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”.

STC-8
< SYSTEM DESCRIPTION >
SYSTEM
When Steering Wheel is Rotated to the Left
The hydraulic routes open from power steering pump to gear housing left side and from gear housing right
side to reservoir tank, providing right direction assist force to the rack.
CONDITIONS FOR HYDRAULIC PUMP ELECTR IC POWER STEERING WARNING LAMP ON
• When the hydraulic pump electric power steering syst em is operating and steering assist force is being gen-
erated, the hydraulic pump electric power steering warning lamp is OFF.
• When the hydraulic pump electric power steering system is stopped by the fail-safe or protective function
and steering assist force is not being generated, the hy draulic pump electric power steering warning lamp
turns ON to inform the driver that t he system is in the manual steering state.
NOTE:
When the hydraulic pump electric power steering system warning lamp turns ON according to the protection
system, the cause is internal high temperature state of the hydraulic pump electric power steering system.
By stopping the engine, internal temperature of the s ystem decreases. After starting the engine, the system
returns to the normal state and the hydraulic pump elec tric power steering system warning lamp turns OFF.
(The system is not malfunctioning.) For informat ion about the protective function, refer to STC-9, "HYDRAU-
LIC PUMP ELECTRIC POWER STEERING SYSTEM : Protection Function".
• When the ignition switch is turned ON, this lamp turn s ON for lamp check (system check). When the system
is operating normally, the lamp turns OFF after the engine starts.
HYDRAULIC PUMP ELECTRIC POWE R STEERING SYSTEM : Fail-safeINFOID:0000000009460345
When an error occurs in the hydraulic pump electric pow er steering system, fail-safe brings the system to a
halt (manual steering) or restricted (constant steering assi st level) state. When the system is in a halt state,
fail-safe turns ON the hydraulic pump electric power steer ing warning lamp to warn the driver that the hydrau-
lic pump electric power steering system is in the manual steering state.

Diagnostic Work SheetINFOID:0000000009460355
Description
• In general, customers have their own criteria for a pr oblem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.
• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
