AUTO LIGHT ADJUSTMENT SYSTEM : System Description
INFOID:0000000009653472
SYSTEM DIAGRAM
OUTLINE
Auto light adjustment system is controlled by each function 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 (Except for CANADA). 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. Refer to
EXL-32, "HEADLAMP : CONSULT Function (BCM - HEADLAMP) (Xenon Type Headlamp)"
.
