This is the procedure from the ESM for the '12 M. It doesn't say so, but many times the procedure won't take if you don't begin it in the full closed position:
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1. Press the tilt up switch and start the tilt up operation.
2. Release the tilt up switch once, press the tilt up switch again, press and hold the switch until lid pops up.
3. The glass lid moves slight toward tilt up direction then stop. (Press and hold the switch during this operation)
4. Release the switch again, and press the tilt up switch within the first 4 seconds. (Press and hold the
switch)
5. After 4 seconds, the glass lid will be automatically operated in sequence of tilt down, slide open and slide
close.
6. After the glass lid stops, release the switch 0.5 second later. (Press and hold the switch during this operation)
7. If slide switch operates normally, this initialization is done.
If it tries to move but won't, chances are the mechanism is jammed and it isn't a timing or electrical problem. If it isn't moving or making any noises when you press the switch, chances are it's a motor or harness issue. On M's the motor gets its power from the BCM, so there isn't really any separate fuse to check. At the motor connector, you should see ignition power on the beige wire, battery power on yellow, and a good ground on black.
