I just got the error message

“Stop/Start Unavailable
Service
Stop/Start
System”

If I remember correctly, this indicates the auxiliary battery is going bad again. I replaced it in 2022 and have a tazer mini. The start stop has been disabled since 2021. Is the auxiliary battery dead again after 4 years? Even with the start stop disabled?

This is a 2021 JLUR with the 2.0
