Occupant Classification Sensor (OCS) System

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The occupant classification sensor (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 the underside of each side seat track; an occupant classification system module (OCSM) 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 OCSM.

The OCS system 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 INSTRUMENT CLUSTER (IC), MESSAGE CENTER, AND WARNING CHIMES or the Owner's Literature.

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 an 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. For information on the Zero Seat Weight Test and/or System Reset, refer to Occupant Classification Sensor (OCS) System Zero Seat Weight Test or Occupant Classification Sensor (OCS) System Reset .

In the event of a deployable crash, a new passenger seat track with OCS weight sensor bolts must be installed. Before carrying out the OCS System Reset, on-demand DTC B1193:00 must be cleared from the OCSM.

The OCS weight sensor bolts are serviced as an assembly (2 weight sensor bolts and mounting bracket per side), the OCSM is serviced separately.
