It means that the ABS control module has detected a problem in the ABS system. That will be impossible to determine without talking to the module with a scan tool to find out why it turned the light on. The other thing that it means is that you do not have ABS, but you now have conventional brakes. The ABS part of the brakes will not work until the problem is found out and fixed.
Check the fuse first...start simple and cheap.
