System Diagram - Supplemental Restraint System (SRS): OCS

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The OCS is found only on the front passenger seat. The OCS classifies the size of the front passenger seat occupant and provides this information to the RCM . The RCM uses this information (and other inputs) in determining the deployment strategy of the passenger air bag, adaptive load limiter, and passenger seat side air bag and pretensioners. The OCS is comprised of:

a silicone gel-filled bladder mounted between the seat cushion foam and seat pan
an OCSM with an integrated pressure sensor, attached to the seat frame
a BTS , which is hard-wired to the OCSM

Pressure is applied to the OCS bladder when weight of any occupant or object in the front passenger seat is present. The pressure is then transferred through a tube and sensed by the OCS pressure sensor within the OCSM. The OCSM and pressure sensor is mounted to a bracket underneath the seat cushion pan and is serviced as a kit with the seat cushion and heater mat (if equipped). The OCSM sends information concerning the weight of any occupant or object on the front passenger seat to the RCM via the HS-CAN . The RCM uses this information when determining if the passenger air bag module needs to be deployed in the event of a crash.

The OCS is also used for operation of the passenger Belt-Minder®. For information on the passenger Belt-Minder® feature, REFER to SAFETY BELT SYSTEM - 1ST ROW , Belt-Minder. To deactivate or reactivate the passenger Belt-Minder® feature, REFER to BELT-MINDER® DEACTIVATING/ACTIVATING or the Owner's Literature.
