PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AHS000HB
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” ServiceAHS000HC

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.
Wiring Diagrams and Trouble DiagnosisAHS000HE
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams" in GI section

PG-3, "POWER SUPPLY ROUTING CIRCUIT" in PG section
When you perform trouble diagnosis, refer to the following:

GI-11, "How to Follow Trouble Diagnoses" in GI section

GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section
Check for any service bulletins before servicing the vehicle.

Removal and InstallationAHS000HW
REMOVAL
CAUTION:

Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3
minutes.

Always work from the side of driver air bag module.
1. Remove the side lids.
2. Remove the right and left side special bolts (TORX bolts).
3. Lift up the driver air bag module.
4. Disconnect the air bag harness connector, and remove the
driver air bag module.
CAUTION:

For installing / removing driver air bag module connector,
insert thin screwdriver wrapped in tape into notch, lift
lock and remove connector.

Install connector with lock raised, and push lock into
connector.

Removal and InstallationAHS000HX
REMOVAL
CAUTION:
Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
1. Remove driver air bag module. Refer to SRS-36, "
Removal and Installation" .
2. Set the steering wheel in the neutral position.
3. Remove steering wheel with steering wheel puller.
CAUTION:
Be careful not to over-tighten puller on steering wheel.
4. Remove the column covers.
5. Loosen the spiral cable fixing screws, and then remove the spiral cable.
CAUTION:

Do not disassemble spiral cable.

Do not apply lubricant to the spiral cable.

6. Disconnect the horn switch connector, and then the spiral cable
connector.
CAUTION:
Do not tap or bump the steering wheel.
7. Remove the wiper washer switch and lighting switch from the spiral cable.
INSTALLATION
Install in the reverse order of removal.
CAUTION:

The spiral cable may snap due to steering operation if the
cable is installed in an improper position.

Also, with the steering linkage disconnected the cable may
snap by turning the steering wheel beyond the limited num-
ber of turns. The spiral cable can be turned counterclock-
wise about 2.5 turns from the right end position.

After the work is completed, perform self-diagnosis to make
sure that no malfunction is detected. Refer to SRS-17, "
SRS
Operation Check" .
