Malfunction Indicator Lamp (MIL): Description

WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

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.
