Automatically turns on/off the parking lamps and the headlamps in accordance with ambient light.
Timing for when the lamps turn on/off can be selected using four modes.
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 lamps and the head-
lamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the set-
ting, refer to

When ignition switch is turn to “ON” position, and
When outside brightness is darker than prescribed level, input is supplied
●
to BCM (body control module) terminal 14
●
from optical sensor terminal 2.
The headlamps will then illuminate. For a description of headlamp operation, refer to
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 AUTO position, and the ignition switch is turned from
ON or ACC to OFF, and one of the front door is opened, the battery saver control feature is activated.
Under this condition, the headlamp remain illuminated for 5mimutes, then the headlamp are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
DELAY TIMER FUNCTION
When ignition switch ON and ACC are OFF while auto light switch is ON, BCM turns on/off headlamp. In delay
timer function, auto light sensor power source is OFF and BCM is not turned on/off by auto light sensor signal.
●
When the states ignition switch ON or ACC is ON and output judgment by auto light function is headlamp
ON turn to ignition switch ON or ACC are OFF and door switch (driver side), door switch (passenger side),
rear door switch (right side), rear door switch (lift side) and back door switch is ON, output judgment by
auto light function should be headlamp ON for 5 minutes by timer. After time out, output judgment by auto
light function should be headlamp OFF.
●
When the state is door switch (driver side), door switch (passenger side), rear door switch (right side), rear
door switch (lift side) and back door switches turned to ON from OFF 45 seconds or 5 minutes while timer
is counting, timer stops, and re
−
start counting for 5 minutes, then auto light function judges output as
headlamp ON. After time out, auto light function judges output as headlamp OFF.
●
When the states door witch (driver side), door switch (passenger side), rear door switch (right side), rear
door switch (lift side) and back door switch are ON turns to door switch (driver side), front door switch
(passenger side), rear door switch (right side), rear door switch (lift side) and back door switch are OFF 45
seconds or 5 minute timer while is counting, Timer stops, and re
−
start counting for 45 seconds, then auto
light function judges output as head lamp ON. After timer out and auto light function judges output as head
lamp OFF.
●
When the state is ignition switch ON or ACC is ON or auto light switch OFF while timer is counting, timer
stops counting and BCM turns on/off lamps according to headlamp function, front fog lamp function, auto
light function and headlamp battery save function.
Delay timer control mode can be changed by the function setting of CONSULT-II.
CAN Communication System Description
AKS004JJ
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.
