I installed a new exhaust on my car today, and when I started and drove my car, I noticed the ABS light was on. I pulled over and shut the car off, and noticed a loud humming from the ABS unit. The car was 100% off and it was still pumping the ABS or something. I had to pull the fuse to make it stop. Are there any sensors by the exhaust or main cat area that I could have screwed up, or what? I didnt think I hit anything anywhere near my wheel, but what should I check?

 

bump

 

I RANDOMLY get this problem but mine is nothing related to the exhaust, I'm pretty sure its just a bad relay. You should just need to replace it... I have yet to replace mine.

 

This happend to me in my old car. Once I got rid of it the first time it never came back.
