MIL Operation

The Malfunction Indicator Light (MIL) is located on the instrument panel.

MIL Function

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

MIL Illumination

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