With ISTA+ there are separate functions for "Repair" and "Transfer Box (VTG) Calibrate". AFAIK, "Repair" is when you're replacing the transfer box or major components, while "Calibrate" is when changed fluid or other minor repairs. I only performed the "Calibrate" and didn't have to clear any errors.

Just realized, since this is a diff fluid change thread, we should have made these posts in the "DIY: Let's change our transfer case fluid" thread.
