How the Airbag System Works
• The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. The airbag inflators are designed to
provide different rates of inflation. Based on the level
of collision severity, the ORC determines the proper
rate of inflation. The ORC may modify the rate of
passenger airbag inflation or prevent passenger airbag
deployment based on input from the Occupant Clas-
sification System (OCS). The ORC will not detect
roll-over or rear impacts. Furthermore, the airbags are
not on and will not inflate if the key is in the
OFF/LOCK position, in the ACC position, or not in
the ignition.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the ON/RUN position. These include all of the items
listed under “Airbag System Components,” except the
steering wheel and column and the knee bolsters.
• The ORC turns on the Airbag Warning
Light and Passenger Airbag Disable (PAD)
Indicator Light for six to eight seconds as a
self-check when the ignition is first turned
ON. After the self-check, the Airbag Warning Light
will turn off and the PAD Indicator Light will function
normally (Refer to “Passenger Airbag Disable (PAD)
Indicator Light” in this section). If the ORC detects a
malfunction in any part of the system, it turns on the
Airbag Warning Light either momentarily or continu-
ously. A single chime will sound if the light comes on
again after initial start up.
