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

INFOID:0000000010072242

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 SR and SB section of this Service Man-

ual.

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.

INSTALLATION

Installation is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Check that the accelerator pedal moves smoothly within the speci-

fied range.

• Check that the accelerator pedal smoothly returns to the original

position.

• Perform an electrical inspection of the accelerator pedal position

sensor. Refer to 

EC-248, "Component Inspection"

 (QR25DE), 

EC-

728, "Component Inspection"

 (VQ40DE).

CAUTION:

• Whenever the harness connector of the accelerator pedal

position sensor is disconnected, perform 

″Accelerator Pedal Released Position Learning″. Refer to

EC-123, "Accelerator Pedal Released Position Learning"

 (QR25DE), 

EC-590, "Accelerator Pedal

Released Position Learning"

 (VQ40DE). 

• Reset the steering angle sensor calibration. Refer to 

BRC-12, "ADJUSTMENT OF STEERING

ANGLE SENSOR NEUTRAL POSITION : Special Repair Requirement"

 (Type 1) or 

BRC-124,

"ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION : Special Repair Require-

ment"

 (Type 2).
