5. Discard the entire passenger side front seat cushion frame, springs, pad, bladder and pressure sensor, foam,
wiring and Occupant Classification Module (OCM) and replace with the entire contents of the factory-calibrated,
assembled and tamper-evident service replacement package.
INSTALLATION
If any of the Occupant Classification System (OCS) components of the passenger side front seat cushion require
replacement, they are serviced only as a factory-calibrated, assembled, and tamper-evident service replacement
package. This package includes the assembled frame, springs, pad, seat weight bladder and pressure sensor, foam,
wiring and a calibrated Occupant Classification Module (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 contained 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 components except the OCM have been replaced with the service replace-
ment package components, the OCM can only be serviced by replacing the entire passenger side front seat cushion
unit with another complete service replacement package. Any time any one of these components is removed or
replaced for any reason, the OCM must be re-calibrated using a diagnostic scan tool, the Occupant Classification
Seat Weight special tool, and the Occupant Classification System Verification Test. Refer to the appropriate diag-
nostic procedures.
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, occupant classification sys-
tem, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge
before performing further diagnosis or service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
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 sepa-
rately. All other components of the passenger side front seat cushion assembly must be serviced only as a
complete factory-calibrated, assembled and tamper-evident service replacement package. This package
includes the frame, springs, pad, bladder and pressure sensor, foam, wiring and a calibrated 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 in the service replacement pack-
age from each other, and do not attempt to reuse any of the replaced components in this or any other
vehicle. Failure to take the proper precautions could result in failure of the passenger airbag to deploy
when required, or in passenger airbag deployment when not required.
WARNING: To avoid personal injury or death on vehicles equipped with the Occupant Classification System
(OCS), do not modify the front passenger seat assembly or center floor console in any way. Do not use any
prior year, subsequent year, secondary or aftermarket seat trim covers. At no time should any Supplemental
Restraint System (SRS) or OCS component be modified or replaced with any part except those which are
specified for the particular vehicle application in the DaimlerChrysler Mopar Parts Catalog. Failure to
observe these precautions could cause an OCS miscalibration condition, which may result in the passenger
airbag failing to deploy when required or deploying when not required.
CAUTION: On vehicles equipped with the Occupant Classification System (OCS), never replace both the Air-
bag Control Module (ACM) and the Occupant Classification Module (OCM) at the same time. If both require
replacement, replace one. Then perform the supplemental restraint verification test before replacing the
other. Both the ACM and the OCM store 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.
1. Discard the entire passenger side front seat cushion frame, springs, pad, bladder and pressure sensor, foam,
wiring and Occupant Classification Module (OCM) and replace with the entire contents of the factory-calibrated,
assembled and tamper-evident service replacement package.
2. Reinstall the trim cover onto the passenger side front seat cushion. (Refer to 23 - BODY/SEATS/SEAT CUSHION
COVER - FRONT - INSTALLATION).
