Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NJSC0001The 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 system composition which is available to NISSAN MODEL N16 is as follows (The compo-
sition varies according to the destination and optional equipment.):
+For 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.
+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 theRS sectionof 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, all maintenance should be per-
formed by an authorized NISSAN 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 RS 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 harness connector.

System DescriptionNJSC0009The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 (S) through:
+10A fuse (No. 33, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage. The charging circuit is protected
by the 80A (Gasoline engine models for Europe without daytime light system) or 100A (Except gasoline engine
models for Europe without daytime light system) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 30, located in the fuse block (J/B)]
+to combination meter terminal 1
Ground is supplied to terminal 28 of the combination meter through terminal 3 (L) of the alternator. With power
and ground supplied, the charge warning lamp will illuminate. When the alternator is providing sufficient volt-
age with the engine running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a fault is indicated.

InspectionNJEL0007FUSENJEL0007S01+If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
+Use fuse of specified rating. Never use fuse of more than
specified rating.
+Do not partially install fuse; always insert it into fuse
holder properly.
+Remove fuse for ªELECTRICAL PARTS (BAT)º if vehicle is
not used for a long period of time.

FUSIBLE LINKNJEL0007S02A 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:
+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.
+Never wrap outside of fusible link with vinyl tape. Impor-
tant: Never let fusible link touch any other wiring harness,
vinyl or rubber parts.

CIRCUIT BREAKERNJEL0007S03For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
SEL109W
CIRCUIT BREAKER (PTC THERMISTOR TYPE)NJEL0007S04The 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 tem-
perature to rise. When the temperature reaches a specified level,
the electrical resistance will rise sharply to control the circuit cur-
rent.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.
