They're nearly all "lost communication" or "screwed up data" codes. You could have an overall power problem.
Are you still on the original battery?

changed both batteries without aux power hookup dealership said this messed with computer . They reset that, wiped all codes good to go right Nope all good all day out to dinner no power steering track control abs sway bar windshield wipers come on almost wreck not happy

That many codes at once could also be a failed PCM.

If the dealer reset the PCM that would not necessarily fix it.

Did you not have any codes before the battery swap?

When you get that many codes step 1 is to clear all of them and see what comes back. Could also point to a power supply problem. Might need a new battery

I am experiencing this exact issue now and this will be by 4th trip back to the dealer. Anybody know how this turned out in the end?
