Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612911
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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
Do not use electrical test equipmen t 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.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000001612914
NOTE:
This Procedure is applied only to models with In telligent 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 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 all control units using CONSULT-III.
Precaution for Steering SystemINFOID:0000000001327705
In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle
condition, and then check wheel alignment.
Observe the following precautions when disassembling.

POWER STEERING FLUID
Checking Fluid LevelINFOID:0000000001327709
Stop engine before performing a fluid level check.
Ensure that fluid level is between the MAX range and MIN level.
Because fluid level differs within the HOT range and the COLD range, check it carefully.
CAUTION:
Do not overfill the Max level.
Do not reuse any used power steering fluid.
For recommended fluid, refer to MA-9, "
Fluids and Lubricants".
Checking Fluid LeakageINFOID:0000000001327710
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 to 80 ° C (122 to
176 °F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loos en flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-27
.
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemINFOID:0000000001327711
Incomplete air bleeding causes the following. When this happens, bleed air again.
Generation of air bubbles in reservoir tank.
Generation of clicking noise in oil pump.
Excessive buzzing in oil pump. NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from oil
pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times. CAUTION:
Do not allow steering fluid reservoir tank to go below the low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about
three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.
5. If air bubbles and the cloud don't fade, stop engine, hold air bleeding until air bubbles and the cloud fade.
Perform the 2nd and the 3rd procedures again. HOT : Fluid temperatures from 50 to 80
°C (122 to
176 °F)
COLD : Fluid temperatures from 0 to 30 °C (32 to 86 °F)

CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assemb ly, front suspension, axle and steering column.
Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
Check if the mounting bolts for steering gear assembly are loose or not. Refer to PS-17
.
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumfe rence when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-5,
"Wheel Alignment Inspection".
1. Set vehicle to the straight direction, chec k if steering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer so cket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating te mperature. [Make sure temperature of fluid is
approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27, "
On-Vehicle Inspection and Service".
End play of the axle direction for steering wheel : 0 mm (0 in)
