to optical sensor terminal 1.
Optical sensor, ground is supplied
to optical sensor terminal 3
through 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
to BCM terminal 14.
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 11 6 , "
System
Description" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (or if auto light system is activated), and
the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM activates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turning the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minutes timer and a 45 seconds timer
When opening any door (door switch is ON), the 5 minutes timer starts and then headlamps go out five
minutes later
When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then head-
lamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 seconds timer is in
operation, the 5 minutes timer starts again
The timer stops when turning on the ignition switch or turning off the auto light switch under the above
conditions.
Delay timer control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003Q0
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 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 the high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003Q1
Refer to LAN-34, "CAN Communication Unit" .
Major Components and FunctionsNKS003Q2
Components Functions
BCM
Turns on/off circuits of tail light and headlamp according to signals from optical sensor, lighting switch
(AUTO), driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor
Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 50 to 1,300 lux)
