You need to get the abs scanned to see what if any sensor is bad/broken wire etc. A pro will have to do this as auto parts scanners don't work. It could also be a normal brake problem as well but get scanned first.

Hello, I have what I believe is a Bosch 2U ABS system on my 93' Chevy Caprice. About a year ago 175k during winter in slushy conditions I noticed the ABS light on dash coming on and the system failed to function. It started working again, but then finally failed and light is permanently on. I checked code in system and it says code 61-faulty pump motor relay or faulty pump motor. What procedure would you follow to troubleshoot the cause?-(I'm pretty handy and have a couple test meters.) Should I start by cleaning up corrosion/checking connections?
