IMPACT SENSOR
DESCRIPTION
The Airbag System is a supplemental safety device
designed to help protect the driver and passenger
from serious injury, caused by a frontal impact of the
vehicle.
The Occupant Restraint Controller's (ORC) inter-
nal impact sensor provides verification of the direc-
tion and severity of an impact. The sensor is
mounted within the ORC.

OPERATION

The Occupant Restraint Controller (ORC) uses
data collected from it's internal accelerometers to dis-
criminate the direction and severity of an impact.
The ORC will activate power stages internal to the
module in order to deploy the driver and passenger
side airbags once a predetermined threshold has
been exceeded. The ORC is calibrated for a particular
vehicle family and uses an advanced software algo-
rithm to discriminate the severity and direction of
any vehicle event.

DESCRIPTION
The Occupant Restraint Controller (ORC) is also
sometimes referred to as the Airbag Control Module
(ACM). The ORC contains the accelerometer and
energy reserve capacitor. The ORC is mounted on the
tunnel floor pan, forward of the center console.
OPERATION
The accelerometer is located inside the ORC. The
accelerometer provides confirmation of a crash, dis-
criminating severity. The ORC monitors the system
to determine the system readiness. The ORC may
store sufficient energy to deploy the airbags for only
two minutes after the battery is disconnected. The
ORC contains on-board diagnostics, and will illumi-
nate the AIRBAG warning lamp on the cluster when
a fault occurs. The warning equipment is tested for a
few seconds every time the vehicle is started.
