PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS003TT
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 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.

IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
Refer to BL-54, "WARNING FUNCTION" in intelligent key system.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.
BCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to unified meter and
A/C amp. with CAN communication line.
Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter
with communication line.
When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" .
SEAT BELT WARNING CHIME
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.
BCM receives seat belt buckle switch signal [seat belt buckle switch (driver side) ON] from unified meter
and A/C amp. with CAN communication line.
BCM detects ignition switch turned ON and seat belt buckle switch (driver side) ON. And then transmits
buzzer output signal (seat belt warning chime) to unified meter and A/C amp. with CAN communication
line.
Unified meter and A/C amp. transmits buzzer output signal (seat belt warning chime) to combination
meter with communication line.
When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
