Anyone using the Ford VCM-II unit? I updated mine to IDS 117.01 and it works on my 2018 F150, but I cannot get it to work on the 2020 F250. I keep receiving a Testman error 12 12 266146. Searched all over and can't find any information about this error, hoping someone has some input.

Did you get it to work? I’m looking to get IDS and VCM II. Any suggestions?
