SERVICE INFORMATION
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.

ILLUMINATION
System DescriptionINFOID:0000000001328422
Control of illumination lamps operation is dependent upon position of lighting switch (combination switch).
When lighting switch is placed in the 1ST or 2ND positi on (or if auto light system is activated), BCM (body con-
trol module) receives input signal requesting illuminati on lamps to illuminate. This input signal is communi-
cated to IPDM E/R (intelligent power distribution module engine room) through the CAN communication. The
CPU (central processing unit) located in the IPDM E/R co ntrols tail lamp relay coil. This relay, when energized,
directs power to illumination lamps, which then illuminate.
Power is supplied at all times
 through 10A fuse (No. 71, located in IPDM E/R)
 to tail lamp relay, located in IPDM E/R, and
 to CPU located in IPDM E/R.
Power is also supplied at all times
 through 50A fusible link (letter M, located in fuse, fusible link and relay box)
 to BCM terminal 55,
 through 15A fuse [No. 22 located in fuse block (J/B)]
 to BCM terminal 42,
 through 15A fuse (No. 78, located in IPDM E/R)
 to CPU located in IPDM E/R,
 through 10A fuse [No. 19 located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 21 and
 to combination meter terminal 8.
With ignition switch in ON or START position, power is supplied
 to ignition relay, located in IPDM E/R, from battery direct,
 through 15A fuse [No. 1 located in fuse block (J/B)]
 to BCM terminal 38,
 through 10A fuse [No. 12, located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 22 and
 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 combination meter terminal 4 and
 to BCM terminal 11.
Ground is supplied
 to BCM terminals 49 and 52
 to unified meter and A/C amp. terminals 29 and 30, and
 to combination meter terminals 5, 6, and 15
 through grounds M35, M45, and M85,
 to IPDM E/R terminals 38 and 60
 through grounds E21, E50, and E51.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal
requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R through the CAN
communication. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized, directs
power
 through IPDM E/R terminal 22
 to glove box lamp terminal 1
 to A/T device (illumination) terminal 11
 to snow mode switch (illumination) terminal 5
 to VDC off switch (illumination) terminal 3
 to clock (illumination) terminal 3

With power and ground supplied, illumination lamps illuminate.
EXTERIOR LAMP BATTERY SAVER CONTROL
When the lighting switch is in the 1ST or 2ND position (or if auto light system is activated), and ignition switch
is turned from ON or ACC to OFF, batte ry saver control function is activated.
Under this condition, illumination lamps remain illuminated for 5 minutes, then illumination lamps are turned
off.
When the lighting switch is turned from OFF to 1ST or 2 ND position (or if auto light system is activated) after
illumination lamps are turned off by battery save r control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
CAN Communication System DescriptionINFOID:0000000001328423
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 s peed 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 CA N 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.
