Hello!
I am currently 500 miles into a roadtrip and am having my auto stop start and traction control issues. Today was about 300 miles out on and around 5 hours of total drive time. At first blind spot went out (this sometimes happen, mostly when I am on the trail or on the beach, but not a huge deal). Later today had my auto stop start and traction control service light come on and it’s not the first time. I first had it happened with auto stop start and traction control issue after off roading the Tillamook FireBreak 5 and Cedar Tree on June 1. It also did on the same day on way back home (around 90 mins). Then again when I was doing some off-roading by my home with some friend July 3. Then again today (July 25). After restarting the Jeep, it goes away. I have had a code reader this time and last time. Unfortunately the code reader this time couldn’t detect it, but I think it’s an issue with the cheap Amazon one I purchased, so planning on returning (app is rated poor so that’s why I don’t trust it anymore). I going to include the codes I got last time (July 3) since I imagine they are the same.

PCM: P258B (active), C0501 (pending), C0507 (pending), C050D (pending), and C0513 (pending).
EPS: C212A-16 (stored).
SGW: B22A9-49 (pending).
HVAC: B11CB-92 (stored), B1058-92 (stored), and B1058-12 (stored)
ABS: C1252-92 (active)

Has anyone else ran into this? Is it a simple fix or something I have to take it to shop for? Any thing I should test? I brought all my tools, so I can definitely work on it and would like to do before I head into a no service zone. Thank you!

How's your battery voltage on main and aux when you separate them?

I’ll have to check them, that’s what I was kinda thinking maybe the voltage is getting low. Combine, I randomly would monitor them and it would sit a bit low at 13V (combine, driving on highway).

I separated my aux battery when I started getting the aux switches unavailable message. I just run off the main battery and have ESS disabled. There could be a common ground point that links to all those codes as well that may be loose or corroded. I would start with the the batteries first. Test them separately.

So I just tested them at AutoZone, both test good and charge was good. I had them both tested separately. What else should I try?
