PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000003788319

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 for Steering System INFOID:0000000003788320

• 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.
• Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with
their operation.
• Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable solvent.
• Before assembly, apply a coat of recommended Genuine NISSAN PSF or equivalent to hydraulic parts.
Petroleum jelly may be applied to O-rings and seals. Do not use any grease.
• Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during installation. Per-
form functional tests whenever designated.

Use HOT range for fluid temperatures of 50° – 80°C (122° – 176°F).
Use COLD range for fluid temperatures of 0° – 30°C (32° – 86°F).
CAUTION:
• Do not overfill.
• Do not reuse any used power steering fluid.
• Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-10, "Fluids and Lubricants".

LGIA0021E

Checking Fluid Leakage INFOID:0000000003788325

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° – 80°C (122° –
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.) SGIA0506E

4. If fluid leakage at connections is noticed, then loosen 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 ST-10.
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic System INFOID:0000000003788326

Incomplete air bleeding causes the following. When this happens, bleed air again.
• Air bubbles in reservoir tank.
• 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 MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds.
Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud-
iness does not exist.

CHECKING CONDITION OF INSTALLATION

• Check installation condition of steering gear assembly, front suspension, axle and steering column.
• Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

End play of the axial direction for steering wheel : 0 mm (0 in)

• Check if the mounting nuts for steering gear assembly are loose.
Refer to ST-17.

LGIA0024E

CHECKING STEERING WHEEL PLAY

1. Turn tires straight ahead, start engine, then turn steering wheel to the left and right lightly, and measure
steering wheel movement on the outer circumference when steering wheel is turned up to the point where
tires start moving.

Steering wheel play on the outer circumference : 0 − 35 mm (0 − 1.38 in)

CHECKING NEUTRAL POSITION ON STEERING WHEEL

• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
5, "Front Wheel Alignment".
1. Turn tires straight ahead, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositioning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of steering outer sockets, then adjust tie-rods by the same amount in the
opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature of 60° – 80°C (140° – 176°F).
4. Tires need to be inflated to specified pressure. Refer to WT-51, "Tire".

2. Start engine. Allow engine to run until tank temperature reaches 50 – 80°C (122 – 176°F).
CAUTION:
• Warm up engine with shut-off valve fully opened. If engine is started with shut-off valve closed,
fluid pressure in power steering pump increases to maximum. This will raise fluid temperature
excessively.
• Be careful not to contact hose with belt when engine is started.
3. With engine at idle, close shut-off valve and read the relief oil pressure.

Relief oil pressure : 9.0 – 9.8 mPa (91.77 – 99.93 kg/cm2, 1305.34 – 1421.37 psi)
CAUTION:
Do not close shut-off valve of pressure gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly.
• If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to ST-27, "Dis-
