It's not possible to generalize here. I have identified Can-B, Can-C, MOST and LIN bus. Some systems use only one, others use more than one.
For example, transmission uses only Can-C bus. Airbags, Horn, Parktronic use both Can-B and Can-C.
Radio control uses MOST, Can -B and Can-C. Heated seats use Can-B and LIN. It is not simple.
