AUTO LIGHT SYSTEM
Revision: 2005 July 2005 FX
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from BCM terminal 14

to optical sensor terminal 2
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 5 5 , "
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 5 mimutes, 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
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-minute timer and a 45-second timer

When opening any door (door switch is ON), the 5-minute 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 forty-five seconds later. If any door is opened (door switch ON) while the 45-second timer is
in operation, the 5-minute 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 or display.
CAN Communication System DescriptionAKS007ET
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 UnitAKS0080U
Refer to LAN-30, "CAN Communication Unit" .
Major Components and FunctionsAKS007EV
Components Functions
BCM

Turns on/off circuits of tail light and headlamp according to signals from light 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)

Revision: 2005 July 2005 FX

to BCM terminal 38.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51.
FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power

through IPDM E/R terminal 37

to front fog lamp LH terminal 1,

through IPDM E/R terminal 36

to front fog lamp RH terminal 1.
Ground is supplied

to front fog lamp LH terminal 2

through grounds E21, E50 and E51,

to front fog lamp RH terminal 2

through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.
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 (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
