OUTLINE
Auto light adjustment system is controlled by each f unction of BCM, combination meter and AV control unit
Control by BCM Auto light system
 Auto light adjustment system
AUTO LIGHT ADJUSTMENT SYSTEM
Description
 BCM supplies voltage to the 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 dimming/brightening of combination meter and display according to brightness outside the vehi- cle, when ignition switch is ON.
 BCM transmits dimmer signal to combination meter via CAN communication, according to auto light adjust- ment 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 CON-
SULT-III. Refer to EXL-23, "
HEADLAMP : CONSULT-III F unction (BCM - HEAD LAMP)".
Auto Light Adjustment Timing Table
When the ignition switch is ON, the illumination of co mbination meter and display switches dimming/brighten-
ing in the following condition.
BCM switches the illumination of combination me ter and display to dimming when outside brightening
obtained from the optical sensor signal is 1250 lx or le ss for 3 seconds or more. And BCM switches the illumi-
nation of combination meter and display to brightening when outside brightening from the optical sensor signal
is 2500 lx or more for 5 seconds or more.
