Steering column switch cluster: Notes
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 steering column switch cluster is a mechanical and electrical interface from the steering wheel to the vehicle. The steering column switch cluster has a fixed mechanical connection to the steering column. Over and above this purely mechanical connection, the steering column switch cluster is electrically connected via local interconnect network bus systems or directly to components.
The steering column switch cluster is no longer a control unit . Depending on the series, the steering column switch cluster is connected through two local interconnect network buses to the following component:
- e.g. F15, I12, F45, F56: Body Domain Controller (BDC)
- E.g. F25: Junction Box Electronics (JBE)
- E.g. F30: Front Electronic Module (FEM)
The multifunction steering wheel is equipment-dependent: e.g. steering wheel heating telephone or speech input system.
