Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951700
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Precautions for Drive ShaftINFOID:0000000009464432
Observe the following precautions when disassembling and assembling drive shaft.
• Joint sub-assembly does not disass emble because it is non-overhaul parts.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and assembling, clean the outside of parts.
• Prevention of the entry of foreign objects must be tak en into account during disassembly of the service loca-
tion.
• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover must be placed over parts.
• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adhering
to parts.
• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.

DescriptionINFOID:0000000009462973
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
• Before performing trouble diagnoses, read the “Work Flow” in each section.
• After repairs, re-check that the problem has been completely eliminated.
• Refer to Component Parts and Harness Connector Locat ion for the Systems described in each section for
identification/location of components and harness connectors.
• When checking circuit continuity, ignition switch should be OFF.
• Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continui ty between harness connectors in more detail, such as when a sub-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.
• Before checking voltage at connectors, check battery voltage.
• After accomplishing the Diagnosis Procedures and Elec trical Components Inspection, make sure that all
harness connectors are reconnected as they were.
How to Follow Test Grou ps in Trouble DiagnosisINFOID:0000000009462974
1. Test group number and test group title
• Test group number and test group title are s hown in the upper portion of each test group.
2. Work and diagnosis procedure • Start to diagnose a problem using procedur es indicated in enclosed test groups.
3. Questions and results • Questions and required results are indicated in test group.
4. Action • Next action for each test group is indicated based on result of each question.

PRECAUTIONS
• Before starting repairs which do not require battery power:Turn off ignition switch.
Disconnect the negative battery terminal.
• If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
• To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
• Dispose of drained oil or the solvent used for cleaning parts in an
appropriate manner.
• Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
• Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
• Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
• Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
