REMOVAL
WARNING:
• Before servicing the SRS, turn ignition switch OFF, disconnect bot h battery terminals then wait at
least three minutes.
• Replace the air bag diagnosis senso r unit if any SRS air bag has been deployed or if any front seat
belt pre-tensioner has been deployed.
• Before disconnecting the air bag diagnosis sensor unit harness conn ectors, be sure to disconnect
each harness connector of the front seat belt pre-tensioners (LH/RH) to prevent accidental air bag
deployment by static electricity and seat belt pre-tensioner operation.
• Do not use the air tools or electric tools for servicing.
• When replacing the air bag diagno sis sensor unit, always check with th e parts department for the lat-
est parts information. Installing an incorrect air bag diagnosis sen sor unit may or may not cause the
air bag warning lamp to illuminate and may cause in correct deployment of the supplemental air bags
and seat belt pre-tensioners in a collision resulting in serious personal injury or death.
1. Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) or part
number using CONSULT.
2. Disconnect negative and positive battery terminals, then wait at least three minutes. Refer to PG-70,
"Removal and Installation (Battery)".
3. Remove center pillar lower finisher. Refer to INT-25, "

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012432057
The Supplemental Restraint System such as “A IR 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 inopera tive, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses 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 electri c 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.
