Occupant Classification System (OCS) Sensor - Vehicles With: Multi-Contour Seats: Removal

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
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 reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS service kit is installed. Use a scan tool to carry out the OCS reset command.
NOTE: The cushion heater mat and multi-contour seat cushion adjuster on a front outboard passenger seat are not serviced separately. If a new cushion heater mat or a multi-contour seat cushion adjuster is needed on the front passenger seat, install an OCS service kit equipped with a heater mat or a multi-contour seat cushion adjuster. Failure to follow this instruction may result in incorrect operation of the OCS.
NOTE: OCS components (seat cushion foam pad, bladder with OCSM) are calibrated to each other and are serviced as an assembly. The OCS components are not to be installed separately. If a new OCS, OCS component or seat cushion foam pad are needed, a new OCS service kit (seat cushion foam pad, bladder with OCSM) must be installed as an assembly.
NOTE: Removal steps in this procedure may contain installation details.
