Occupant Classification Sensor

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The occupant classification sensor uses the high speed CAN for communication with the diagnostic tool and other modules on the high speed CAN. The occupant classification sensor provides the status of the front passenger seat occupant to the RCM system controlling the deployment of the passenger air bag based on sensor input.

Check the high speed CAN circuits between the occupant classification sensor C3159 and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the high speed CAN, damage to the DLC C251, damage to the occupant classification sensor C3159, or a problem in the in-line connector.
