I could use some help on this one. I’m at ends with this issue and hoping someone can offer some insight. I have an 04 i35 that started with intermittent ABS, tcs, and slip lights and AT check flashing 16 times, then I lost speedometer. The problem became more frequent. Assuming it was a bad ABS module I got one from a salvage yard, installed it, and I’m left with the same problems. Got codes P1574, P1212, and U1001. I saw a post from 2017 that a replacement fixed it, but sadly it’s not that easy in my case. Am I on the right track? Am I just looking to send the one I pulled out for repair? Thanks for any help in advance.
