PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EIS001F1

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.
G
Service Notice EIS001EX

q When removing or installing various parts, place a cloth or padding on the vehicle body to prevent

q Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil
or damage them.
q Apply sealing compound where necessary when installing parts. BL
q When applying sealing compound, be careful that the sealing compound does not protrude from parts.
q When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
J
vention measures.
Wiring Diagrams and Trouble Diagnosis EIS001F2

When you read wiring diagrams, refer to the following: K
q Refer to GI-13, "How to Read Wiring Diagrams" .
q Refer to PG-8, "POWER SUPPLY ROUTING" for power distribution circuit.
L
When you perform trouble diagnosis, refer to the following:
q Refer to GI-9, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
q Refer to GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident" . M

Customer Interview
H
Interview the customer, if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customers comments; refer to BL-9, "DIAGNOSTIC WORKSHEET" . This information is necessary to dupli-
cate the conditions that exist when the noise occurs BL
q The customer may not be able to provide a detail description or location of the noise. Attempt to obtain all
the facts and conditions that exist when the noise occurs (or does not occur).
q If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the costumer J
is concerned about. This can be accomplished by test driving the vehicle with the costumer.
q After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when K
defining the noise.
