did he scan the car to find out it was the module? if not, its common for the wheel bearing to go bad, theres a abs sensor in the hub, when it goes bad the abs light comes on. the abs sensor is built into the hub so you just need a new bearing hub. jack up your car and see if theres any movement when you move the wheel from top to bottom, if one of them have even a little play in them its most likely the one that went bad, and yes you can fix it in your driveway.
or pay a shop to scan it and they can tell you what is exactly wrong with it. most shops charge 100 bucks to do this scan.
