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 pretensioners (if
equipped), the sag of the seat belt is taken up, the driver air bag (in-
flator) 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 col-
lisions. It is not designed to activate in rear impacts, side impacts,
rollovers, or minor frontal collisions, since it would offer no protec-
tion in those types of accidents.

NOTE:

When 2 or more codes are indicated, the lowest numbered code will appear first.

If a code not listed on the table is displayed, then the SDM is faulty.

Current DTC and history DTC can be identified by lighting and flashing of ªAIR BAGº warning lamp as
follows.
Current DTC is set.
(Abnormality exists at present.)History DTC is set only. (Faulty condi-
tion occurred once in the past but nor-
mal condition is restored at present.)

Current DTC is displayed.History DTC is displayed.
However, if a multiple number of DTC's are set an even one of them is a current DTC, ªAIR BAGº warning
lamp remains on after ignition switch is turned ON. Therefore, it is not possible to identify any of them
as to whether it is a current one or a history one. (But use of scan tool (Tech 1) will make identification
possible.)
