Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EAS000XD

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
with a front 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 C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING: D
q 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 per-
formed by an authorized NISSAN/INFINITI dealer. E
q 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 SRS section. F
q 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 harnesses or
harness connectors.

described in each individual section. H

General Precautions EAS000XF

q Do not operate the engine for an extended period of time without I
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any J
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials. K
Do not smoke while working on the vehicle.

SGI285
L

q Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After M
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
q When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
SGI231

GI-3
PRECAUTIONS

q Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
q If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

PRECAUTIONS

WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness GI
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
B
Precautions for Three Way Catalyst EAS000XG

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions. C
q Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
q When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary. D
q Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three E
way catalyst.
Precautions for Fuel (Unleaded Regular Gasoline Recommended) EAS000XH
F
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
G
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
H
also affect the warranty coverage validity.
Precautions for Fuel (Unleaded Premium Gasoline Required) EAS000XI

Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research I
octane number 96).

If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87 J
AKI number (Research octane number 91) can be used, but only under the following precautions:
q have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium
gasoline as soon as possible. K
q avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance, the use of unleaded premium gasoline is recommended.
L
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
M
also affect the warranty coverage validity.

HOW TO PROBE CONNECTORS
Connector damage and an intermittent connection can result from improperly probing of the connector during
circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the con-
nector, follow the procedures below using a "T" pin. For the best contact grasp the "T" pin using an alligator
clip.
Probing from Harness Side
Standard type (not waterproof type) connector should be probed
from harness side with "T" pin.
q If the connector has a rear cover such as a ECM connector,
remove the rear cover before probing the terminal.
q Do not probe waterproof connector from harness side. Damage
to the seal between wire and connector may result.

SGI841

Probing from Terminal Side
FEMALE TERMINAL
q There is a small notch above each female terminal. Probe each
terminal with the "T" pin through the notch.
Do not insert any object other than the same type male terminal
into female terminal.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

q Some connectors do not have a notch above each terminal. To
probe each terminal, remove the connector retainer to make GI
contact space for probing.

How to Check Enlarged Contact Spring of Terminal H
An enlarged contact spring of a terminal may create intermittent signals in the circuit.
If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con-
tact spring of female terminal.
I
1. Assemble a male terminal and approx. 10 cm (3.9 in) of wire.
Use a male terminal which matches the female terminal.
2. Disconnect the suspected faulty connector and hold it terminal
J
side up.

3. While holding the wire of the male terminal, try to insert the male M
terminal into the female terminal.
Do not force the male terminal into the female terminal with
your hands.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

4. While moving the connector, check whether the male terminal
can be easily inserted or not.

SEL272V

q If the male terminal can be easily inserted into the female termi-
nal, replace the female terminal.

SEL273V

Waterproof Connector Inspection
If water enters the connector, it can short interior circuits. This may lead to intermittent problems.
Check the following items to maintain the original waterproof characteristics.

RUBBER SEAL INSPECTION
q Most waterproof connectors are provided with a rubber seal
between the male and female connectors. If the seal is missing,
the waterproof performance may not meet specifications.
q The rubber seal may come off when connectors are discon-
nected. Whenever connectors are reconnected, make sure the
rubber seal is properly installed on either side of male or female
connector.
