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, it is recommended that all mainte-
nance and repair be performed by an authorized NISSAN/INFINITI dealer.
• Improper repair, 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 or batteries, and wait at least three minutes before performing any service.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000012600948
• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have
passed.
• The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front
of the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
• Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
• After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Front Seat Belt Pre-tensioner INFOID:0000000012600955
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates N
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level O
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the shoulder belt pre-tensioner (1) as well
as the lap belt pre-tensioner (2). Vehicle passengers are securely
P
restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
AWHIA0413ZZ
twisting of the ELR shaft, and a relaxation of the chest-area seat belt web tension while maintaining force.
The air bag diagnosis sensor unit is located under the center con-
sole assembly. The air bag diagnosis sensor unit receives signals
from multiple SRS sensors and controls the deployment of the air
bags. The deployment of the air bags depends on the type and
severity of the collision. The air bag diagnosis sensor unit has self-
diagnosis capability through the use of the CONSULT as well as
flash codes displayed by the air bag warning lamp.
AWHIA0414ZZ
The crash zone sensor is located behind the radiator and under-
neath the front air duct. The crash zone sensor sends signals to the
air bag diagnosis sensor unit during a frontal collision. This sensor
may be identified by a yellow connector.
AWHIA0415ZZ
The rear side air bag satellite sensors are located behind the dash
side lower finisher LH and RH. The rear side air bag satellite sensors
send signals to the air bag diagnosis sensor unit during a side colli-
sion. These sensors may be identified by yellow connectors.
AWHIA0417ZZ
The front door satellite sensors are located in the driver and passen-
ger doors. The sensors detect sudden pressure changes inside the
door cavity and then send signals to the air bag diagnosis sensor
unit during a side collision. These sensors may be identified by yel-
low connectors.
AWHIA0418ZZ
DIRECT CONNECT
The following SRS components use direct-connect style harness connectors.
WHIA0103E

SLIDE DOUBLE LOCKING
• A new style slide double locking type connector is used on certain systems and components, especially
those related to airbag control systems.
• The slide double locking type connectors help prevent incomplete locking and accidental looseness or dis- G
connection.
• The slide double locking type connectors are disconnected by pushing or pulling the slider. Refer to the fig-
ure below. SRC
CAUTION:
• Do not pull the harness or wires when disconnecting the connector.

• The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or
START position.
• The collision modes for which supplemental restraint systems are activated are different among the SRS
systems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-ten-
sioners are activated in a frontal collision but not in a side collision.

The occupant classification system (OCS) identifies different size occupants, out of position occupants, and
detects if a child seat is present in the front passenger seat. The OCS control unit (2) receives inputs from the J
occupant classification sensors (1) (located inside the passenger seat cushion assembly). Depending on clas-
sification of the passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis
sensor unit uses this signal and the seat belt buckle switch (passenger seat) signal to determine deployment
or non deployment of the passenger front air bag in the event of a collision. Depending on the signals K
received, the air bag diagnosis sensor unit can disable the passenger front air bag completely. The OCS
(weight sensors) must be set to zero point using CONSULT after servicing the OCS system.
NOTE: L
• CONSULT can be used to confirm when “zero point reset” for OCS is complete.
• Always perform zero point reset after the removal and installation of the seat or when disconnecting the
OCS control unit harness connector even if zero point reset has been completed in the past.
• If zero point reset is incomplete, the passenger air bag will be disabled and the passenger air bag off indica- M
tor will be ON.
• In case of customer concern, CONSULT can be used to confirm the passenger air bag status (readiness).
