Dash lights flashing all kinds of faults then quit, had to erase/clear engine fault DISC what does this mean and what is the fix?

There is a green can bus star connector behind the glove box door that seems to get cracked solder joints and cause multiple issues. Not 100% sure that will be your problem, but I would start there.

Thank you, this is exactly what mine is doing, once it would not let me put it in gear.

This video at the 7 minute mark shows one of these CAN BUS Star connectors taken apart and shows the cracked solder joints. I would imagine these probably could get reflowed with a soldering iron to save on a replacement connector if one has the skill set for it.

Interesting stuff here! I had a lit up dash today, wipers, blower, stability, ABS, check engine on my 2020 gladiator sport. It did start up normally after about 20 mins, leaving only the check engine. I didn't get as many deactivations as in the video, but some overlap.

My main batt is from 10/22 and not sure on the aux batt yet, but I'm leaning toward that being the issue first.

What do you think? This all started a few mornings ago after a huge rain storm overnight, i was just thinking it agitated maybe some corrosion on that aux batt?

Thank you. I replaced this today, after yesterday being dead in 1 lane traffic jam (I made it worse) when JT went into auto park after every light lit up. I've been chasing the gremlin that lights up my dash, hoping this can bus is the cure for $94 and 10min fix.

Update, 6 weeks since replacement, and NO problems. Must've been my fix. Thank you
