abs light and humming noise from abs pump

I have a 2001 suburban that the abs light just came on and their is a humming noise that will not stop when the truck is cut off coming from the abs pump (or regulator not sure what it is called). Has anyone experienced this or can offer input?

Pull the ABS Maxi-fuse..this will stop the pump and disable your abs system
