Malfunction Indicator Lamp (MIL): Description

The MIL is located on the instrument panel.

  1. The MIL will light up when the ignition switch is turned ON without the engine running. This is a bulb check.

    If the MIL does not light up, refer to WARNING LAMPS , or see MIL AND DATA LINK CONNECTOR .

  2. When the engine is started, the MIL should go off.

    If the MIL remains on, the on board diagnostic system has detected an engine system malfunction.
