A non-calibrated Occupant Classification Module (OCM) is the only component of the Occupant Classification 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 occupant detection bladder, pressure sensor, seat cushion foam and the OCM are a factory- calibrated and assembled unit. Once this unit is connected to a vehicle electrically, the calibration settings are uploaded from the OCM and stored in the memory of the 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 replacement, they are serviced only as a factory-calibrated, assembled, and tamper-evident service replacement package. This package includes the assembled bladder, 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 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 replacement package components, the OCM can only be serviced by replacing the entire passenger side front seat cushion unit with another complete service replacement package.

To avoid serious or fatal injury on vehicles equipped with , disable the Supplemental Restraint System (SRS) before attempting any , steering column, airbag, Occupant Classification System (OCS), 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 SRS. Failure to take the proper precautions could result in accidental airbag deployment.

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 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 bladder, 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 package 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.
