    PRECAUTIONS

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

    INFOID:0000000012199908

    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 AIR BAG” and “SEAT BELT” of this

    Service Manual.

    WARNING:

    Always observe the following items for preventing accidental activation.

    • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

    the event of a collision that would result in air bag inflation, it is recommended that all maintenance

    and repair be performed by an authorized NISSAN/INFINITI dealer.

    • Improper repair, 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 “SRS AIR BAG”.

    • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

    vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness

    connectors.

    PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

    WARNING:

    Always observe the following items for preventing accidental activation.

    • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

    ignition ON or engine running, never use air or electric 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 or batteries, and wait at least 3 minutes before performing any service.

    Precautions for Removing Battery Terminal

    INFOID:0000000012971407

    When disconnecting the battery terminal, pay attention to the following.

    • Always use a 12V battery as power source.

    • Never disconnect battery terminal while engine is running.

    • When removing the 12V battery terminal, turn OFF the ignition

    switch and wait at least 30 seconds.

    • For vehicles with the engine listed below, remove the battery termi-

    nal after a lapse of the specified time:

    NOTE:

    ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal

    is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.

    • After high-load driving, if the vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait

    for at least 15 minutes to remove the battery terminal.

    < PRECAUTION >

    PRECAUTIONS

    • Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.

    • Example of high-load driving

    - Driving for 30 minutes or more at 140 km/h (86 MPH) or more.

    - Driving for 30 minutes or more on a steep slope.

    • For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON

    the ignition switch.

    NOTE:

    If the ignition switch is turned ON with any one of the terminals of main battery and sub battery discon-

    nected, then DTC may be detected.

    • After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

    NOTE:

    The removal of 12V battery may cause a DTC detection error.

    Service Notice or Precautions for EPS System

    INFOID:0000000012199910

    • Check the following item when performing the trouble diagnosis.

    - Check any possible causes by interviewing the symptom and it

    ′

    s condition from the customer if any malfunc-

    tion, such as EPS warning lamp is turned ON, occurs.

    - Check if air pressure and size of tires are proper, the specified part is used for the steering wheel, and con-

    trol unit is genuine part.

    - Check if the connection of steering column assembly and steering gear assembly is proper (there is not

    looseness of mounting bolts, damage of rods, boots or sealants, and leakage of grease, etc).

    - Check if the wheel alignment is adjusted properly.

    - Check if there is any damage or modification to suspension or body resulting in increased weight or altered

    ground clearance.

    - Check if installation conditions of each link and suspension are proper.

    - Check if the battery voltage is proper.

    - Check connection conditions of each connector are proper.

    - Before connecting or disconnecting the EPS control unit harness

    connector, turn ignition switch “OFF” and disconnect battery

    ground cable. Because battery voltage is applied to EPS control

    unit even if ignition switch is turned “OFF”.

    - When connecting or disconnecting pin connectors into or from

    EPS control unit, take care not to damage pin terminals (bend or

    break).

    - When connecting pin connectors, make sure that there are no

    bends or breaks on EPS control unit pin terminal.

    • During quick steering, rasping noise may be heard from around the

    steering wheel. This is not a malfunction. The noise is an operating

    noise of the EPS system under normal conditions. If the rasping

    noise occurs during slow steering, this may not be an operating

    noise of the system. In this case, it is necessary to find out the

    location of the noise and repair, if necessary.

    EPS SYSTEM : System Description

    INFOID:0000000012199917

    • EPS control unit performs an arithmetical operation on data, such

    as steering wheel turning force (sensor signal) from the torque

    sensor, vehicle speed signal, etc. Then it generates an optimum

    assist torque signal to the EPS motor according to the driving con-

    dition.

    • In case of an error in the electrical system, the fail-safe function

    stops output signals to the EPS motor. Refer to

    STC-8, "EPS SYS-

    TEM : Fail-Safe"

    .

    • EPS control unit decreases the output signal to EPS motor while

    extremely using the power steering function (e.g., full steering)

    consecutively for protecting EPS motor and EPS control unit

    (Overload protection control). Refer to

    STC-8, "EPS SYSTEM :

    Protection Function"

    .

    • Extensive steering at low speed will cause the EPS control unit

    and EPS motor to heat up, once temperature reaches critical point

    EPS control unit will reduce current to reduce heat up. System will

    recover as temperature lowers (reduced or no assistance).

    • In SPORT mode, changes the steering assist characteristic to

    enhance a stable steering feel according to the mode signals from

    multi display unit via CAN communication. (Models with Integrated

    Control System)
