I replaced the brake light control switch attached to the pedal to get rid of one of the problems but it didnt work. I can't pass inspection cause of this and dont wanna spend over 1000 on the abs module. Does any know what else it might be

Have the ABS scanned. It is most likely a wheel speed sensor/circuit problem but a scanner is needed for testing!

Do you hear ABS activation at times when stopping and turning the steering wheel? Sounds like a growling noise and the brake pedal kicks back a little. IF turning when this happens, most likely a connector problem. If it does this at any time most likely a sensor problem. Scanner will conform which wheel the problem is at.

I think it does kick back the pedal a little. Ill drive and test it and you said it might be a wheel speed sensor or connector. What kind of connector are you referring to?

Wire connector or plug.
