I've been thinking about what you wrote above, and looking through the docs. And, whilst I have a big L plate on my arse (that's UK speak for a learner driver) I just can't see that.
I see one canbus. With etacs at one end, and ev-ecu at the other (and each of them containing 120ohm termination resistors. I see everything else as a slave (or passenger or whatever the term is) on that bus. Obviously bmu has its own network to the cmus and there is some networking going on for chademo. But I don't see the ev-ecu as being a gateway between canbus 1 and 2 because I think there is only one. On the other hand ev-ecu does indeed control the UK-line which outputs on pins 7 and 11 of the diagnostic port. Access to this is probably required for programming and resetting SRS and similar fault codes.
Am I completely wrong?
i think we are all Learners when it comes to the CAN Buss, and many other things these days.
No, the opposite; the only ‘private’ bus not accessible via OBD port are BAT/CHAdeMOn CAN…
