2001 impala ABS light

2001 impala 3.4 4 wheel disk brakes. Constant ABS light brakes still feel good and the car stops..... Help. I don't want to pay through the nose to have an ABS Diagnostic test.

First thing I would do is to check the wiring going to all four ABS wheel sensors , particularly the front ones . The wiring is exposed to anything and everything as you go down the road . Make sure none of it is frayed or broken and properly tie them down . If you type your question into search ( at top of page ) , I'm sure many past posts concerning this will show up . Good luck !
