PRECAUTIONS

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

INFOID:0000000009594986

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. Information necessary to service the system safely is included in the SR and SB section 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 SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified 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 Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT 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 three minutes before performing any service.

SYSTEM DESCRIPTION

COMPONENT PARTS

Circuit Breaker

INFOID:0000000009725280

The PTC thermistor generates heat in response to current flow. The

temperature (and resistance) of the thermistor element varies with

current flow. Excessive current flow will cause the element's temper-

ature to rise. When the temperature reaches a specified level, the

electrical resistance will rise sharply to control the circuit current.

Reduced current flow will cause the element to cool. Resistance falls

accordingly and normal circuit current flow is allowed to resume.

*: Always check with the Parts Department for the latest parts information.

Harness Connector

INFOID:0000000009707860

HARNESS CONNECTOR (TAB-LOCKING TYPE)

• The tab-locking type connectors help prevent accidental looseness or disconnection.

• The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s). Refer to the figure

below.

Refer to the next page for description of the slide-locking type connector.

CAUTION:

Do not pull the harness or wires when disconnecting the connector.
