PRECAUTIONS
Supplemental Restraint System (SRS) “AIR BAG”
Supplemental Restraint System (SRS) “AIR
BAG”
The Supplemental Restraint System “AIR BAG”, used alongwith a seat belt, helps to reduce therisk or severity
of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint System consists
of air bag modules (located in the center of the steering wheel and on the instrument panel on the passenger side), a diagnosis sensor unit, warning lamp, wiring harness and spiral cable. Information necessary to
service the system safely is included in the RS section of this Service Manual.
WARNING:
쐌 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 performed by an authorized NISSAN dealer.
쐌 Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
쐌 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.
NDEL0001
Wiring Diagrams and Trouble Diagnosis
When you read wiring diagrams, refer to the followings:
쐌 GI-10“HOW TO READ WIRING DIAGRAMS”
쐌 EL-12“POWER SUPPLY ROUTING” for power distribution circuit
When you perform trouble diagnosis, refer to the followings:
쐌 GI-34“HOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSIS”
쐌 GI-23“HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”
Check for any Service bulletins before servicing the vehicle.

HARNESS CONNECTOR
Description
Description
HARNESS CONNECTOR (TAB-LOCKING TYPE)
쐌 The tab-locking type connectors help prevent accidental looseness or disconnection.
쐌 The tab-locking type connectors are disconnected by pushing or lifting the locking tabs.
Refer to illustration below.
Refer to the next page for description of slide-locking type connectors.
CAUTION:
쐌 Do not pull the harness or wires when disconnecting the connector.
쐌 Be careful not to damage the connector support bracket when disconnecting the connector.

=NDEL0003S02
쐌 A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.
쐌 The slide-locking type connectors help prevent incomplete locking and accidental looseness or disconnec-
tion.
쐌 The slide-locking type connectors are disconnected by pushing or pulling the slider.
Refer to illustration below.
CAUTION:
쐌 Do not pull the harness or wires when disconnecting the connector.

Inspection
FUSE
쐌 If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
쐌 Use fuse of specified rating. Never use fuse of more than
specified rating.
쐌 Do not partially install fuse; always insert it into fuse
holder properly.
쐌 Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is
not used for a long period of time.
FUSIBLE LINK
A melted fusible link can be detected either by visual inspection or
by feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
쐌 If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of
problem.
쐌 Never wrap outside of fusible link with vinyl tape. Impor-
tant: Never let fusible link touch any other wiring harness,
vinyl or rubber parts.
