Auto Light Operation

WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

The auto light system operates the low beam and high beam headlamps, parking lamps, tail lamps and license plate lamps. The BCM monitors the combination switch (lighting and turn signal switch) position as a part of the BCM combination switch reading function. When the combination switch (lighting and turn signal switch) is in the AUTO position, the BCM automatically turns the lamps ON/OFF according to ambient light brightness.

NOTE: Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT. Refer to "BATTERY SAVER: CONSULT FUNCTION (BCM - BATTERY SAVER) ".
