@brewtus98Well now I created my own problem by testing this "feature". The ESS not available/warning will not go away now. I've started/stopped the Jeep about a dozen times and still there. Maybe coincidentally the aux battery died when I tried this?
You can use a code reader/SGW bypass to clear the code. You can try a total 12v power kill as that might also clear the code..
I mentioned load testing each battery as your 2018's batteries are aging out. IF, you have dealer do a load test ask them to keep/show you each paper printout.... a printout for each battery. This way you know they actually did the load tests..
Here is how a way total 12v power kill on the JL.
