AUTO LIGHT SYSTEM

AUTO LIGHT SYSTEMPFP:28491
Component Parts and Harness Connector LocationBKS001O5
System DescriptionBKS001O6

BCM (Body Control Module) controls auto light operation according to signals from optical sensor, lighting
switch and ignition switch.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, tail, front
fog lamps and headlamps according to CAN communication signals from BCM.

Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to
voltage, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor inside it that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps.
For the details of the setting, Refer to LT- 1 9 , "
WORK SUPPORT" .
Optical sensor, power is supplied

from BCM terminal 17

to optical sensor terminal 1.
Optical sensor, ground is supplied

to optical sensor terminal 3

from BCM terminal 18.
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from optical sensor terminal 2
