DRIVER AIR BAG MODULE
 Tighten the TORX bolts after completely adjusting the centers of fixing holes on the driver air bag
module side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged
and the module is not installed securely.
 In the case that a malfunction is detected by the air bag warning lamp, after repair or replacement of
the malfunctioning parts, reset the memory by self-diagnosis or by CONSULT-III.
 After the work is completed, check that no system malfunction is detected by air bag warning lamp.

SPIRAL CABLE
6. Remove the spiral cable (1) side pawls (LH/RH).
7. Pull the spiral cable out forward.
CAUTION:
 Never disassemble the spiral cable.
 Never apply lubricant to the spiral cable.
 Never allow oil, grease, detergent or water to come in contact with the spiral cable.
 Never impact the spiral cable.
 Replace the spiral cable if it has been dropped or sustained
an impact.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
 The spiral cable may snap during steering operation if the
cable is installed in an improper position.
The neutral position is set as follows.
 Carefully turn the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and a half turns) and
stop turning at the mark (B) on which the stopper insertion
holes are in the same position.
 The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper is
removed.
 Never over turn the spiral cable or go beyond the number of
turns required. (These will cause the cable to snap.)
 Adjust the spiral cable locating pin (A) to the steering wheel
locating pin hole (C).
 In the case that a malfunction is detected by the air bag warning lamp, after repair or replacement of
the malfunctioning parts, reset the memory by self-diagnosis or by CONSULT-III.

B1049 DRIVER AIRBAG MODULE
DescriptionINFOID:0000000003813957
For driver air bag module, crash is judged by main “G” sensor output signal and safing algorithm in front direc-
tion.
OPERATION
In case of frontal collision whose acceleration exceeds the specified level, the ignition materials are ignited by
electric ignition system. The system burns the gas generating materials resulting in a chemical reaction. This
generates hot gases that flow into the air bag through a filter and expand the bag.
STRUCTURE
Driver air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
Driver air bag module is installed on the center of steering wheel with fixed bolts.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003814141
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 “SRS AIRBAG” and
“SEAT BELT” 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 “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
ServiceINFOID:0000000003814109
 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 battery negative terminal and wait at least 3
minutes.
For approximately 3 minutes after the battery negative terminal is 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 elapsed.
 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 installa-
tion and replace as required.
 The spiral cable must be aligned in the neutral position since its rotations are limited. Do not turn steering
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.
