Did the same, went to go see if I had a trailer brake update due to the recall and found the driver seat module appear. Did that and all is the same, now if I could just find the trailer brake update...
GSM and ABS have not disappeared for me for some time. I am going to give it a go tomorrow at IPMA again. When my Mongoose came tonight I did the CCM and its good. Then I did 2 rounds of GWM and APIM and they are both good. Hopefully we are near the point of BC working!!
Ok so I let it run all night long and I don't know that it worked, also don't know that it did not work. Here is what I show this morning on FDRS: (meaning I can't download or run TCU anymore)
Hopefully now I can actually get an OTA, had the truck since May of 2021 and have yet to receive 1 OTA
