Hi Mitch what was the problem witjn B1792 and B1793 codes with truck Im having same issueI re-added the trailer brake controller and the performance/off road pages and it all works again. I did see that the negative gain button on the trailer brake switch on the dash was stuck pushed in before I re enabled it so that may have been an issue too but unsure. As of now, it was a pinched/corroded wire along the frame rail, and possibly a stuck button or maybe a bad value in alfaobd but my issue has been resolved. Thanks to all for the helpful input!
