Otherwise, your first two codes seem to be power supply related, both circuits are on the same fuse, but a wonky Can-bus isn't free from suspicion, your third code is a stuck on/off brake switch, not electrically related, but I could see an installer using the brake switch instead of the park brake switch to enable a head unit's video function.
Ideally I would have liked to know if any other modules had communications DTC.

I beleive it is can bus, but could be wrong. And not sure what you mean by communications dtc.
