How The Airbag System Works

• The Occupant Restraint Control (ORC) Module de-

termines if a frontal collision is severe enough to
require the airbags to inflate. The front airbag inflators
are designed to provide different rates of airbag infla-
tion from direction provided by the ORC. The ORC
may also modify the rate of inflation based on the

occupant size provided by the Occupant Classification
Module. The ORC will not detect roll over, or rear
impacts.

The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

Also, the ORC turns on the “Airbag Warning
Light” and “PAD Indicator Light” for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the

“Airbag Warning Light” will turn off. The “PAD
Indicator Light” will function normally (Refer to
