Diagnosis Procedure

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

  1. CHECK PARKING LAMP FUSES
    1. Turn the ignition switch OFF.
    2. Check that the following fuses are not open.
