PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS002B7
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
General Precautions for Service OperationsBKS002B8

Never work with wet hands.

Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).

Turn the lighting switch OFF before disconnecting and connect-
ing the connector.

When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.

When checking the headlamp on/off operation, check it on vehi-
cle and with the power connected to the vehicle-side connector.

Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.

Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.

When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.

Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
on hand when replacing the bulb.

Do not use organic solvent (paint thinner or gasoline) to clean
lamps and to remove old sealant.

TURN SIGNAL AND HAZARD WARNING LAMPS

TURN SIGNAL AND HAZARD WARNING LAMPSPFP:26120
Component Parts and Harness Connector LocationBKS001PM
System DescriptionBKS001PN

BCM (Body Control Module) controls turn signal lamp (RH and LH) and hazard warning lamp operation.

Unified meter and A/C amp. operates turn (RH and LH) indicator according to CAN communication sig-
nals from BCM.
OUTLINE
Power is supplied at all times

through 50A fusible link (letter M, located in fuse and fusible link block)

to BCM terminal 55,

through 15A fuse [No. 17, located in fuse block (J/B)]

to BCM terminal 42 and

to combination meter terminal 7.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 8.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.

Ground is supplied

to BCM terminal 52 and

to combination meter terminals 10, 11 and 12

through grounds M71 and M72.
TURN SIGNAL OPERATION
Turn Signal Lamp RH
When the turn signal switch is in RH position with the ignition switch in ON position, BCM detects the TURN
RH (ON) by BCM combination switch reading function. BCM outputs the flasher output signal (right) to turn
signal lamp RH intermittently. And then, turn signal lamp RH start flashing operation. BCM sends turn indicator
signal (RH) through CAN communication. BCM supplies power

through BCM terminal 46

to front combination lamp RH terminal 8

to side turn signal lamp RH terminal 1 and

to rear combination lamp RH terminal 1.
Ground is supplied

to front combination lamp RH terminal 4 and

to side turn signal lamp RH terminal 2

through grounds E1 and E31,

to rear combination lamp RH terminal 2

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17 (without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (RH) through CAN communication, then makes
turn RH indicator start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the blinking of the turn signal lamp RH.
Turn Signal Lamp LH
When the turn signal switch is in LH position with the ignition switch in ON position, BCM detects the TURN LH
(ON) by BCM combination switch reading function. BCM outputs the flasher output signal (left) to turn signal
lamp LH intermittently. And then, turn signal lamp LH start flashing operation. BCM sends turn indicator signal
(LH) through CAN communication. BCM supplies power

through BCM terminal 45

to front combination lamp LH terminal 8

to side turn signal lamp LH terminal 1 and

to rear combination lamp LH terminal 1.
Ground is supplied

to front combination lamp LH terminal 4 and

to side turn signal lamp LH terminal 2

through grounds E1 and E31,

to rear combination lamp LH terminal 2

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17 (without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (LH) through CAN communication, then makes
turn LH indicator start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the blinking of the turn signal lamp LH.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, BCM detects the hazard switch signal ON. BCM outputs the flasher
output signal (right) and flasher output signal (left) to turn signal lamp (RH and LH) intermittently. And then turn
signal lamp (RH and LH) start flashing operation. And BCM sends turn indicator signal (RH and LH) through
CAN communication. Hazard switch supplies ground

to BCM terminal 29

through hazard switch terminal 2,

to hazard switch terminal 1

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17(without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (RH and LH) through CAN communication, then
makes turn (RH and LH) indicator start flashing operation interlocked with the buzzer sounds in combination
meter.
With power and ground supplied, BCM controls the blinking of the hazard warning lamp.
INTERLOCKED HAZARD LAMP OPERATION WITH REMOTE KEYLESS ENTRY SYSTEM
BCM receives the keyfob signal (door lock/unlock signal) from remote keyless entry receiver, then BCM con-
trols hazard lamps.
Refer to BL-46, "
REMOTE KEYLESS ENTRY SYSTEM" .
INTERLOCKED HAZARD LAMP OPERATION WITH INTELLIGENT KEY SYSTEM
BCM receives the door lock/unlock signal from Intelligent Key unit through CAN communication, then BCM
controls hazard lamps.
Refer to BL-68, "
INTELLIGENT KEY SYSTEM" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionBKS001PO
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.
