PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AGS000L7
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 Necessary for Steering Wheel Rotation After Battery Disconnect
AGS000R7
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-II 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-II.

Precautions for Steering System
AGS000CD
●
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
PFP:KLF20
Checking Fluid Level
AGS000CH
●
Stop engine before performing a fluid level check.
●
Ensure that fluid level is between the MAX range and MIN
range.
●
Because fluid level differs within the HOT range and the COLD
range, check it carefully.
CAUTION:
●
Do not overfill the Max range.
●
Do not reuse any used power steering fluid.
●
Recommended fluid is Genuine NISSAN PSF or equivalent.
Checking Fluid Leakage
AGS000CI
Check the lines for improper attachment and for leaks, cracks, dam-
age, 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 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
6.
Check steering gear boots for accumulation of power steering fluid indicating a steering gear leak.
Air Bleeding Hydraulic System
AGS000CJ
Incomplete air bleeding causes the following to occur. 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.
