SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Revision: 2005 July 2005 FX
Front Seat Belt Pre-Tensioner with Load LimiterAHS000HI
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.
Front Side Air BagAHS000HJ
Front side air bag is built-in type.
The front seatbacks with built-in type side air bag have the labels as
shown.
Side Curtain Air BagAHS000HK
The side curtain air bags have the labels as shown.

deformities, dents, cracks or rust. If it shows any visible
things of damage, replace with new one.

Replace diagnosis sensor unit if it has been dropped or
sustained an impact.
INSTALLATION
Install in the reverse order of removal.
CAUTION:

Check the diagnosis sensor unit for proper installation.

After replacement of diagnosis sensor unit, perform self-diagnosis to make sure that no malfunc-
tion is detected. Refer to SRS-17, "
SRS Operation Check" .

COLLISION DIAGNOSIS
Revision: 2005 July 2005 FX
COLLISION DIAGNOSISPFP:00015
For Frontal CollisionAHS000I6
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-17, "
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-17, "
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-17, "
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.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ADS000RH
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.
PrecautionsADS000RI

Before connecting or disconnecting the AWD control unit
harness connector, turn ignition switch “OFF” and discon-
nect battery ground cable. Because battery voltage is
applied to AWD control unit even if ignition switch is turned
“OFF”.

When connecting or disconnecting pin connectors into or
from AWD control unit, take care not to damage pin termi-
nals (bend or break).
When connecting pin connectors, make sure that there are
no bends or breaks on AWD control unit pin terminal.

Before replacing AWD control unit, perform AWD control
unit input/output signal inspection and make sure whether
AWD control unit functions properly or not. Refer to TF-20,
"AWD Control Unit Input/Output Signal Reference Values" .
