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 SRC 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 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 SRC 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 Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000001099647

NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

Use the Intelligent Key or mechanical key to turn the ignition switch to the

″

ACC

″

position. At this time, the

steering lock will be released.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

Perform the necessary repair operation.

When the repair work is completed, return the ignition switch to the

″

LOCK

″

position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

Perform a self-diagnosis check of all control units using CONSULT-III.

Precautions for Drive Shaft

CAUTION:

Note the following precautions when disassembling and assembling drive shaft.
• Joint sub-assembly does not disassemble because it is non-overhaul parts.

• Perform work in a dust-free location.
• Before disassembling and assembling, clean the parts.
• Prevent the entry of foreign objects during disassembly of the service location.
• 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.
