REMOVAL

A non-calibrated Occupant Classification Module

(OCM) is the only component of the Occupant Clas-
sification System (OCS) that is available for separate
service replacement, as outlined in the procedures
that follow. The OCS components of the passenger
side front seat cushion including the cushion frame,
springs, pad, occupant detection bladder, pressure
sensor, seat cushion foam and the OCM are a factory-
calibrated and assembled unit. Once this unit is con-
nected

to

a

vehicle

electrically,

the

calibration

settings are uploaded from the OCM and stored in
the memory of the Airbag Control Module (ACM). If
only the OCM is subsequently replaced, the new,
non-calibrated OCM learns the proper calibration
settings from the ACM after it is connected to the
vehicle electrically.

If any of the remaining OCS components of the

passenger side front seat cushion require replace-
ment, they are serviced only as a factory-calibrated,
assembled, and tamper-evident service replacement
package. This package includes the assembled frame,
springs, pad, bladder, sensor, foam, wiring and a cal-
ibrated OCM. When installing this package, always
replace all of the existing components with the new
components as a unit. Do not attempt to separate or
disconnect any of the new OCS components con-
tained in the service replacement package from each
other, and do not attempt to reuse any of the
replaced components in this or any other vehicle.

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-
ger side front seat cushion unit with another com-
plete service replacement package.
