I have two large pdf documents from Bosch documenting the arrangement of the bit sequences. There is an arbitration section that I presum muust indicate the controller but it may just prioritize messages by content.

Just thought I would take a larger look. It would probably be a lot like looking at brain waves by an amateur.
