PRECAUTION

PRECAUTIONS

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

INFOID:0000000008461763

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.

Precaution for Battery Service

INFOID:0000000008461764

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000008461765

WARNING:

Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.

Function

Air bag diagnosis sensor unit

• Detects a collision and supplies power supply for deployment to air bag module and 

pre-tensioner seat belt.

• Contains the “G” sensors for both frontal and side collisions and spare battery func-

tion in case of main battery damage in collision.

BCM

Receives the collision detection signal when air bag diagnosis sensor unit detects col-
lision.

Combination meter (air bag warning lamp)

Indicates air bag malfunctioning and deployment by blinking and illuminating air bag 
warning lamp.

Combination switch (spiral cable)

Supplies power supply to driver air bag module on steering wheel.

Crash zone sensor

• Transmits signal to air bag diagnosis sensor unit when a frontal collision occurs.
• Crash zone sensor is a G sensor that outputs voltage signal at the time when a ve-

hicle frontal collision that is more than the specified limit is detected. 

Door-mounted curtain air bag module LH/RH

• Deploys according to collision judgment of G sensor, pressure sensor, and safing 

sensor.

• Receives collision signal from air bag diagnosis sensor unit, ignites, and burns ig-

nition material by electric ignition system, when side collision exceeds setting limit 
of the vehicle. Gas is generated by chemical reaction of ignition material, passes 
filter, and deploys air bag.

• Air bag module mainly consists of air bag and inflator that deploys air bag.

Driver air bag module

• Receives signal from air bag diagnosis sensor unit and deploys air bag.
• In case of frontal collision where acceleration is more than the specified level, the 

ignition materials are ignited by electric ignition system. The system burns the gas 
generating materials resulting in a chemical reaction. This generates hot gases that 
flow into the air bag through a filter and expand the bag.

Front door satellite sensor LH/RH

• Transmits signal to air bag diagnosis sensor unit when a side collision occurs.
• When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor, 

pressure sensor and the safing algorithm to be that of collision which is more than 
the specified level, the driving circuit switches on and feeds the electric ignitor of 
both the side air bag, curtain air bag and pre-tensioner.

Occupant Classification System control unit

Detects passenger seat occupant and judges whether or not passenger seat air bag 
is deployed.

Passenger air bag module

• Receives signal from air bag diagnosis sensor unit and deploys air bag.
• In case of frontal collision where acceleration is more than the specified level, the 

ignition materials are ignited by electric ignition system. The system burns the gas 
generating materials resulting in a chemical reaction. This generates hot gases that 
flow into the air bag through a filter and expand the bag.

Passenger air bag OFF indicator

Indicates whether or not passenger air bag is in the activation mode based on the 
judgement of occupant classification system.

Satellite sensor LH/RH

• Transmits signal to air bag diagnosis sensor unit when a side collision occurs.
• When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor, 

pressure sensor and the safing algorithm to be that of collision which is more than 
the specified level, the driving circuit switches on and feeds the electric ignitor of 
both the side air bag and curtain air bag and seat belt pre-tensioner.

Seat belt buckle switch LH/RH

Controls deployment timing depending on the seat belt condition that is fastened or 
unfastened.
