MIL Operation

Malfunction Indicator Light (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 diagnostic.

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 the malfunction is not present.
• If MIL is illuminated and then engine stalls, the MIL will remain illuminated so long as the ignition switch is ON.
• If MIL is not illuminated and engine stalls, the MIL will not illuminate until the ignition switch is cycled OFF, then ON.
