Self-Diagnostic Procedure (Without Consult): Description
WARNING: This page is about a different car, the 2013 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.
If the engine starts when there is something wrong with the 4WD system, the 4WD warning lamp turns ON or flickers in the combination meter. When the system functions properly, the warning lamp turns ON when the ignition switch is turned to "ON", and it turns OFF after engine starts. To locate the cause of a problem, start the self-diagnosis function. The 4WD warning lamp in the combination meter will indicate the problem area by flickering according to the self-diagnostic results. Refer to "DTC INDEX ".
