Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) ªAIR BAGº AND ªSEAT BELT
PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to NISSAN MODEL R20 is as follows (The composition
varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
I For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
WARNING:
I 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 should be per-
formed by an authorized NISSAN dealer.
I Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
I Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTIONS FOR SRS ªAIR BAGº AND ªSEAT BELT PRE-TENSIONERº SERVICE
IDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
I Before servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait at least 3
minutes.
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.
I Diagnosis sensor unit must always be installed with their arrow marks ª +º pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
I 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.
I Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module (built-in type) standing with stud bolt side setting
bottom.
I Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
I After air bag inflates, the front instrument panel assembly should be replaced if damaged.
WIRING DIAGRAMS AND TROUBLE DIAGNOSIS
When you read wiring diagrams, refer to the following:
IGI-10, ªHOW TO READ WIRING DIAGRAMSº
I EL-8, ªPOWER SUPPLY ROUTINGº for power distribution circuit
When you perform trouble diagnosis, refer to the following:
I GI-25, ªHOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSISº
I GI-22, ªHOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENTº

SRS Configuration
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ªONº or ªSTARTº
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal
collision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows:

Seat Belt Pre-tensioner with Load Limiter
The seat belt pre-tensioner system with load limiter is installed to
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a fron-
tal collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified
level occurs, seat belt slack resulting from clothing or other factors
is immediately taken up by the pre-tensioner. Vehicle passengers
are securely 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
twisting of the ELR shaft, and a relaxation of the chest-area seat
belt web tension while maintaining force.
Built-in Type Side Air Bag
Front side air bag is built-in type.
The front seat backs with built-in type front side air bag have the
labels shown in figure at left.
