PRECAUTIONS

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

INFOID:0000000009750346

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, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, 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, and wait at least 3 minutes before performing any service.

Precautions for Removing of Battery Terminal

INFOID:0000000010200452

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

switch and wait at least 30 seconds.
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.

•  For vehicles with the 2-batteries, be sure to connect the main bat-

tery 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 disconnected, 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:0000000009750347

• 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.

< PRECAUTION >

PRECAUTIONS

- 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.

INFOID:0000000009750354

• 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

INFOID:0000000009750355

• If any malfunction occurs in the system, and control unit detects the malfunction, EPS warning lamp on com-

bination meter turns ON to indicate system malfunction.

• When EPS warning lamp is ON, enters into a manual steering state. (Control turning force steering wheel

becomes heavy.)

EPS SYSTEM : Protection Function

INFOID:0000000009750356

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).
While activating overload protection control, the assist torque gradually decreases, and the steering wheel
turning force becomes heavy. The normal assist torque is recovered if the steering wheel is not turned for a
while.
