AUTO LIGHT OPERATION
For auto light operation, refer to LT- 5 4 , "System Description" in “AUTO LIGHT SYSTEM”.
CAN Communication System DescriptionAKS007N1
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.

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 LT- 5 4 , "
System Descrip-
tion" .
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 turn on/off headlamp. In delay
timer function, auto timer sensor power source is OFF and BCM is not turned on/off by auto 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 front door switch (driver side), front door switch (pas-
senger side) is ON, output judgment by auto light function should be headlamp ON for 5 minutes by tamer.
After time out, output judgment by auto light function should be headlamp OFF.

When the state is front door switch (driver side), front door switch (passenger side), rear door switch LH,
rear door switch RH or back door switch is turner 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 head-
lamp ON. After time out, auto light function judges output as headlamp OFF.

When the states front door witch (driver side), front door switch (passenger side), rear door switch LH,
rear door switch RH or back door switch is ON turns to front door witch (driver side), front door switch
(passenger side), rear door switch LH, rear door switch RH or back door switch are OFF 45seconds or
5minute 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, 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 (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
