Initialization/Teach Procedure:

WARNING: This page is about a different car, the 2018 Cadillac XT5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The sunshade motor must be calibrated before the sunroof motor.
If the Initialization/Teach Process fails, disconnect the battery to reset the sunroof and sunshade motors. Wait 1 minute before reconnecting the battery.
If the switch is held for more than 10 seconds after the glass or sunshade has completed its teach/learn cycle, the sunroof can throw a 'stuck switch' fault code. If this happens repeat the 2 steps above.
The Control Module provides obstacle blockage detection. If the Initialization/Teach Process is not carried out completely, the sunshade may stop and reverse slightly when it gets to the location where it needs to push down the windscreen.
If multiple failed Initialization/Teach Process failures occur, remove the control module and operate the Sunshade by hand to verify there is no blockage.

Step 1 - Fully close the sunshade by holding down the close switch. Once in the closed position, release the switch. Now press the switch again and continue to hold. The sunshade will go through a teach/learn cycle and begin to move. Continue to hold the switch until the sunshade returns to a fully closed position.

Step 2 - Fully close the sunroof glass by holding down the close switch. Once in the closed position, release the switch. Now press the switch again and continue to hold. The glass will go through a teach/learn cycle and begin to move. Continue to hold the switch until the glass returns to a fully closed position.
