The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes discon -
nected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
switch is in the MAR/ACC/ON/RUN position.
After the self-check, the Air Bag Warning Light
will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continu -
ously. A single chime will sound to alert you if
the light comes on again after initial startup.
The ORC also includes diagnostics that will illu-
minate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the

tently or remains on while driving.
