Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703109
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 SR 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 SR 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:0000000001703152
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
• 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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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
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 all control units using CONSULT-III.
Precaution for On Board Diagnosis (OBD) System of A/T and EngineINFOID:0000000001703153
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.

ASSEMBLY
e. Attach dial indicator on differential case at converter housing
side.
f. Insert SST into differential side gear from transaxle case side.
g. Move SST up and down and measure dial indicator deflection.
h. Select proper thickness of differential side bearing adjusting
shim. Refer to “Parts Information” for differential side bearing
adjusting shim selection.
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload
i. Remove converter housing from transaxle case.
j. Remove final drive assembly from transaxle case.
k. Remove differential side bearing outer race from transaxle case.
l. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from “Parts Information” on
transaxle case.
m. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT-230, "
Component".
n. Insert SST and measure turning torque of final drive assembly.
•Turn final drive assembly in both directions several times
to seat bearing rollers correctly.
•When old bearing is used again, turning torque will be
slightly less than the above.
•Make sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Select proper thickness of reduction pinion gear adjusting shim using the following procedures.Suitable shim thickness = Dial indicator deflection +
Specified bearing preload
Bearing preload: Refer to AT-345, "
