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 front airbag inflators are de-
signed to provide different rates of airbag inflation
from information provided by the ORC. The ORC will
not detect rollover or rear collisions.
The ORC 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 steering wheel and
column, and knee bolsters. 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.
Also, the ORC turns on the AIRBAG warn-
ing light in the instrument panel for six to
eight seconds for a self-check when the
ignition is first turned on. After the self-
check, the AIRBAG warning light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the AIRBAG warning light either momen-
tarily or continuously. A single chime will sound if the
light comes on again after initial start up.
