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.

 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

XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps . Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.
 The light produced by the headlamps is white color si milar to sunlight that is easy to the eyes.
 Light output is nearly double that of halogen headl amps, affording increased area of illumination.
 Counter-reflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.
 Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionINFOID:0000000001328267
CAN (Controller Area Network) is a serial communication li ne 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.

General Information for Xenon Headlamp Trouble DiagnosisINFOID:0000000001328284
In most cases, malfunction of xenon headlamp - “does not ill uminate”, “flickers” or “dark” - is caused by a mal-
functioning xenon bulb. A malfunctioning HID control unit or lamp housing, however, may be a cause. Be sure
to perform trouble diagnosis following the steps described below.
Caution:INFOID:0000000001328285
 Installation or removal of connector must be done with lighting switch OFF.
 Disconnect the battery cable from the negative terminal or remove power fuse.
 When the lamp is illuminated (when lighting switch is ON), never touch harness, HID control unit, inside of
lamp, or lamp metal parts.
 To check illumination, temporarily install lamp in vehicle. Be sure to connect power at vehicle side connector.
 If error can be traced directly to electrical system, fi rst check for items such as blown fuses and fusible links,
broken wires or loose connectors, dislocated terminals, and improper connections.
 Never work with wet hands.
 Using a tester for HID control unit circuit trouble diagnosis is prohibited.
 Disassembling HID control unit or harnesses ( bulb socket harness, ECM harness) is prohibited.
 Immediately after illumination, light intensity and color will fluctuate, but there is nothing wrong.
 When bulb has come to end of its life, brightness will dr op significantly, it will flash repeatedly, or light color
will turn reddish. 30 – 6 : Continuity should exist.
