I had this same problem with my Wrangler JLU. The dealership "tried" to fix it 3 different times by replacing the aux battery to no effect. After much research, I found a post on the wranglerjl forums where someone mentioned the Power Distribution Block on there's was loose. Had the dealership check the block on mine and some connections were loose. After tightening, I never had the issue again. I did read that some people had the block replaced. I hope this helps!My new to me 21 JTRD always has this message on. Today I replaced the Aux battery and still see the message even after a short test drive. During the drive I did notice the voltage fluctuating between 12 and 14 volts. Once I got home I used my volt meter to test the original aux battery since it was now out of the Jeep and it was reading about 12.3 volts. I also tested the main battery with the engine off and it was also reading 12.3 volts. Unfortunately I did not test the new aux battery before installing it but it had a date code of 12/22 so I'm sure it was fine.
What other options do I have to resolve this issue?
