Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001404297
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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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 SR 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:0000000001404298
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.
The air bag 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.

WARNING:
When servicing the SRS, do not work from directly in front of air bag module.
Always place air bag module with pad side facing upward.
CAUTION:
Before servicing the SRS, turn ignition switch OFF, discon-
nect both battery cables, then wait at least 3 minutes.
Do not attempt to repair or replace damaged direct-connect
SRS component connectors. If a driver air bag direct-connect
harness connector is damaged, the spiral cable must be
replaced.
Do not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.
Do not disassemble air bag module.
Do not expose the air bag module to temperatures 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.
1. Disconnect the negative and positive battery cables, then wait at least 3 minutes.
2. Remove the covers RH/LH.
3. Place the steering wheel in the straight ahead position.

4. Release the driver air bag module retaining clips RH/LH.
Insert suitable 4mm - 6mm blunt tool (A) through LH access
hole on back side of steering wheel (1) and contact retaining
clip.
CAUTION:
Do not use sharp edged objects such as screwdrivers to
release driver air bag module from steering wheel, SRS
components may be unintentionally damaged.
Press tool inward with sufficient force on retaining clip (1) to
release LH pawl of driver air bag module from steering wheel.
Repeat for RH pawl of driver air bag module from steering
wheel.
Tilt top edge away from steering wheel, then lift upward releas-
ing lower pawl of driver air bag module from steering wheel.
5. Disconnect driver air bag module connector (1) and horn con-
nector (2).
For removal/installation of the direct-connect SRS connectors,
refer to SRC-13, "
CONSULT-III Function (AIR BAG)".
INSTALLATION
Installation is in the reverse order of removal.
For removal/installation of the direct-connect SRS connectors, refer to SRC-9, "
Direct-connect SRS Compo-
nent Connectors".
If driver air bag module is being replaced due to deployment, spiral cable must also be replaced. Refer to
SR-7, "
Removal and Installation".
After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to SRC-
11 , "SRS Operation Check".
