Hi - I'm new here... I decided to follow a writeup to get OTA Sync updates working again using FDRS with a 2 day license with hopes of resolving the issue where wireless Carplay stopped working. Ford Support said OTA updates haven't been happening on my truck and that was the issue. Upon following the writeup to get OTA updates manually installed, and diving into FDRS as instructed, I noticed several other SW updates were available and I decided to run them. After doing this and seeing what appeared to be successful installation, I reran the Network Test and now both the BCM and TRM are throwing BTC's shown in the images attached. I am very new to this and do not understand what could be going on here but these errors did not appear to exist prior to the updates performed. I'm looking for some general guidance here to avoid going to the dealer who is asking a $300 diag fee before additional charges for update procedures. I'd love to learn to solve these problems myself when possible... Thanks in advance.
Edit: the B1305 was my dumb mistake of leaving the hood popped open while running the test
