The Occupant Restraint Controller (ORC) is also
sometimes referred to as the Airbag Control Module
(ACM). The ORC is mounted on the tunnel floor pan,
between the transmission shifter and parking brake
(Fig. 17).
The ORC contains a microprocessor, the impact
sensing device, and energy storage capacitors. The
microprocessor contains the airbag system logic. The
airbag system logic includes On-Board Diagnostics
(OBD) capability, and communicates with the instru-
ment cluster circuitry on the Programmable Commu-
nication Interface (PCI) data bus to control the
airbag indicator lamp.

OPERATION

The impact sensing device is located inside the
ORC. The sensing device provides crash severity dis-
crimination and confirmation of a crash. The ORC
monitors the system to determine the system readi-
ness. The ORC contains on-board diagnostics (OBD),
and will illuminate the AIRBAG warning lamp on
the cluster when a fault occurs. The warning indica-
tor is illuminated for six to eight seconds every time
the vehicle is started.
