Default Both xenon control units bad?

Well, I have had this headlight issues for some time now. Had a chance to look at it today using the WIS wiring diagram. Here is where I am at:

1. Grounds to each headlight are good
2. Headlights are getting power from the relay
3. Switch test out good
4. Bulbs are pretty much brand new
5. Xenon fault light on dash and neither light works

Going through the WIS step by step diagnostic guide it ends up at the "oragne relay", they call it the "filament monitor." My car does not have this relay. Is it possible that both the control units are bad and go bad at the same time? I don't know where else to look.
