DESCRIPTION AND OPERATION

OCCUPANT RESTRAINT CONTROLLER (ORC)

DESCRIPTION
The Occupant Restraint Controller (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.
CLOCKSPRING
DESCRIPTION
The clockspring is mounted to the steering column
behind the steering wheel. The clockspring is used to
maintain a continuous electrical circuit between the
wiring harness and the:
• Driver's airbag module
• Speed control switches
• Horn switch
