DAYTIME LIGHT SYSTEM
Revision: 2006 July 2007 FX35/FX45
DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationNKS002VW
System DescriptionNKS002VX
Daytime light system turns ON daytime light lamps while driving. Daytime light lamps are not turned ON if
engine is activated with parking brake ON. Release parking brake to turn ON daytime light lamps. The lamps
turn OFF when the lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when the
lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake
itself).
The parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN com-
munication line, and control daytime light system.

AUTO LIGHT SYSTEMPFP:28491
Component Parts and Harness Connector LocationNKS002WB
System DescriptionNKS002WC
Automatically turns ON/OFF 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 LT- 6 4 , "
SETTING CHANGE FUNCTIONS" .
Optical sensor control mode can be changed by the function setting of CONSULT-II or display.
Optical sensor, power is supplied

from BCM (body control module) terminal 17

to optical sensor terminal 1.
Optical sensor, ground is supplied

to optical sensor terminal 3

through BCM terminal 18.

AUTO LIGHT SYSTEM
Revision: 2006 July 2007 FX35/FX45
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from optical sensor terminal 2

to BCM terminal 14
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" .
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 5 min-
utes later

When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then head-
lamps go out 45 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 DescriptionNKS002WD
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 UnitNKS002WE
Refer to LAN-49, "CAN System Specification Chart" .
Major Components and FunctionsNKS002WF
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 800 to 2,500 lux)
