AUTO LIGHT OPERATION
Applicable lamps

Low beam headlamp

Parking, license plate and tail lamps

High beam headlamp (with the lighting switch in HIGH BEAM position)

Front fog lamp (with the lighting switch in front fog lamp ON position)
When the lighting switch is in AUTO position with the ignition switch in ON position, BCM detects the AUTO
LIGHT (ON) by BCM combination switch reading function. BCM turns automatically ON/OFF the applicable
lamps according to ambient brightness depending on the following condition.

It turns ON applicable lamps in 3 seconds when ambient brightness is less than 1250 lux.

This lighted lamps is turned OFF in 5 seconds when ambient brightness becomes 2500 lux or higher.
Releasing Function:

Turn ignition switch to the OFF position, or

Change lighting switch to the OFF, 1ST, 2ND position.
NOTE:
Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-II. Refer to LT- 1 9 ,
"WORK SUPPORT" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .

Refer to LT- 1 9 6 , "System Description" .
CAN Communication System DescriptionBKS001O7
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBKS001O8
Refer to LAN-49, "CAN System Specification Chart" .
Major Components and FunctionsBKS001O9
Components Functions
BCM

Turns ON/OFF circuits of parking lamp, license plate lamp, tail lamp and headlamp according to signals from
optical sensor, lighting switch (AUTO), and ignition switch (ON, OFF).
Optical sensor

Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2500 lux)
