Supplemental Restraint System (SRS) AIR BAG and SEAT BELT PRE-TENSIONER

Supplemental Restraint System (SRS) AIR

BAG and SEAT BELT PRE-TENSIONER NGSC0001
The supplemental Restraint System such as AIR BAG and SEAT BELT PRE-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 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), seat
belt pre-tensioners, a diagnosis sensor unit, a crash zone sensor (4WD models), warning lamp, wiring har-
ness and spiral cable.
Information necessary to service the system safely is included in the RS 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, all maintenance must be performed
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, refer to RS-16.
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 (except SEAT BELT PRE-TENSIONER) cov-
ered with yellow insulation either just before the harness connectors or for the complete harness
are related to the SRS.
Wiring Diagrams and Trouble Diagnosis NGSC0002
When you read wiring diagrams, refer to the following:
HOW TO READ WIRING DIAGRAMS, GI-10
POWER SUPPLY ROUTING for power distribution circuit, EL-11
When you perform trouble diagnosis, refer to the following:

How to Handle Battery NGSC0003

CAUTION:
If it becomes necessary to start the engine with a booster GI
battery and jumper cables, use a 12-volt booster battery.
After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
MA
Never add distilled water through the hole used to check
specific gravity. EM

METHODS OF PREVENTING OVER-DISCHARGE NGSC0003S01
The following precautions must be taken to prevent over-discharg- EC
ing a battery.
The battery surface (particularly its top) should always be kept
clean and dry. FE
The terminal connections should be clean and tight.
At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as low maintenance CL
and maintenance-free.

MEL040F
MT
When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle AT
has an extended storage switch, turn it off.)

TF

PD

AX
MEL041F

Check the charge condition of the battery.

Periodically check the specific gravity of the electrolyte. Keep SU

WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not HA
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

MEL043F

Sulphation NGSC0003S0201
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been sulphated, note its volt-
age and current when charging it. As shown in the figure, less
current and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.

CHARGING THE BATTERY NGSC0003S04 MT

CAUTION:
Do not quick charge a fully discharged battery.
Keep the battery away from open flame while it is being AT
charged.
When connecting the charger, connect the leads first, then
turn on the charger. Do not turn on the charger first, as TF
this may cause a spark.
If battery electrolyte temperature rises above 60C (140F),
stop charging. Always charge battery at a temperature
PD
below 60C (140F).

Do not charge at more than 50 ampere rate.
NOTE: RS
The ammeter reading on your battery charger will automatically
decrease as the battery charges. This indicates that the voltage of

 CHARGING SYSTEM
System Description

System Description NGSC0009

The generator provides DC voltage to operate the vehicles electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator. GI
Power is supplied at all times to generator terminal S through:
80A fusible link [letter a, located in the fuse and fusible link box (with KA24DE engine)] or
MA
100A fusible link [letter a, located in the fuse and fusible link box (with VG33E engine)] and
7.5A fuse (No. 36, located in the fuse and fusible link box).
Generator terminal B supplies power to charge the battery and operate the vehicles electrical system. Out- EM
put voltage is controlled by the IC regulator at generator terminal S detecting the input voltage. The charging
circuit is protected by the 80A fusible link (with KA24DE engine) or the 100A fusible link (with VG33E engine).
Ground is supplied to generator terminal E through body ground E203 (with KA24DE engine) or body ground LC
A1 (with VG33E engine).
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 11, located in the fuse block (J/B)]
EC
to combination meter terminal 17 for the charge warning lamp.
Ground is supplied to combination meter terminal 43 through generator terminal L. With power and ground FE
supplied, the charge warning lamp will illuminate. When the generator is providing sufficient voltage 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. CL

Trouble Diagnoses

Trouble Diagnoses NGSC0011

Before conducting an generator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The generator can be checked easily by referring to the Inspec-
tion Table.
Before starting, inspect the fusible link.
Use fully charged battery.
WITH IC REGULATOR NGSC0011S01

SEL338V

NOTE:
If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace faulty
parts with new ones.
MALFUNCTION INDICATOR NGSC0011S02
The IC regulator warning function activates to illuminate CHARGE warning lamp, if any of the following
symptoms occur while generator is operating:
Excessive voltage is produced.
No voltage is produced.
