Having trouble coding the headlamp ECU and the actuation module for the right headlight. Using the autel. I got to the point of needing to scan a qr code off the old module and can't finish because I can't get it to scan because of corrosion on the code. Now in the process I have also lost the left led marker light. Any advice would be great

You must scan the qr code on top of the headlight.

Still working with this one. The qr code on the headlight assembly was the correct one. But apparently when body shop installed the old modules on new headlight it knocked the led element out in the new light. Body shop has a new one on the way. Insurance company not very happy.
