Auto Light Function (With Twilight Lighting Function) - Description

BCM detects the combination switch condition with the combination switch reading function.
BCM receives the vehicle speed signal from combination meter via CAN communication and detects the vehicle speed and the driving distance.
BCM supplies voltage to the optical sensor when the ignition switch is turned ON.
Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
When ignition switch is turned ON, BCM detects outside brightness from the optical sensor signal and judges ON/OFF condition of each exterior lamp, depending on the outside brightness condition (standard or twilight).
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 using CONSULT. Refer to CONSULT FUNCTION (BCM - HEAD LAMP) .
