I would like to know as well. My SMC II module blew out and I'll be coding a new one (used) in tomorrow and would like to run a diag on it.

Anyway, a common problem with the adaptive headlights is that the stepper motor ball joints get knocked out of place from hitting really bad potholes.

You can open the back cover and pop it back on but it's a bit difficult. I haven't done it myself but I read that someone had to turn the adjustment screw all the way to one side to bring the socket close enough to the ball joint to reconnect it.

I tried experimenting on a spare set of xenons I had but the stepper motor shaft is pretty much locked in place when no power is applied to it. So I couldn't get the socket close enough to the ball to reconnect. I didn't really try all that hard but just from playing around with it, I can tell you it will be a pain.

Good luck.

Also if you would like pictures of the inside of the housings, I have a few I can post up.
