The dealer will hook it up to their Digital Technician II machine. It is an HD machine that they will only support if you're a dealer.

The machine allows them to manipulate the valves in the ABS module to get any trapped air out. It is the only way that I have heard of getting the brakes bled, IF YOU GET AIR INTO THE ABS MODULE....

I flushed the brake fluid on my ABS bike the other day with a vacuum bleeder. No problems. I made sure not to let the master cylinder run dry and suck any air...
