Airbag System Components
The airbag system consists of the following:
•ACM (Airbag Control Module)
•AIRBAG Readiness Light
•Driver and Passenger Front Airbags
•Optional Driver and Passenger Side Airbags.
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Crash Sensors
•Knee Impact Bolsters
The side airbag system, on vehicles so equipped, consists
of the following:
•AIRBAG Readiness Light
•Side Airbag in the Driver’s Seat
•Side Airbag in the Passenger’s Seat
•ACM (Airbag Control Module)
•SIACM (Side Impact Airbag Control Module)
•Interconnecting Wiring
How the Frontal Airbag System Works
•
The front airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect side, roll
over, or rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in the OFF position, in
the ACC position, or not in the ignition, the airbags are
not on and will not inflate.
•The airbag control module also turns on the
AIRBAG light in the instrument panel for 6 to
8 seconds when the ignition is first turned on,
36 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•The side impact airbag control module monitors the
readiness of the electronic parts of the system when-
ever the ignition switch is in the “START” or “RUN”
positions. These include all of the items listed above
except for the AIRBAG light (which is controlled by
the frontal airbag system).
•In moderate to severe side collisions, the side airbag
inflator on the crash side of the vehicle is triggered,
releasing a quantity of nontoxic gas. The inflating side
airbag exits through the seat seam into the space
between the occupant and the door. The side airbag
moves at a very high speed and with such a high force,
that it could injure you if you are not seated properly,
or if items are positioned in the area where the side
airbag inflates. This especially applies to children.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbag is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the airbag covers. Do not modify the
front bumper or vehicle body structure.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee impact bolsters.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
