PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612924
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
General Precaution for Service OperationINFOID:0000000001328264
 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 connecting 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 vehicle
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 headl amp bulb just after the headlamp is turned off, because
it is very hot.
 Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connecto r, 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 perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
 When adjusting the headlamp aiming, turn the aiming adjus tment 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.)
 Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

Component Parts and Har ness Connector LocationINFOID:0000000001328265
System DescriptionINFOID:0000000001328266
Control of the headlamp system operation is dependent upon t he position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) through the CAN communication lines. The CPU (central
processing unit) located in the IPDM E/R contro ls the headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
OUTLINE

 to ignition relay, located in IPDM E/R, from battery direct,
 through 10A fuse (No. 71, located in IPDM E/R)

 to combination meter terminal 7.
With ignition switch in 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 terminals 49 and 52
 through grounds M35, M45 and M85,

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IP DM E/R through the CAN communication lines. The CPU
located in the IPDM E/R controls the headlamp lo w relay coil, which when energized, directs power
 through 15A fuse (No. 76, located in IPDM E/R)
 through IPDM E/R terminal 20
 to front combination lamp RH terminal 6,
 through 15A fuse (No. 86, located in IPDM E/R)
 through IPDM E/R terminal 30
 to front combination lamp LH terminal 6.
Ground is supplied
 to front combination lamp RH and LH terminals 7
 through grounds E21, E50 and E51,
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the HIGH or PASS position, the BCM receives input
signal requesting the headlamp high beams to illuminate. Th is input signal is communicated to the IPDM E/R
through the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil and low relay coil, which when energized, directs power
 through 15A fuse (No. 76, located in IPDM E/R)
 through IPDM E/R terminal 20
 to front combination lamp RH terminal 6,
 through 15A fuse (No. 86, located in IPDM E/R)
 through IPDM E/R terminal 30
 to front combination lamp LH terminal 6,
 through 10A fuse (No. 72, located in IPDM E/R)
 through IPDM E/R terminal 27
 to front combination lamp RH terminal 5,
 through 10A fuse (No. 74, located in IPDM E/R)
 through IPDM E/R terminal 28
 to front combination lamp LH terminal 5.
Ground is supplied
 to front combination lamp RH and LH terminals 7
 through grounds E21, E50 and E51,
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
The unified meter and A/C amp. that received the hi gh beam request signal by BCM through the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
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 illumi nated for 5 minutes, then the headlamps are turned OFF.
