AUTO LIGHT SYSTEM
Revision: 2007 April2007 M35/M45
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 (or if auto light system is activated), and
the ignition switch is turned from ON or ACC to OFF, the battery saver control function 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
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 minutes timer and a 45 seconds timer

When opening any door (door switch is ON), the 5 minutes 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 45 seconds later. If any door is opened (door switch ON) while the 45 seconds timer is in
operation, the 5 minutes 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.
CAN Communication System DescriptionNKS003Q0
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 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 the high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.

Major Components and FunctionsNKS003Q2
Components Functions
BCM

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

HEADLAMP AUTO AIMING OPERATION
The height sensor detects a change in height of rear vehicle with ignition switch ON, and transmits signals to
the AFS control unit:
When ignition switch is turn to ON position, power is supplied

to height sensor terminal 1

through AFS control unit terminal 6.
When ignition switch is turned to ON position, height sensor input signal is supplied

to AFS control unit terminal 28

through height sensor terminal 2.
Ground is supplied

to height sensor terminal 3

through AFS control unit terminal 8.
Aiming motor driving signal (voltage signal that corresponds to the vehicle height) is transmitted depending on
the height sensor signal at the start of the engine

to front combination lamp LH terminal 12

through AFS control unit terminal 40,

to front combination lamp RH terminal 12

through AFS control unit terminal 19.
Output of aiming motor driving signal is maintained unless headlamp (HIGH/LOW) illuminate detected.
Auto aiming control operation starts when headlamps (HIGH/LOW) illuminate detected.
When headlamps (HIGH/LOW) illuminate, output of aiming motor driving signal is changed according to the
height sensor signal. After the change, it is changed according to height sensor signals with predetermined
timing based on driving condition while headlamps are ON.
Auto Aiming Operation
AFS control unit starts outputting aiming motor drive signal when the engine starts, and continues to output it
until the engine stops. Aiming motor drive signal changes output when the specified conditions described
below are met.
Headlamp aiming motors set the low beam projectors according to aiming motor drive signals received from
AFS control unit, both headlamp aiming motors cause the low beam projectors to move to the position com-
manded by the signal.
The aiming motor drive signal level retains when the following conditions are not met.

AFS control unit operation when the vehicle is stopped (low beam headlamps illuminated)
Headlamp aiming motor drive signal is changed when vehicle height is stabilized with a parked condition,
depending on the height sensor signal detected with height sensor signal by AFS control unit.

AFS control unit operation when the vehicle is running (low beam headlamps illuminated)
When vehicle is running, headlamp aiming motor drive signal is changed depending on the height sensor
signal which is detected when AFS control unit detects constant steady speed of vehicle.
When the vehicle is accelerating or decelerating, AFS control unit keeps headlamp aiming motor drive sig-
nal voltage level rather than changing it, so that the low beam projectors of both headlamps do not oper-
ate.

FRONT FOG LAMP
Revision: 2007 April2007 M35/M45
FOG LAMP OPERATION
The fog lamp switch is built in combination switch. The lighting switch must be in 2ND position or AUTO posi-
tion (headlamp is ON) and fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU located in IPDM E/R grounds coil side of the fog lamp
relay. Fog lamp relay then directs power

through IPDM E/R terminal 37

to front fog lamp RH terminal 1,

through IPDM E/R terminal 36

to front fog lamp LH terminal 1.
Ground is supplied

to front fog lamp RH terminal 2

through grounds E22 and E43,

to front fog lamp LH terminal 2

through grounds E22 and E43.
With power and grounds supplied, the front fog lamps illuminate.
The unified meter and A/C amp. that received the front fog lamp request signal by BCM across the CAN com-
munication makes a front fog lamp indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function 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.

NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
