SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003532849
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. 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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
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 har-
ness connectors.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000003532850
• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bags and seat belt
pre-tensioners to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
• The air diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front of
the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
• Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
• After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Occupant Classification System PrecautionINFOID:0000000003532851

FRONT PASSENGER AIR BAG MODULE
Removal and InstallationINFOID:0000000003532875
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of the service replacement passenger air bag module. Refer to
"WIRING HARNESS MODIFICATION" for wiring harness modification procedure.
REMOVAL
CAUTION:
• Do not attempt to repair or replace damaged direct-connect front passenger air bag module connec-
tors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.
• Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3
minutes.
• Always work from the side of or under front passenger air bag module.
1. Remove the glove box. Refer to IP-10
.
2. Remove 2 nuts (through glove box opening) retaining front pas-
senger air bag module to instrument panel crossmember.
3. Disconnect the air bag module electrical connectors.
• For removal/installation of the direct-connect SRS connectors,
refer to SRS-6, "
Direct-connect SRS Component Connectors"
.
4. Remove the instrument panel assembly from the vehicle. Refer
to IP-10
.
5. Remove front passenger air bag module nuts and remove air
bag module from the instrument panel assembly.
CAUTION:
• When servicing the SRS, do not work from directly in front of
air bag module.
• Always place front passenger air bag module with caution
label side facing upward.
• Do not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.
• Do not disassemble air bag module.
• Do not use old nuts after removal; replace with new nuts.
• Do not expose the front passenger air bag module to tempera-
tures exceeding 90°C (194°F).
• Replace the air bag module if it has been dropped or sus-
tained an impact.
• Do not allow oil, grease or water to come in contact with the
air bag module.
• For removal/installation of the direct-connect SRS connec-
tors, refer to SRS-6, "
Direct-connect SRS Component Con-
nectors" .

• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer
to SRS-20, "
SRS Operation Check".
Service Replacement Passenger Air Bag Module
1. Install the front passenger air bag module to the instrument
panel pad assembly.
2. Install the instrument panel assembly. Refer to IP-10
.
3. Connect the front passenger air bag module harness connector to yellow 4-pin service replacement air
bag connector and fasten connector to mounting bracket.
CAUTION:
• Always work from the side of or under front passenger air bag module.
• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer
to SRS-20, "

WIRING HARNESS MODIFICATION
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of the service replacement passenger air bag module.
NOTE:
The wiring harness modification is to be performed only if the vehicle is equipped with the original passenger
air bag which uses direct-connect harness connectors. If the passenger air bag is to be replaced in a vehicle
that has already had the service replacement passenger air bag installed, the wiring harness modification is
not required.
CAUTION:
• Do not attempt to repair or replace damaged direct-connect front passenger air bag module connec-
tors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.
• Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3
minutes.
• Always work from the side of or under front passenger air bag module.
• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer
to SRS-20, "
SRS Operation Check" .
1. Locate the yellow and orange direct-connect passenger air bag module harness connectors.
2. Use wire cutters to cut back both previously used direct-connect passenger air bag module harness con-
nectors from the vehicle wiring harness approximately 50 mm (1.9 in) from the connectors.
3. Remove approximately 150 mm (5.9 in) of the vehicle harness covering from the cut end.

LOW TIRE PRESSURE WARNING SYSTEM
System ComponentINFOID:0000000003532692
System DescriptionINFOID:0000000003532693
BODY CONTROL MODULE (BCM)
The BCM is shown with the lower instrument panel LH removed. The
BCM reads the air pressure signal received by the remote keyless
entry receiver, and controls the low tire pressure warning lamp as
shown below. It also has a self-diagnosis function to detect a system
malfunction.
TRANSMITTER
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
