RABS

Was wondering how to go about finding out if my Rabs unit was bad. There’s no abs light only the red brake light, but it goes off after pulling out to drive down the road. But I have no rear brakes, there’s no fluid going to the rear lines. Master cylinder reservoir is full and there are no leaks. Was thinking maybe the rubber flex hose was clogged up idk. Just wondering if there was a way to test the Rabs unit, just to make sure it’s working properly. Thanks any help is appreciated
