    Were the ABS lights on when the "box" was connected? If so, then the codes will need to be read out and diagnosed. There is likely a fault in the module, the wheel speed sensors or the wiring, but it will require a diagnosis to know for sure.

    When the ABS module is disconnected you will still have normal braking, you just wont have the ABS functionality. I can't say how much it will cost to fix because the problem has not been determined, this will require a diagnosis. A shop would charge about minimum of an hour to start to look into this type of problem.
