Nissan Maxima Service and Repair Manual: Precaution
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and
"SEAT BELT PRE-TENSIONER"
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT
PRE-TENSIONER", used along 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 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 SR and SB 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/INFINITI dealer.
- Improper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury caused by
unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SR section.
- 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.
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 Ignition ON or engine running, DO NOT use
air or electric 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 3
minutes before performing any service.
Service
- Do not use electrical test equipment to check SRS circuits unless
instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both
battery cables and wait at least 3 minutes.
For approximately 3 minutes
after the cables are removed, it is still possible for the air bag and seat
belt pretensioner to deploy. Therefore, do not work on any SRS connectors
or wires until at least 3 minutes have passed.
- Diagnosis sensor unit must always be installed with their arrow marks
"⇐" pointing towards the front of the vehicle for proper operation. Also
check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
- The spiral cable must be aligned with the neutral position since its
rotations are limited. Do not turn steering wheel and column after
removal of steering gear.
- Handle air bag module carefully. Always place driver and front
passenger air bag modules with the pad side facing upward and seat
mounted front side air bag module standing with the stud bolt side facing
down.
- Conduct self-diagnosis to check entire SRS for proper function after
replacing any components.
- After air bag inflates, the front instrument panel assembly should
be replaced if damaged.
- Always replace instrument panel pad following front passenger air
bag deployment.
Occupant Classification System
- Replace occupant classification system control unit and passenger front
seat cushion as an assembly.
Refer to SE-77, "DRIVER SIDE : Disassembly
and Assembly" with climate controlled seat, and SE-134, "DRIVER SIDE :
Disassembly and Assembly" without climate controlled seat.
Precaution for Work
- When removing or disassembling each component, be careful not to damage
or deform it. If a component may be subject to interference, be sure to
protect it with a shop cloth.
- When removing (disengaging) components with a screwdriver or
similar tool, be sure to wrap the component with a shop cloth or vinyl
tape to protect it.
- Protect the removed parts with a shop cloth and prevent them from
being dropped.
- Replace a deformed or damaged clip.
- If a part is specified as a non-reusable part, always replace it
with a new one.
- Be sure to tighten bolts and nuts securely to the specified
torque.
- After installation is complete, be sure to check that each part
works properly.
- Follow the steps below to clean components:
- Water soluble
dirt:
- Dip a soft cloth into lukewarm water, wring the water out of the
cloth and wipe the dirty area.
- Then rub with a soft, dry cloth.
- Oily dirt:
- Dip a soft cloth into lukewarm water with mild detergent
