Seat Occupant Sensor: Description and Operation
OCS System
OCS System
The OCS system is found only on the front passenger seat. The front passenger OCS system is comprised of the following: 2 OCS rails (weight
sensors) that are mounted to each side of the seat track; an OCS module (electronic control unit) which is mounted to the electrical bracket underneath
the seat cushion pan. The weight of any occupant or object on the front passenger seat is electronically communicated to the OCS module.
The OCS system is also used for operation of the passenger Belt Minder. To deactivate or reactivate the passenger Belt Minder feature, refer to Seat
Belt Systems or the owner's literature.
The components that make up the OCS system, OCS module, inboard OCS rail and outboard OCS rail are serviced separately.
When the front passenger seat is removed for service, the Zero Seat Weight Test must be carried out after the installation of the front passenger seat.
When a OCS system component is installed new, the System Reset must be carried out after the installation of the front passenger seat. The Zero Seat
Weight Test and/or System Reset must be carried out only as instructed to do so.
