The p057c code came up as an SES for failed cruise control module. I'm guessing you might have something wired off the TCC/brake switch incorrectly (lol I know you and JorgenSC have gone back and forth on diagrams for this in the other thread).

can't find anything on the p2537

Thanks, I deleted out the first 3. I think we have the TCC wiring figured out, . I don't even have the 4th one in my DTC list in HPTuners. That's odd that it would even come up.
