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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.

Precautions for Steering System

EGS00119

●

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 becom-
ing 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.
Perform functional tests whenever designated.

POWER STEERING FLUID

2006 Pathfinder

POWER STEERING FLUID

PFP:KLF20

Checking Fluid Level

EGS0011D

Check fluid level, referring to the scale on the reservoir tank.
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 power steering fluid.

●

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to

CANTS"

Checking Fluid Leakage

EGS0011E

Check the hydraulic piping lines for improper attachment, leaks,
cracks, damage, loose connections, chafing and deterioration.

Run the engine until the fluid temperature reaches 50

– 80

(122

– 176

F) in the reservoir tank. Keep engine speed idle.

CAUTION:

Do not allow steering fluid reservoir tank to go below the
MIN level line. Check tank frequently and add fluid as
needed.

Turn the steering wheel to the right and left several times.

Hold the steering wheel at each “locked” position for five sec-
onds to check for fluid leakage.

CAUTION:

Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that the oil pump may be damaged.)

If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten
connector as this can damage O-ring, washer and connector. Refer to

PS-20, "POWER STEERING OIL

PUMP"

and

PS-24, "HYDRAULIC LINE"

If fluid leakage from the oil pump is noticed, check the oil pump. Refer to

PS-20, "POWER STEERING

OIL PUMP"

Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.

CAUTION:

Do not reuse copper washers.

Air Bleeding Hydraulic System

EGS0011F

Incomplete air bleeding causes the following:

●

Air bubbles in reservoir tank

●

Clicking noise in oil pump

●

Excessive buzzing in oil pump

When this happens bleed the air again.
NOTE:
When the vehicle is stationary or while the steering wheel is being turned slowly, some noise may be heard
from the oil pump or gear. This noise is normal and does not affect any system.

Check for fluid leakage. Refer to

PS-6, "Checking Fluid Leakage"

Start the engine and turn the steering wheel fully to the 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.

Run the engine at idle speed. Hold the steering wheel at each "locked" position for three seconds.
