Press and hold the open switch for 10 seconds or more. The glass panel will move further rearward of the open position, stall at the hard stop, and move back slightly to the soft stop or full-open position.
In your vid, you released the switch after the hard-stop/soft-stop movement. Gotta hold it more than 10 seconds, even if the glass has finished it's deal. Releasing it early is essentially telling the controller to abort the cal. :yes:

Any luck?

GMspeak is hard to translate into English sometimes. These sunroof instructions would be much easier to decipher if they'd left out the part about the panel movement and just said 'Press and hold the open switch for more than 10 seconds.' eSI is chock full of little quirks like this, where it only really makes sense after you've seen how a procedure works in the real world.

It also doesn't help that there are two separate but slightly different calibration procedures, one for a new motor/module and another one for reinstalling the original.
