Bit of a delay in getting back to this. I updated the Stage 1 map to the newer version that has the fix for the ASS. (I didnt actually realize that you had to update the map itself after a FW update on the AP until I read that on the Cobb site at the weekend).

Since update, i see all of the ASS info on the dash now as expected, but the truck still doesn't actually stop. It now always states that it is on due to charging. I am wondering if there is something else at play here or if there is some parameter change re voltage that means it is never reached.

I put the battery on charge over night on a battery tender and the ASS worked as expected. Looks like my battery is struggling to maintain enough charge during these winter months...
