Auto Light Function

WARNING: This page is about a different car, the 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

BCM detects the combination switch condition with the combination switch reading function.
BCM supplies voltage to optical sensor when the ignition switch is turned ON or ACC.
Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
BCM judges outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior lamp and each illumination according to the outside brightness.
BCM transmits each request signal to IPDM E/R with CAN communication according to ON/OFF condition by the auto light function.

NOTE: ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT-III. Refer to "HEADLAMP : CONSULT-III FUNCTION (BCM - HEAD LAMP) ".
