System Description
EKS00FV0
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 uses an optical sensor 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
LT-45, "SETTING CHANGE FUNCTIONS"
.
Optical sensor ground is supplied
●
to optical sensor terminal 3
●
through BCM (body control module) terminal 18.
When ignition switch is turned to "ON" position and when outside brightness is darker than prescribed level,
input is supplied
●
to BCM terminal 58
●
from optical sensor terminal 4.
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 doors is opened, the battery saver control feature 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
When the ignition switch is ON and auto light switch is ON, the BCM turns on/off the headlamps. In delay timer
function, ignition is OFF, auto light sensor power source is OFF and the headlamps are not turned on/off by the
BCM. On condition that:
●
when the state of ignition switch ON or ACC is ON and output judgment by auto light function is headlamp
ON changes to ignition switch and ACC are OFF and any door switch is ON, output judgment by BCM
should be headlamp ON for 5 minutes by timer. After time out, output judgment by BCM should be head-
lamp OFF.
●
when the state of any door switch is turned to ON from OFF while 45 second or 5 minute timer is counting,
timer stops, and restarts counting for 5 minutes, then BCM judges output as headlamp ON. After time out,
BCM judges output as headlamp OFF.
●
when the state of front door switch LH, front door switch RH, rear door switch LH, rear door switch RH or
back door latch (door ajar switch) is ON turns to all door switches are OFF while 45 second or 5 minute
timer is counting, timer stops, and restarts counting for 45 seconds, then BCM judges output as headlamp
ON. After timer out, BCM judges output as headlamp 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 or with the display (with
NAVI).

Components
Functions
BCM
●
Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch
(AUTO), front door switch LH, front door switch RH, rear door switches, back door switch, and igni-
tion switch (ON, OFF).
Optical sensor
●
Converts ambient light (lux) to voltage, and sends it to BCM. (Detects lightness of 50 to 1,300 lux)
