Occupant Classification Sensor - Original Equipment: Removal

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Occupant Classification Sensor (OCS) system components, seat cushion foam pad, bladder with pressure sensor and OCSM  , are calibrated to each other and are serviced as an assembly. If a new OCS  system, OCS  system component or seat cushion foam pad are needed, a new OCS  system service kit (seat cushion foam pad, bladder with pressure sensor and OCSM  ) must be installed as an assembly.
NOTE: To identify between a production OCS system and a service OCS system  (OCS service kit), inspect the electrical connector.  A service OCS  system (OCS  service kit) has the electrical connector glued to the OCSM  . It cannot and should not be disconnected or altered.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
