OCCUPANT RESTRAINT
CONTROLLER
DESCRIPTION
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. 25).
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),

PT
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.
The microprocessor in the ORC monitors internal
components and the airbag system electrical circuits
to determine the system readiness. If the ORC
detects a monitored system fault, it sends messages
to the instrument cluster over the PCI data bus to
turn ON the airbag warning lamp. A decision algo-
rithm in the ORC microprocessor determines when
the deceleration rate is severe enough to require air-
bag system protection. When the appropriate condi-
tions are met, the ORC sends an electrical signal to
deploy the frontal airbags. The impact sensing device
is an accelerometer that senses deceleration, which
provides verification of the severity of an impact. The
ORC is calibrated for the specific vehicle, and is only
serviced as a unit. The ORC also contains an energy-
storage capacitor. The purpose of the capacitor is to
provide airbag system protection if the impact has
damaged or disconnected the battery. The ORC can-
not be repaired or adjusted, and if damaged or faulty,
must be replaced.
REMOVAL
(1) Open hood.
(2) Disconnect and isolate the battery negative
cable.
(3) Wait two minutes for the system reserve capac-
itor to discharge before servicing any airbag compo-
nents.
(4) Remove the center console (Refer to 23 -
BODY/INTERIOR/CENTER
CONSOLE
-
REMOVAL).
(5) Remove
ORC
module
mounting
nuts
and
ground eyelet, then remove module (Fig. 26).
(6) Disconnect ORC 23-way connector.
(7) Remove ORC from vehicle.
INSTALLATION
(1) Connect ORC connector and ensure that the
connector and all locking tabs are engaged.
CAUTION: USE SUPPLIED NUTS ONLY
(2) Position ORC (arrow pointing forward) in the
console floor bracket (Fig. 26), replace ground eyelet,
and attach the nuts and tighten to 9.6 to 14 N·m (85
to 125 in. lbs.) torque.
NOTE: Place the ground eyelet over the front
(towards the front of the vehicle) weld stud when
reattaching the ORC.
(3) Install center console assembly (Refer to 23 -
BODY/INTERIOR/CENTER CONSOLE - INSTALLA-
TION).
WARNING: DO NOT CONNECT BATTERY NEGATIVE
CABLE YET (Refer to 8 - ELECTRICAL/RESTRAINTS
- DIAGNOSIS AND TESTING - AIRBAG SYSTEM).
(4) Close hood.
(5) Verify vehicle and system operation.
