Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS00073
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 per-
formed by an authorized NISSAN/INFINITI dealer.

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.

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
harness connectors.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceNHS00074

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 bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.

The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and 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.

Always replace instrument panel pad following front passenger air bag deployment.

Disposal, recycling, and transportation of air bag modules and seat belt pre-tensioners should be per-
formed in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionNHS0009N
Replace occupant classification system control unit and passenger front seat cushion as an assembly.
Refer to Refer to Service Manual .

COLLISION DIAGNOSIS
Revision: 2006 December 2006 FX35/FX45
COLLISION DIAGNOSISPFP:00015
For Frontal CollisionNHS0007T
To repair the SRS, perform the following steps.
When SRS (except the front side air bag and side curtain air bag modules) is activated in a collision:
1. Replace the diagnosis sensor unit.
2. Remove the air bag modules (except the front side air bag modules and side curtain air bag modules), crash zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
3. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
4. Install new air bag modules (except the front side air bag modules and side curtain air bag modules) crash zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
5. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When SRS is not activated in a collision:
1. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When only one front air bag module is activated in a collision:
1. Replace the following components:
–Diagnosis sensor unit
–Crash zone sensor
–Activated front air bag and seat belt pre-tensioner.
2. Check the other SRS components using the table below. (Refer to “SRS is NOT activated”.)
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
3. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
Only one front air bag may inflate a crash, depending on the crash severity and whether the front occupants
are belted or unbelted. This does not indicate improper performance of the system. Perform self-diagnosis to
make sure the entire SRS operates properly.

Tire RotationNES000GO

After rotating the tires, adjust the tire pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:

Do not include the T-type spare tire when rotating the tires.

When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.

Use NISSAN genuine wheel nuts for aluminum wheels.

ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a transmitter or BCM.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
during self-diagnosis depending on control unit which performs CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con- nector, then turn the ignition switch ON.
2. Select “START (NISSAN BASED VHCL)”.
3. Select “BCM” on “SELECT SYSTEM” screen. NOTE:
If “BCM” is not indicated, go to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM” screen.
5. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.

Self-DiagnosisNES000GX
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds.
