*1: Without daytime light system, *2: With daytime light system, *3: Double cab, *4: King cab
System DescriptionEKS00Q7W
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 system uses an light and rain sensor that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking lamps and the
headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the
setting, refer toLT-60, "
WORK SUPPORT".
Light and rain sensor, power is supplied
lfrom BCM terminal 42
lto light and rain sensor terminal 1.
Light and rain sensor, ground is supplied

When ignition switch is turned to ON position and when outside brightness is darker than prescribed level,
input is supplied
lto BCM terminal 24
lfrom light and rain sensor terminal 2.
The headlamps will then illuminate. For a description of headlamp operation, refer toLT-49, "
System Descrip-
tion".

Components Functions
BCM
lTurns ON/OFF circuits of tail light and headlamp according to signals from light and rain sensor, lighting switch
(AUTO), driver door switch, passenger door switch, rear door switches, back door switch, glass hatch opener
switch and ignition switch (ON, OFF).
Light and rain
sensor
lConverts outside brightness (lux) to voltage, and sends it to BCM. (Detects lightness of 50 to 1,300 lux.)
