System Description

NKS001OS

BCM (Body Control Module) controls auto light operation according to signals from optical sensor, lighting
switch, driver door switch, passenger door switch and ignition switch.

Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to
voltage, then sends the optical sensor signal to BCM.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, tail lamps
and headlamps low according to CAN communication signals from BCM.

For a description of headlamp low operation, refer to 

LT-6, "System Description"

 .

For a description of parking, license plate, side marker and tail lamps operation, refer to

AUTO LIGHT SYSTEM

Revision: 2006 August

2006 Murano

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-89, "SETTING CHANGE FUNCTIONS"

 .

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. 

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-81, "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 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 Description

NKS001OT

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.
