Software: ISTA
1.)After you replace the LED board, launch ISTA and head over to the "tree chart".
2.)Find "LEM" and click on display faults (bottom right corner).
3.)Find your fault (in my case, "lighting of the tweeter, front right..." and click on calculate test plan.
4.)Select ambient lighting LEM and continue
5.)From here once again select your fault and continue.
6.)The next couple steps just asks you questions such as, are the connectors secure, is there voltage, etc....
7.) Assuming you don't have an electrical issue and it is just a faulty led board, proceed to the autocorrect test. Once performed, it will "activate" the led light and start to work once again.
8.) Exit ISTA and drink beer.

Amazing post, thank you!
I’m going to change mine soon, but not sure where to go to find someone with ISTA. Do most BMW mechanics (non-dealership) have ISTA? Thanks again!
