Malfunction Indicator Lamp (MIL): Description

The MIL is located on the combination meter.

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

    If the MIL does not illuminate, check MIL circuit. Refer to "WIRING DIAGRAM ".

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

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