Seat Occupancy Sensor (SBE)

WARNING: This page does not describe the selected car, but rather 151 other vehicles, including the 2006 BMW X5, 2006 BMW M3, 2006 BMW 330Ci, 2006 BMW 325Ci, and 2005 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

The SBE is used as an input to the MRS III control module for detection of a passenger in the right front seat. The MRS III uses the input to determine seat belt tensioner and/or front airbag deployment thresholds.
