My ABS light is on all the time. I have been told that the problem is the ABS mod. Read that it could be the wheel speed sensors are dirty and need cleaning. I drive on a dirt road daily so is it possible to be the sensors? If so, how do you clean them?

Thanks

 

I say bad ABS module.
I have never cleaned a sensor and had it stop the codes from coming back.
