Seat Occupancy Module (SBE)
WARNING: This page is about a different car, the 2001 BMW M5, 2001 BMW 540i, 2001 BMW 530i, and 2001 BMW 525i. However, it is still accessible from the selected car via links, so may be relevant.
Output signals from the passenger-side seat occupancy sensor pad are converted from a varying analog signal to a digital pulse signal by the SBE. This signal is then sent to the air bag control unit to assist it in making deployment decisions. SBE module is located under passenger seat.
