Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Usually this is a bad wheel speed sensor or wiring to the wheel speed sensor to one of the front wheels. Did you get the codes with an abs scan tool?
did you check the wiring that runs to each of the wheel speed sensors? The are common for breaking around the lower control arm where it bends. Then you need to check power and ground to the module then check the data line. If those are good, then you have a dead module.
Of course, until you get it scanned these are just guesses. Thats why the light is ON, so we dont need to guess.
I cant tell you right now if it will expensive or not...
