Occupant Classification System (OCS) Sensor: Removal

WARNING: This page is about a different car, the 2018 Ford Police Interceptor Utility and 2018 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: WARNING: The following procedure prescribes critical repair steps required for correct restraint system operation during a crash. Follow all notes and steps carefully. Failure to follow step instructions may result in incorrect operation of the restraint system and increases the risk of serious personal injury or death in a crash.
NOTE: To prevent system failure, carry out the OCS (occupant classification system) reset when a front passenger seat cushion is disassembled, a new trim cover or heater mat is installed or an OCS (occupant classification system) service kit is installed. Use a diagnostic scan tool to carry out the OCS (occupant classification system) reset command.
NOTE: OCS (occupant classification system) components (seat cushion foam, bladder with OCSM (occupant classification system module)) are calibrated to each other and are serviced as an assembly with an OCS (occupant classification system) service kit. If a new OCS (occupant classification system) or seat cushion foam are needed, a new OCS (occupant classification system) service kit must be installed. The heater mat can be serviced separately.

  11. NOTE: When equipped with an OCS (occupant classification system) service kit, the OCS (occupant classification system) is adhered to the bottom of the front seat cushion foam. This requires the cushion cover, foam and OCS (occupant classification system) to be positioned aside as an assembly.

    Lift the cushion foam. If the cushion foam and OCS are adhered together, then the OCS is a service kit. If nothing is adhered together, then the OCS is original equipment.
