AUTO LIGHT ADJUSTMENT SYSTEM

Description
- 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 judges dimming/brightening of combination meter and display according to brightness outside the vehicle, when power switch is ON.
- BCM transmits dimmer signal to combination meter via CAN communication, according to auto light adjustment conditions. Dimmer signal is also transmitted to AV control unit.
NOTE:
As to dimming/brightening timing, the sensitivity depends on settings. The settings can be changed with CONSULT. Refer to "HEADLAMP : CONSULT Function (BCM HEAD LAMP)" Head Lamp.
