Replaced the Aux battery and now ESS works again!

[HEMI_HOGG]

On my 2021 Jeep Gladiator my ESS stopped working shortly after purchasing the Jeep in January- Today- with the help of my awesome wife, went under the wheel well to access the aux. battery- had my main battery checked as well and that is still good- followed the steps on the internet and happy to say it worked out. Went with a Duralast Platinum aux battery.
When I showed up at the auto store, they knew right away it was a Jeep with that two battery setup.

Congratulations!
There's an easier no-cost method, but you got it!
