Occupant Classification System (OCS)
The Occupant Classification System (OCS) is found only on the front passenger seat. The front passenger seat OCS is comprised of a silicone gel-filled bladder mounted between the seat cushion foam and pan. An integrated OCSM with pressure sensor is attached to the bladder by a flexible hose. The integrated OCSM with pressure sensor is mounted to the seat frame. 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 is sensed by the OCS pressure sensor. The OCSM communicates front passenger classification information to the RCM via the HS-CAN. The RCM uses this information when determining if the passenger air bag module is to be deployed in the event of a deployable crash. The RCM also uses this information for Passenger Air Bag Deactivation (PAD) indicator illumination strategy.
The OCSM monitors the OCS for faults.
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 . To deactivate or reactivate the passenger Belt Minder® feature, refer to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES or the Owner's Literature.
