SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004784390
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. 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 SRS 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.
• 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 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000004675325
NOTE:
• This Procedure is applied only to models with Inte lligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng 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 pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE 1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. 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.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. 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.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.

2. Without disassembling the hydraulic lines, remove the torque member bolts using power tool. Then repo-
sition the torque member and brake caliper assembly aside with wire. Refer to BR-25 .
CAUTION:
Do not depress brake pedal while brake caliper is removed.
3. Put alignment marks on disc rotor and wheel hub and bearing assembly, then remove disc rotor.
4. Remove wheel sensor from steering knuckle. Refer to BRC-32 .
CAUTION:
Do not pull on wheel sensor harness.
5. Loosen steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so as not to damage ball joint (3) boot using Tool.
CAUTION:
Temporarily leave the outer so cket nut installed to prevent
damage to threads and to pr event the ball joint remover or
suitable tool from suddenly coming off.
7. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
8. Remove cotter pin, then loosen hub lock nut using power tool. CAUTION:
Temporarily leave the hub lock nut inst alled to prevent damage to threads.
9. Separate the drive shaft from the wheel hub and bearing assem- bly by lightly tapping the end of the drive shaft using a hammer
or suitable tool, and then remove hub lock nut.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and
drive shaft cannot be separated after performing the above pro-
cedure.
10. Remove the drive shaft from the wheel hub and bearing assem- bly and support the drive shaft.
CAUTION:
• Do not apply an excessive angle to drive shaft joint when
removing from the wheel hub and bearing assembly,
• Do not excessively extend slide joint.
• Do not allow drive shaft to hang do wn. Support the entire drive shaft.
11. Remove wheel hub and bearing assembly bolts, and then remove splash guard and wheel hub and bear- ing assembly from steering knuckle.
