PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951730
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. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent 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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Service Notice and Precautions for Hydrau lic Pump Electric Power Steering System
INFOID:0000000009460340
• Check each tire for proper air pressure and size. Refer to WT-60, "Tire".
• Verify that the steering system components are G enuine NISSAN parts and have been installed properly.
• Check the steering column for loose mounting bolts.
• Check the steering gear assembly for loose mounting bolts. Check the inner sockets and outer sockets for
damage or wear. Inspect the boots and seals for leakage of power steering fluid.
• Verify proper wheel alignment. Refer to FSU-7, "Inspection and Adjustment"
.
• Check for any damage, wear, or modification to the suspension and body that would result in increased
weight or an improper wheelarch height. Refer to FSU-26, "Wheelarch Height (Unladen*
1)".
• Check for proper battery voltage.
• Verify that all power steering pump assembly connections are clean and fully seated.
• Verify that only Genuine NISSAN E-PSF is used. Use of any power steering fluid other than Genuine NIS-
SAN E-PSF will prevent the power st eering system from proper operation.
• An audible high pitch noise may be heard from the engine compartment when the steering wheel is oper-
ated, particularly at low speeds such as a parking lot maneuver. This condition is not a malfunction, rather
normal system operation. Steering at low speeds or parking lot maneuvers demands higher hydraulic assis-
tance, resulting in larger power st eering pump load and increased system noise.
• The power steering pump is electrically controlled by the power steering control module.
• Before connecting or disconnecting the power steeri ng control module harness connectors, turn ignition
switch “OFF” and disconnect battery ground cable. Batter y voltage is applied to power steering control mod-
ule even if ignition switch is turned “OFF”.

Power Steering Oil Pump AssemblyINFOID:0000000009460343
The power steering oil pump assembly is primarily composed of the
reservoir tank (1), power steering oil pump (2), power steering motor
(3), and power steering control module (4).
RESERVOIR TANK
Fluid is filled from the reservoir tank.
POWER STEERING OIL PUMP
The power steering oil pump is driven by the power steer ing motor and generates hydraulic oil pressure in the
system.
POWER STEERING MOTOR
The power steering motor is controll ed by the power steering control module and drives the power steering oil
pump.
POWER STEERING CONTROL MODULE
By receiving steering angle sensor signal and vehicle speed signal, the power steering control module calcu-
lates hydraulic pressure of the hydraulic pump electric power steering system according to the driving condi-
tions. The power steering control modul e controls the power steering motor.

HYDRAULIC PUMP ELECTRIC POWER ST EERING SYSTEM : System Description
INFOID:0000000009460344
• The system is composed primarily of the power steeri ng oil pump assembly (power steering control module,
power steering motor, power steering oil pump, and reservoir tank), hydraulic pipes, and steering gear
assembly.
• The power steering control module controls the speed of the power steering motor according to the vehicle
speed and steering angle speed. By changing the power st eering oil pump flow, the power steering control
module controls the steering assist force.
• According to the power steering motor control, the sy stem hydraulic pressure is transmitted from the power
steering motor to power steering oil pump. The power steering oil pump is driven by the system hydraulic
pressure.
• After engine start, the hydraulic pump electric power steering system performs control.
• When a malfunction occurs in the system, the fail-safe function stops the hydraulic pump electric power
steering system (manual steering state) or restricts it s operation (certain steering assist force). Refer to STC-
8, "HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM : Fail-safe".
• When the power steering function is used continuously in an extreme manner, the protective function
reduces the output to the power steering motor. Refer to STC-9, "HYDRAULIC PUMP ELECTRIC POWER
STEERING SYSTEM : Protection Function".

When the steering angle speed is high or the vehicle speed is low,
force is generated by increasing discharge amount from the power
steering oil pump and by raising system hydraulic pressure.
OPERATION PRINCIPLE
When Steering Wheel is in the Neutral Position
Because the hydraulic routes open at the power steeri ng pump, gear housing right side, gear housing left side,
and reservoir tank, the hydraulic pressure applied to the right side and left side of the gear housing is equal
and no steering assist force is generated.
When Steering Wheel is Rotated to the Right
The hydraulic routes open from power steering pump to gear housing right side and from gear housing left
side to reservoir tank, providing left direction assist force to the rack.
