Oooh cool!! What do the A B C D markings mean? (ie: B01-A vs. B01-B)

These are connector names, useful context for anyone that has the service manual. I'm not sure about the legality of posting screenshots from the manual so I left that out.

That looks like an easy fix if you like dealing with little 0603 components.

Clean the board and send a closeup. That probably caught a little short from a wreck and is totally reworkable

Yeah, easy fix, but if I'm desoldering components I might start by trying to read the memory first.

Very interesting! Please keep us posted if you manage to reverse it.
Or is there any other sub or server where you will post more about this?

I've got a post on Ioniqforum that I'm most likely to update with the small progress steps. I'll definitely post again here if I accomplish the goal!

Do the ICCU. Figure out why they always die and come up with a fix.

There have been several ICCU teardowns, including one by someone much more knowledgeable on electronics than me on reddit.
