C0237 Code

[Tahoebigdog03]

Hello I have a strange issue with my ABS light coming on when I hit a bump then the doors unlock and the check engine light blinks but don't stay on. Now and then the service brake system will pop up in the information Center but not always. Also there is loss of power when all this is going on like slow aceleration. This has been going off and on for last few days but like I said its of and on. So today I got the code pulled its C0237 Chevrolet - Erratic Rear Speed Signal.
Thanks guys if anyone knows any suggestions

I’m bumping this thread. I have the same issue and it just started this morning while driving to work. Anyone has any ideas of how to repair this issue?
