SMFA, SMBF: driver's seat module and front passenger seat module
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat module (SMFA) and front passenger seat module (SMBF) are common parts. Identification of the driver's seat and/or front passenger seat is implemented via pin coding. The seat modules are bus users on the K-CAN.
Depending on the seat version and optional design, the seat module adjusts and monitors the following functions:
- Seat adjustment
- Seat heating
The seat module evaluates the button signals and activates the required functions. Depending on the seat version and the optional equipment, the seat module is either connected with the switch block (switch block, driver's side or front passenger side seat adjustment) via a line connection or via a LIN bus connection (local interconnect network bus).
