Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001396424
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. 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 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 for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001396425
 Do not use electrical test equipment to check SRS circuits 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 SRS 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 module 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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001282486
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 switch 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
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 Steering SystemINFOID:0000000001282487
 Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming
contaminated by dirt or other foreign matter.
- For easier and proper assembly, place disassembled parts in order on a parts rack.

CHECKING CONDITION OF INSTALLATION
 Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
 Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
 Check steering gear assembly mounting bolts and nuts for looseness. Refer to ST-12, "
Removal and Instal-
lation" .
CHECKING STEERING WHEEL PLAY
 Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
 When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
 Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
 Perform neutral position inspection after wheel alignment. Refer to SR-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
 Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
 Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to
STC-3, "
Work Flow" .
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)

 Check front wheel turning angle after toe-in inspection. Place front
wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
 With the engine at idle, turn steering wheel from full left stop to full
right stop and measure the turning angles.
 Measure rack stroke if angles are outside the specified value. RHD
shown LHD similar.
 Disassemble steering gear assembly to check the cause that rack
stroke is outside of the standard.
 Steering angles are not adjustable. Check steering gear assembly,
steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.
