Initialization/Teach Procedure For a New Drive Assembly:

"Teach" refers to the sunroof system's learning a baseline profile for the system. This is almost always done following an initialization.

  1. Press and hold the CLOSE switch (Do NOT use 'express' close) until the sunroof moves slightly past full vent (2mm) and suddenly back to Full Vent
  2. Quickly release the CLOSE switch and re-press and hold it (within 1.0 second) while the sunroof moves to Full Open and back to Closed (the roof should start to move within about 4 seconds).
  3. Release the switch and verify successful initialization by performing One-Touch Open and Close operations.
