PRECAUTIONS

PRECAUTION

PRECAUTIONS

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

INFOID:0000000003367531

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 AIRBAG” and “SEAT BELT” of this
Service Manual.

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 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 the “SRS AIRBAG”.

• 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

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.

Service

INFOID:0000000003367532

• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3

minutes.
For approximately 3 minutes after the battery negative terminal is removed, it is still possible for the air bag
and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3
minutes have elapsed.

• Diagnosis sensor unit must always be installed with their arrow marks “

⇐

” pointing towards the front of the

vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.

• The spiral cable must be aligned in the neutral position since its rotations are limited. Do not turn steering

wheel and column after removal of steering gear.

• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side

facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.

• Conduct self-diagnosis to check entire SRS for proper functioning after replacing any components.
• After air bag inflates, the front instrument panel assembly should be replaced if damaged.
• Always replace instrument panel pad following front passenger air bag deployment.

Occupant Classification System Precaution

INFOID:0000000003367533

• Replace occupant classification system control unit and passenger front seat cushion as an assembly.

Refer to 

SE-106, "Removal and Installation"

System Description

INFOID:0000000004749730

Supplemental Restraint System (SRS) activates air bag module and seal belt pre-tensioner when it detects a
frontal collision or a side collision that is more than the specified limit. Together with other safety devices, it
reduces the impact that occupant receives when vehicle collision occurs.
Air bag sensor unit supplies power supply to air bag module and pre-tensioner seat belt when deceleration
that is more than the specified limit is detected by G sensor in air bag diagnosis sensor unit, crash zone sen-

SRS AIR BAG SYSTEM

sor, or satellite sensor. Air bag module is composed of electric igniter (squib), filter, pyrotechnic material, and
gas generating material. When air bag module receives a signal from air bag sensor unit, air bag module
ignites pyrotechnic material using electric igniter (squib) so that gas generating material generates high tem-
perature nitrogen gas. The gas through filter activates air bag and seat belt pre-tensioner.

AIR BAG DIAGNOSIS SENSOR UNIT FUNCTIONS

Air bag diagnosis sensor unit has the following functions.
• Detects a collision and supplies the energy for deploying air bag and seat belt pre-tensioner.
• Detects and records electrical malfunction in air bag system and seat belt pre-tensioner system, and blinking

air bag warning lamp.

• Detects and records the deployment of air bag and seat belt pre-tensioner, and turns ON air bag warning

lamp.

• Indicates malfunctioning portion via the number of blinks from the air bag warning lamp in the diagnosis

mode.

• Indicates the malfunction record via CONSULT-III.

COLLISION MODES

The operation of SRS is different depending on the collision modes applications. For example, the driver air
bag module, passenger air bag module, and seat belt pre-tensioner are activated in a frontal collision but not
in a side collision.
