Start Stop Not Ready - nothing else

[Rusty PW]

My ESS started working again with the warmer weather. Nothing else has changed. But I have to drive about 12 miles before it does.

I just regeared my '23 JTR to 5.13s and I noticed when driving it during the break in period that the Auto Start/Stop button was no longer disengaged, it was no longer lit (I have the Tazer so it always would stay off). I came to a stop and the vehicle did not shut off. I looked in the menu screen and it displayed "Start/Stop Not Ready". No additional error codes. No warning lights on dash lit.
I really dont care if it is not working, as I always had it set to keep the auto start/stop off. But I am concerned this may lead to other issues.
Are there any updates on the cause of this? It appears for some it just goes away after awhile for some reason, and for others it required a replacement of the aux battery. I know I could do an aux delete, but I would really like to find the cause of this issue.

My 23 ecodiesel just spent 4 days in the shop for the "Start/Stop Not Ready" error message. First they changed both batteries no luck. Then they changed the IBS no luck. Scratched their heads, called STAR for help still no luck. Tech noticed soot level at 75%, decided to perform manual regen. After regan all good. Go figure.

UPDATE: So I read somewhere that someone unmarried and remarried their Tazer and everything started working properly again. So after trying everything else (including testing the battery, which showed it still good), I decided it couldnt hurt to try. I unmarried the Tazer. Took it for a short drive. Then came home and remarried the Tazer. And that worked. Start/Stop shows "Ready", no more DTC codes, everything operating as it should. I am not sure why this additional step of unmarrying and remarrying was needed, but it worked.
