REMOVAL
CAUTION:
• Before servicing, turn the ignition switch OFF, disconnect both battery terminals and wait at least
three minutes.
• Do not use air tools or electric tools for servicing.
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 column covers. Refer to IP-17, "Removal and Installation"
.
3. Rotate steering wheel clockwise to access first combination switch bolt and remove.
4. Rotate steering wheel counter-clockwise to access second combination switch bolt and remove.
5. Disconnect the harness connector from the combination switch and remove.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• After the work is completed, make sure no system malfunction is detected by air bag warning lamp.
• In case a malfunction is detected by the air bag wa rning lamp, reset with the self-diagnosis function
and delete the memory with CONSULT.
• If a malfunction is still detected after the above operation, perform self-diagnosis to repair malfunc-
tions. Refer to SRC-42, "ADDITIONAL SERVICE WHEN RE PLACING CONTROL UNIT : Special Repair

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951571
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 t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009460986
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for WorkINFOID:0000000009460987
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:

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-

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.
Precautions for Drive ShaftINFOID:0000000009464432
Observe the following precautions when disassembling and assembling drive shaft.
• Joint sub-assembly does not disass emble because it is non-overhaul parts.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and assembling, clean the outside of parts.
• Prevention of the entry of foreign objects must be tak en into account during disassembly of the service loca-
tion.
• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover must be placed over parts.
• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adhering
to parts.
• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
