By bogus, I can not find the codes documented anywhere, including the factory repair manual. If the codes will show for all Odyssey and some other models, then maybe the issue is that Honda did not document them.
Wonder what a HDS uniti would find? In the repair guide, it does cover 12-10, so if one should only take documented codes into consideration, then fine.
The 71-34 code is interesting in that there is a documented 81-34 code with same/similar description.
