module must be kept with its bag (trim
cover) facing up while being stored or left
standing. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment.
• Observe “Precautions on Handling and
Storage of Air Bag System Components”
for handling and storing it.
Otherwise, personal injury may result.

Installation
1) Install passenger air bag (inflator) module to its
facing cover (2).
CAUTION!
Confirm claw (1) of passenger air bag
(inflator) module hangs in its facing cover (2).

2) Connect passenger air bag (inflator) module
connector (1) securely as shown in figure.
a) Connect connector.
b) Lock connector with lock button (2).
3) Install passenger air bag (inflator) module with its
facing cover (3) to instrument panel at specified
torque as shown.
Tightening torque

21) Wash your hands with mild soap and water
afterward.
NOTE
Remaining steps are to be followed in the
unlikely event that air bag (inflator) module
did not deploy or seat belt pretensioner did
not activate.

22) Ensure that deployment harness has been
disconnected from 12 volts vehicle battery and that
its two banana plugs have been shorted together by
fully seating one banana plug into the other.

The adapter (1) will also give an idea of whether or not
contact tension is sufficient, helping to find an open or
intermittent open due to poor terminal contact. An SDM
short bar release tool (2) is included in the connector test
adapter kit. Inserting it into the SDM connector (3) will
releases the shorting bar.
Special tool
(B): 09932–75010 Air bag driver / passenger load
tool
This tool is used as a diagnostic aid and safety device to
prevent inadvertent air bag (inflator) module deployment.
The load tool has three connectors attached to its case
which are electrically functional and serve as resistive
load substitutions.
No more than two connectors are used at any time.
One of connectors (“STEERING WHEEL”) is used to
substitute the load of the followings.
• Driver air bag (inflator) module when it is connected at
the top of the column to the contact coil assembly.
• Passenger air bag (inflator) module when it is
connected to the air bag harness connector in
instrument panel harness for passenger air bag
(inflator) module.
• Each of driver and passenger seat belt pretensioners
when it is connected to air bag harness connector in
instrument panel harness for driver and passenger
seat belt pretensioners.
• Side-air bag (inflator) module when it is connected to
the floor harness connector for side-air bag (inflator)
module.
• Side curtain-air bag (inflator) module when it is
connected to the floor harness connector for side
curtain-air bag (inflator) module.Another connector (“BASE OF COLUMN”) is used to
substitute the load of the driver air bag (inflator) module
and the contact coil assembly when it is connected at the
base of the column to the air bag wire harness.
The third connector (“PASSENGER INFLATOR”) is not
used.
By substituting the resistance of the load tool when
called for, a determination can be made as to whether an
inflator circuit component is causing system malfunction
and which component is causing the malfunction.
The load tool should be used only when specifically
called for in the diagnostic procedures.
