The MFSW ony uses one Lin Bus and the dedicated CCS Line to the ECU.
Over the Lin Bus all information regarting Buttons for Radio/CCS and BoardComputer are transfered to the BCM.
The BCM than transferes this information to the different CAN Busses and from there to the other ECU's.
The dedicated CCS Line is only a 0V 12V (10V) signal which is in parallel to the CCS information's on the Lin Bus.
But only CCS On/Off is via this dedicated line as a second Channel for Safety reasons transfered.
Speed UP/Down etc. is only Lin and than Can ...
