    Hi,
    If you're talking about your ABS Modulator, then I suspect your ABS light is on and there's a code for the ABS Pump Motor? If so, this is a control unit issue. The unit can be rebuilt or replaced to address this.
    If I'm off base here, provide some more info so I can better advise you.
