Seat Occupant Sensor: Description and Operation

OCCUPANT CLASSIFICATION SENSOR (OCS)

CAUTION: If only installing a new front passenger seat cushion trim cover, the occupant classification sensor must be rezeroed.

NOTE: It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed or an OCS service kit is installed. A scan tool is used to trigger the active command to carry out rezeroing of the OCS system.

The seat occupant classification sensor (OCS) system is found only on the front passenger seat. The OCS system components (seat cushion foam pad, bladder with pressure sensor and electronic control unit) are calibrated to each other and are serviced as an assembly. OCS system components are not to be installed separately. If installing a new OCS system, OCS system component or seat cushion foam pad, a new OCS system service kit (seat cushion foam pad, bladder, bladder with pressure sensor and electronic control unit) must be installed as an assembly.

If the OCS needs to be serviced or rezeroed, refer to Air Bag Systems.
