PRECAUTIONS

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. The SRS system composition which is available to NISSAN MODELA33 is as follows:

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), seat belt pre-tensioners, a diagnosis sensor unit, crash zone sensor, 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), 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. SRS wiring harnesses can be identified by yellow and/or orange harness connector.

How to Handle Battery

NFSC0003

CAUTION:

I If it becomes necessary to start the engine with a booster

battery and jumper cables, use a 12-volt booster battery.

I After connecting battery cables, ensure that they are

tightly clamped to battery terminals for good contact.

METHODS OF PREVENTING OVER-DISCHARGE

NFSC0003S01

The following precautions must be taken to prevent over-discharging a battery.

I The battery surface (particularly its top) should always be kept

clean and dry.

I The terminal connections should be clean and tight. I At every routine maintenance, check the electrolyte level.

This also applies to batteries designated as “low maintenance” and “maintenance-free”.

I When the vehicle is not going to be used over a long period of

time, disconnect the negative battery terminal. (If the vehicle has an extended storage switch, turn it off.)

MEL041F

MEL042F

I Check the charge condition of the battery.

Periodically check the specific gravity of the electrolyte. Keep a close check on charge condition to prevent over-discharge.

CHECKING ELECTROLYTE LEVEL

NFSC0003S02

WARNING:

Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touching a battery, do not 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.

Sulphation

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 voltage 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 service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.

SPECIFIC GRAVITY CHECK

1. Read hydrometer and thermometer indications at eye level.

2. Use the chart below to correct your hydrometer reading according to electrolyte temperature.

CHARGING THE BATTERY

NFSC0003S04

CAUTION:

I Do not “quick charge” a fully discharged battery. I Keep the battery away from open flame while it is being

charged.

I When connecting the charger,connect the leads first, then

turn on the charger. Do not turn on the charger first, as this may cause a spark.

I If battery electrolyte temperature rises above 55°C (131°F),

stop charging. Always charge battery at a temperature below 55°C (131°F).

Charging Rates

Amps Time

50 1 hour 25 2 hours 10 5 hours

5 10 hours

NFSC0003S0401

Do not charge at more than 50 ampere rate. NOTE:

The ammeter reading on your battery charger will automatically decrease as the battery charges. This indicates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps indicated above refer to initial charge rate.

I If, after charging, the specific gravity of any two cells varies

more than .050, the battery should be replaced.

System Description

CHARGING SYSTEM

System Description

The 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 3 (S) through:

I 120A fusible link (letter A, located in the fuse and fusible link box), and I 10A fuse (No. 70, 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 3 (S) detecting the input voltage. The charging circuit is protected by the 120A fusible link. The alternator is grounded to the engine block. With the ignition switch in the ON or START position, power is supplied

I through 10A fuse [No. 30, located in the fuse block (J/B)] I to combination meter terminal 24 for the charge warning lamp.

Ground is supplied to terminal 68 of the combination meter through terminal 2 (L) of the alternator. With power and ground supplied, the charge warning lamp will illuminate. When the alternator 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.
