AIR BAG SYSTEM 10B-3
GENERAL DESCRIPTION
With the air bag system which includes air bags for both the
driver’s and passenger’s sides as well as the seat belt pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) module is deployed
from the center of the steering column and the passenger air bag
(inflator) module from the top of the instrument panel in front of
the front passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement protection
offered by the driver and front passenger seat belts.
The air bag system is designed to activate only in severe frontal
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.

The adapter will also give an idea of whether contact tension is
sufficient, helping to find an open or intermittent open due to poor
terminal contact.
Special tool
(B) : 09932-75010 (Air Bag Driver/Passenger Load Tool)
This tool is used only when called for in this section. It 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 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 for passenger 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 com-
ponent 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.
1. Connector for contact coil and driver air bag (inflator) module
(Located near the base of the steering column)
2. Connector for driver, passenger air bag (inflator) module and driver and
passenger seat belt pretensioners
3. Not used

CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
