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 Diagnosis Description .
