New Mexico, it ain't "new" & it ain't "mexico"
After sitting for 2-days went to start, and briefly saw a message about "low battery threshold", truck wouldn't start and also heard a 'pop' sounding from amplifier. Dash lit up with messages. Threw a reader on it and getting 19 codes, 11 of them are U303 - "Battery Voltage Circuit Voltage Below Threshold" on different modules. Others are on Powertrain Control, all terrain control, audio, etc. (photos attached)

Battery is 6-months old (replaced OEM) and charging now, may also try a jump afterwards if still won't turn-over.

And thoughts, suggestions.....

All sounds like a low voltage issue. Once it’s all charged up check to see if a door or light was left open/on. My bet is once charged up it’ll run without a fault.

Sorry to hear of your troubles. I had the same exact thing happen on mine. All the low voltage codes and it was the battery.

Could also be a bad connection at the battery. Check the terminals. The only true way to test a battery is to put a load on it. Any autozone ect type place will do it free for you.

I’m switching over to a new battery in a month. X2 Power.
