Transmission Fault Peterbilt 579 2024. I have a 2017 peterbilt 579 with a transmission fault. Is the transmission not going into gear?

Where is the ecm fuse located on 2010 peterbilt 386 and should i disconnect it or something to reset? I have a 2020 peterbilt 579 with the awful collision mitigation system and i have a question regarding the hookup for tweaking the settings or hopefully disabling the whole idiotic thing all together.
