Occupant Classification Sensor (OCS) System: Notes
WARNING: This page is about a different car, the 2003 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Improper positioning of OCS during assembly may damage OCS components. OCS component failure may result. When positioning OCS and seat cushion frame, ensure OCS is not damaged during procedure.
NOTE:
OCS is found only on right front seat. In addition, OCS is not installed on all models. A white tag having the letters "OCS" will appear under the front of right front seat, identifying seat equipped with OCS.
OCS system components (seat cushion foam pad, bladder with pressure sensor and electronic control unit) are calibrated to each other. OCS system components are not to be installed separately. If OCS system, OCS system component or seat cushion requires being replaced, use OCS system service kit (seat cushion, foam pad, bladder with pressure sensor and electronic control unit) and replace all components as an assembly.
To identify the difference between a production OCS system and a service OCS system (service kit), inspect Electronic Control Unit (ECU) electrical connector. A production OCS system allows the ECU electrical connector to be disconnected. A OCS system service kit ECU electrical connector is glued to ECU; it cannot and should not be altered.
If replacing front passenger seat trim cushion trim cover only, OCS must be zeroed.
