WARNING:
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not use air tools or electric tools for servicing.
REMOVAL
1. Disconnect both the negative and positive battery terminal s, then wait at least three minutes. Refer to PG-
73, "Removal and Installation (Battery)".
2. Remove the steering wheel. Refer to ST-31, "Removal and Installation"
.
3. Remove the steering column lower cover and position steering column upper cover aside. Refer to IP-17,
"Removal and Installation".
4. Remove the paddle shifter (if equipped). Refer to TM-382, "Removal and Installation"
.
5. Disconnect the harness connector (A) from the spiral cable and the harness connector (B) from the steering angle sensor.
6. Remove two screws ( ), then remove the spiral cable and steering angle sensor assembly (1).
CAUTION:
Do not turn the spiral cable quickly or beyond the limit
number of turns (approximately 2.5 turns from the neutral
position), this may cause the cable to snap.
7. Separate the spiral cable (1) from the steering angle sensor (2) by removing two screws (A) and releasing three pawls (B).

SPIRAL CABLE
• Do not strike or drop the spiral cable.
• Replace the spiral cable if it has been dropped or sus-
tained an impact.
• Do not disassemble the spiral cable.
• Do not allow oil, grease, detergent or water to come in contact with the spiral cable.
INSTALLATION
Installation is in the reverse order of removal.
• The turn signal lever must be in the neutral position for spiral cable installation.
• Set the spiral cable (1) neutral position by carefully turning the spi-
ral cable (1) clockwise to the end position. Turn the spiral cable (1)
counterclockwise 2.5 turns stopping when the locating pin (C) is at
the top most position, the triangl es (A) are pointing at each other
as shown and the clear window (B) appears white.
NOTE:
If a service part is installed, the neutral position is already set with
a stopper clip in place and should not be adjusted after the stopper
clip is removed. Make sure the stopper is removed before installing
the steering wheel (2).
• During steering wheel (2) installation, make sure the locating pin hole (D) is aligned with the locating pin (C) of the spiral cable (1).
• Perform the neutral position adjustment for the steering angle sen-
sor. Refer to BRC-58, "Work Procedure"
.
CAUTION:
• The spiral cable may snap during steering operation if the spiral cable is installed in an improper
position.
• Do not overturn the spiral cable or go beyond the maximum number of turns allowed. This will cause
the cable to snap.
• The turn signal lever must be in the ne utral position for spiral cable installation.
• Do not apply lubricant to the spiral cable.
• Do not allow oil, grease, detergent or water to come in contact with the spiral cable.
• After the work is completed, check that no system malfunction is detected by air bag warning lamp.
• If a malfunction is detected by the air bag warnin g lamp after repair or replacement of the malfunc-
tioning parts, perform the SRS final check. Refer to SRC-17, "SRS Final Check"
.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009460702
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Precaution for SRS "AIR BAG" and "S EAT BELT PRE-TENSIONER" Service
INFOID:0000000009460703
• Do not use electrical test equipment to check SRS ci rcuits 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 SR S 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 m odule 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.
