PRECAUTIONS
Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELTPRE-TENSIONER” 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 system composition which is available to NISSAN MODEL V10 is as follows (The composition varies according to the destination and optional equipment.):
I For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steering 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).
Information necessary to service the system safely is included in the RS section of this Service Manual.
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 performed 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. For removal of Spiral Cable and Air
Bag Module, see the RS section.
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 Trouble Diagnosis
CAN SYSTEM
I Do not apply voltage of 7.0V or higher to the measurement
terminals.
I Use the tester with its open terminal voltage being 7.0V or less.
Precautions for Harness Repair
CAN SYSTEM
I Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in)]

PRECAUTIONS
I Do not perform bypass wire connections for the repair parts.
(The spliced wire will become separated and the characteristics of twisted line will be lost.)
Wiring Diagrams and Trouble Diagnosis
When you read wiring diagrams, refer to the following:
I Refer to GI-11, “HOW TO READ WIRING DIAGRAMS”
I Refer to EL-12, “POWER SUPPLY ROUTING” for power distribution circuit
When you perform trouble diagnosis, refer to the following:
I Refer to GI-32, “HOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSIS”
I Refer to GI-21, “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)
I The tab-locking type connectors help prevent accidental looseness or disconnection.
I The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s). Refer to the
illustration below.
Refer to the next page for description of the slide-locking type connector.
CAUTION:
Do not pull the harness or wires when disconnecting the connector.

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)
=NLEL0003S02
I A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.
I The slide-locking type connectors help prevent incomplete locking and accidental looseness or disconnec-
tion.
I The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the illustra-
tion below.
CAUTION:
I Do not pull the harness or wires when disconnecting the connector.
I Be careful not to damage the connector support bracket when disconnecting the connector.

FUSE
NLEL0007
NLEL0007S01
I If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
I Use fuse of specified rating. Never use fuse of more than
specified rating.
I Do not partially install fuse; always insert it into fuse
holder properly.
I Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is
not used for a long period of time.
FUSIBLE LINK
NLEL0007S02
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:
I 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.
I Never wrap outside of fusible link with vinyl tape. Impor-
tant: Never let fusible link touch any other wiring harness,
vinyl or rubber parts.
SBF284E
SEL109W
CIRCUIT BREAKER
NLEL0007S03
For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
CIRCUIT BREAKER (PTC THERMISTOR TYPE)
NLEL0007S04
The PTC thermister generates heat in response to current flow.
The temperature (and resistance) of the thermister element varies
with current flow. Excessive current flow will cause the element’s
temperature to rise. When the temperature reaches a specified
level, the electrical resistance will rise sharply to control the circuit
current.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.
