Auto Light Function (With Twilight Lighting Function)

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

Description

BCM detects the combination switch condition with the combination switch reading function.
BCM supplies voltage to the optical sensor when the power switch is turned ON or ACC.
Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
BCM filters outside brightness based on the optical sensor signal and judges outside brightness.
BCM detects change status of outside brightness according to outside brightness from the optical sensor signal and filtered outside brightness. Based on the change status, BCM judges ON/OFF condition of the exterior lamp.
BCM transmits each request signal to IPDM E/R and combination meter via CAN communication, according to ON/OFF condition by the auto light function.
NOTE: As to ON/OFF timing, the sensitivity depends on settings. The settings can be changed with CONSULT. Refer to "HEADLAMP : CONSULT FUNCTION (BCM - HEAD LAMP) ".
