MIL Operation

The MIL is located on the Instrument Panel Cluster (IPC).

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

• The MIL will illuminate with the ignition 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.
