PRECAUTIONS

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

INFOID:0000000001612926

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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” 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 “SUPPLEMENTAL RESTRAINT SYSTEM”.

• 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.

Precaution

INFOID:0000000001327568

• Before connecting or disconnecting the BCM harness con-

nector, turn ignition switch “OFF” and disconnect the battery
cable from the negative terminal. Battery voltage is applied to
BCM even if ignition switch is turned “OFF”.

• When connecting or disconnecting pin connectors into or

from BCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are not
any bends or breaks on BCM pin terminals.

nal inspection and make sure whether BCM functions prop-
erly or not. Refer to

Standard"

.

Service Notice or Precaution

INFOID:0000000001327569

• Low tire pressure warning lamp flashes 1min, then turns ON when occurring any malfunction except low tire

WT-22, "CONSULT-III Function (BCM)"

, 

WT-19, "ID Registration Procedure"
