL will remain illuminated so long as the ignition switch is ON.
• If the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition switch is cycled OFF, then ON.
