Occupant Classification Sensor (OCS)
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
OCS system components [seat wiring harness, seat cushion foam pad, bladder with pressure sensor and Occupant Classification System Module (OCSM)] are calibrated to each other and are serviced as an assembly. If new OCS system components are needed, an OCS system service kit must be installed as an assembly.
The OCS system is standard equipment on all front outboard passenger seats. For information on diagnosing or servicing the OCS system, refer to the appropriate procedure in SUPPLEMENTAL RESTRAINT SYSTEM article.
