OCCUPANT RESTRAINT CONTROLLER (ORC)
DESCRIPTION
The Occupant Restraint Controller 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.

SIDE IMPACT AIRBAG CONTROL MODULE

DESCRIPTION
Vehicles equipped with side impact airbags use two
side impact airbag control modules. One is located on
each vehicle body B-pillar (Fig. 2).
OPERATION
Each side impact airbag control module serves as
the impact sensor for its seat mounted airbag. The
right side SIACM controls the right seat airbag (Fig.
3). The left side SIACM controls the left seat airbag
(Fig. 3). Each SIACM contains two accelerometers,
both accelerometers must agree in order to deploy
the side airbag. In the event of a side impact the
appropriate SIACM will send a electronic signal to
