PRECAUTIONS

PRECAUTIONS PFP:00011

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS0040O

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:
q 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.
q 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.
q 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 harness connec-
tors.
General precautions for service operations EKS0040P

q Never work with wet hands.
q The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect battery negative cable (negative ter-
minal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
q Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
q When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
q When checking the headlamp on/off operation, check it on vehi- PKIA0183E
cle and with the power connected to the vehicle-side connector.
q 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.
q 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.
q When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
q 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. EL-3422D

q When adjusting the headlamp aiming, turn the aiming adjust-
ment screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the
screw, and then turn it in the tightening direction.)
q Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
Wiring Diagrams and Trouble Diagnosis EKS0040Q

When you read wiring diagrams, refer to the following:
q GI-12, "How to Read Wiring Diagrams"
q PG-3, "POWER SUPPLY ROUTING CIRCUIT"
When you perform trouble diagnosis, refer to the following:
q GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"
q GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident"

System Description EKS0040S

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM receives input requesting the head- L
lamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent power distribution
module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R con-
trols the headlamp high and headlamp low relay coils. When energized, these relays direct power to the
M
respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
q to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and
q to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and
q to BCM (body control module) terminal 7
q through 50A fusible link [letter f , located in the fuse and fusible link box].
With the ignition switch in the ON or START position, power is supplied
q to BCM (body control module) terminal 35
q through 10A fuse [No. 12, located in the fuse block (J/B)].
With the ignition switch in the ACC or ON position, power is supplied
q to BCM (body control module) terminal 36
q through 10A fuse [No. 6, located in the fuse block (J/B)].
Ground is supplied

LT-5
HEADLAMP (FOR USA)

q to BCM (body control module) terminals 8, 27, and 63
q through body grounds M57, M61, E15, and E24.
Low Beam Operation
With the lighting switch in 2ND position, the BCM (body control module) receives input requesting the head-
lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine
room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the head-
lamp low relay coil. When energized, this relay directs power
q to 15A fuse [No. 50, located in the IPDM E/R]
q through terminal 27 of the IPDM E/R
q to terminal 1 of headlamp RH, and
q to 15A fuse [No. 49, located in the IPDM E/R]
q through terminal 21 of the IPDM E/R
q to terminal 1 of headlamp LH.
Ground is supplied at all times
q to terminal 2 of headlamp RH
q through body grounds E15 and E24, and
q to terminal 2 of headlamp LH
q through body grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM (body control module)
receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R
(intelligent power distribution module engine room) across the CAN communication lines. The central process-
ing unit of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power
q to 10A fuse [No. 47, located in the IPDM]
q through terminal 24 of the IPDM
q to terminal 1 of headlamp RH, and
q to 10A fuse [No. 48, located in the IPDM]
q through terminal 22 of the IPDM
q to terminal 1 of headlamp LH.
Ground is supplied
q to terminal 2 of headlamp RH
q through body grounds E15 and E24, and
q to terminal 2 of headlamp LH
q through body grounds E15 and E24.
With power and ground supplied, the high beam headlamps and the HIGH BEAM indicator illuminate.
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 feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
Refer to LT-46, "System Description" for auto light operation.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-87, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP (IF EQUIPPED)
The low beam headlamps may be equipped with xenon type bulbs. Xenon bulbs do not use a filament.
Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a
LT-6
HEADLAMP (FOR USA)

mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color. A
Following are some of the advantages of the xenon type headlamp.
q The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
q Light output is nearly double that of halogen headlamps, affording increased area of illumination. B
q The light features a high relative spectral distribution at wavelengths to which the human eye is most sen-
sitive. This means that even in the rain, more light is reflected back from the road surface toward the vehi-
cle, for added visibility. C
q Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System Description EKS0040T
D
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 E
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.
