Did some experimentation and it seems like the mode 9 resumes broadcasts according to what I would assume is a "default" scheduling program. My assumption is that it does not assume bus master role in this situation, but haven't been able to investigate further.
I've got a lot more work to do here but I think it's progress. My logger wasn't sending a bus master / heartbeat message before, and once I added that the ccm shut the f up for a whopping 5 seconds before it sent a self-resume announcement, so I think there are things we can learn from this info.

I'll keep plugging away at it when possible. I got a couple hours to experiment tonight, but probably wont see more time with the car until early Tuesday.
