anchor. The OCM then monitors the return voltage
from each of the sensors. The bladder pressure sen-
sor input allows the OCM to determine whether the
passenger front seat is occupied and the relative size
of the occupant by providing a weight-sensing refer-
ence to the load on the seat cushion. The belt tension
sensor provides an additional logic input to the OCM
microprocessor that allows it to distinguish between
the lower seat belt cinch loads of a belted occupant
and the higher loads associated with a belted child
seat.
Pre-programmed decision algorithms and OCS cal-
ibration allow the OCM microprocessor to determine
when the seat cushion load as signaled by the blad-
der pressure sensor and the seat belt cinch load as
signaled by the belt tension sensor indicate that pas-
senger airbag protection is appropriate. When the
programmed conditions are met, the OCM sends the
proper electronic occupant classification messages
over the PCI data bus to the Occupant Restraint
Controller (ORC), and the ORC enables or disables
the deployment circuits for the passenger front sup-
plemental restraints. The ORC also provides a con-
trol output for the Passenger Airbag Disabled (PAD)
indicator in the instrument panel center stack, based
upon the electronic occupant classification messages
it receives from the OCM.
The OCM microprocessor continuously monitors all
of the OCS electrical circuits and components to
determine the system readiness. If the OCM detects
a monitored system fault, it sets an active and stored
Diagnostic Trouble Code (DTC) and sends the appro-
priate electronic messages to the ORC over the PCI
data bus. Then the ORC sets a DTC and sends mes-
sages to control the airbag indicator operation
accordingly. An active fault only remains for the
duration of the fault, or in some cases for the dura-
tion of the current ignition switch cycle, while a
stored fault causes a DTC to be stored in memory by
the OCM and the ORC. For some DTC's, if a fault
does not recur for a number of ignition cycles, the
OCM will automatically erase the stored DTC. For
other internal faults, the stored DTC is latched for-
ever.
The OCM receives battery current from an IPM
high side driver (Run/Start). The OCM receives
ground through a ground circuit of the body wire
harness, which it shares with the ORC. These con-
nections allow the OCM to be operational whenever
the ignition switch is in the Start or ON positions.
To diagnose and test the OCS, use a scan tool and
the appropriate diagnostic information.
REMOVAL
Once any of the original factory-installed compo-
nents except the Occupant Classification Module(OCM) have been replaced with the service replace-
ment package components, the OCM can only be ser-
viced by replacing the entire passenger front seat
cushion unit with another complete service replace-
ment package (Refer to 23 - BODY/SEATS/SEAT
CUSHION - FRONT - REMOVAL).
WARNING: Never replace both the Occupant
Restraint Controller (ORC) and the Occupant Clas-
sification Module (OCM) at the same time. If both
require replacement, replace one, then perform the
Airbag System test (Refer to 8 - ELECTRICAL/RE-
STRAINTS - DIAGNOSIS AND TESTING - AIRBAG
SYSTEM) before replacing the other. Both the ORC
and the OCM store Occupant Classification System
(OCS) calibration data, which they transfer to one
another when one of them is replaced. If both are
replaced at the same time, an irreversible fault will
be set in both modules and the OCS may malfunc-
tion and result in personal injury or death.
(1) Disconnect and isolate the battery negative
cable.
(2)
WARNING: Wait two minutes for the airbag system
reserve capacitor to discharge before beginning
any airbag system or component service. Failure to
do so may result in accidental airbag deployment,
personal injury or death.
(3) Reach under the front edge of the passenger
side front seat cushion to access and remove the lock
pin from the connector lock tower on the Occupant
Classification Module (OCM) (Fig. 36).
(4) Disconnect the passenger front seat wire har-
ness connector for the OCM.
(5) Remove the two screws that secure the OCM to
the OCM bracket.
(6) Remove the OCM from under the passenger
front seat.
INSTALLATION
WARNING: To avoid personal injury or death on
vehicles equipped with the Occupant Classification
System (OCS), only the Occupant Classification
Module (OCM) and the seat cushion trim may be
serviced separately. All other components of the
passenger front seat cushion must be serviced only
as a complete factory-calibrated, assembled and
tamper-evident service replacement package.
Once any of the original factory-installed compo-
nents except the OCM have been replaced with the
service replacement package components, the OCM
can only be serviced by replacing the entire passen-

PASSENGER AIRBAG
DISABLED INDICATOR
DESCRIPTION
Vehicles equipped with the Occupant Classification
System (OCS) include a Passenger Airbag Disabled
(PAD) indicator (Fig. 40) which is located in the
instrument panel center stack, above the radio. The
PAD indicator is present only in vehicles equipped
with the OCS.The PAD indicator consists of a molded plastic
housing with an integral connector at the back. An
amber Light Emitting Diode (LED) behind the lens
causes the ªPASS AIR BAG OFFº text and icon to
appear silhouetted against an amber field through
the translucent lens when the indicator is illumi-
nated from behind by the LED. The PAD indicator is
available for separate service replacement.
OPERATION
In vehicles equipped with the Occupant Classifica-
tion System (OCS), the Passenger Airbag Disabled
(PAD) indicator gives an indication when the passen-
ger airbag and seat belt tensioner deployment cir-
cuits are disabled by the Occupant Restraint
Controller (ORC). The PAD indicator is controlled by
a transistor within the ORC through a hard wired
output based upon ORC programming and electronic
occupant classification messages received by the ORC
over the Programmable Communications Interface
(PCI) data bus from the Occupant Classification
Module (OCM). The PAD indicator Light Emitting
Diode (LED) is completely controlled by the ORC.
The LED receives a battery current input on the
fused ignition switch output (RUN/START) circuit.
Therefore, the LED will always be OFF when the
ignition switch is in any position except ON or
START. The LED only illuminates when it is pro-
vided a path to ground by the ORC transistor. The
ORC will turn on the PAD indicator for the following
reasons:
²Bulb Test- Each time the ignition switch is
turned to the ON position the PAD indicator is illu-
minated for about six seconds.
²Child Seat Detected Occupant Classifica-
tion Message- Each time the ORC receives a mes-
sage from the OCM indicating a child seat has been
detected in the passenger front seat, the passenger
airbag and seat belt tensioner deployment circuits
are deactivated and the PAD indicator will be illumi-
nated. The indicator remains illuminated until the
ORC receives an occupant classification message
indicating that:
²The passenger front seat is empty.
²The seat is occupied by a load equal to or
greater than a fifth percentile female.
²OR,Until the ignition switch is turned to the
OFF position, whichever of these three occurs first.
²Load Less Than Fifth Percentile Female
Occupant Classification Message- Each time the
ORC receives a message from the OCM indicating
that a load less than a fifth percentile female has
been detected in the passenger front seat, the pas-
senger airbag and seat belt tensioner deployment cir-
cuits are deactivated and the PAD indicator will be
illuminated. The indicator remains illuminated until:

(a) If the heat staked or component seam loca-
tion is loose, hold the two components tightly
together and using a soldering gun with a flat tip,
melt the material securing the components
together. Do not over heat the affected area, dam-
age to the exterior of the trim panel may occur.
(b) If the heat staked material is broken or miss-
ing, use a hot glue gun to apply new material to
the area to be repaired. The panels that are being
heat staked must be held together while the apply-ing the glue. Once the new material is in place, it
may be necessary to use a soldering gun to melt
the newly applied material. Do not over heat the
affected area, damage to the exterior of the trim
panel may occur.
(4) Allow the repaired area to cool and verify the
repair.
(5) Install trim panel.
