Changed both batteries now cameras don’t work

[Factoid]

2020 Rubicon w/6.4L hemi. I started getting the telltale signs of an aux battery failure (aux switches not available, gear indicator not lit, etc), so I changed both batteries this morning. Everything works properly except the two cameras. I tried the reset (press both volume and tune buttons for 10-20 seconds) and that didn’t do anything. Thoughts and ideas?

Give it 24 hours and a few cycles. They should come back.

I believe the system can take a bit to reset itself. Like up to 24 hours. Had this issue when I changed mine a while back. Next day, all was good. Hope yours is the same

Yes, the Uconnect system can take up to 24 hours to recover from a system reboot (full power loss).

Give it a few hours like the others have said - and if that doesn't work, my first question is how did you access the aux battery? The easy through the fender way, or through the top, removing PDC and fuse panel?

 

[Factoid]

I think the easy way is through the PDC from the top. I can do it in less than an hour and I have aux switches, lights and a heavy duty winch. Jacking, removing the tire, removing the fender liner (breaking clips), and then removing the battery seems more difficult.

FWIW, when I replaced mine through the fender liner, I:
1) Didn’t have to jack it up
2) Didn’t have to remove the tire; just cranked it full driver
3) Admittedly broke plastic rivets but didn’t realize that it could be done without breaking clips (remove the ones that are designed to be removable, 3 or 4 of them I think, and the liner is slotted where the non-removable style rivets are)
4) and either way requires removing the battery.

Took maybe 30 minutes and I would say is ultimately less “risky” than dealing with the fuse box removal/replacement.

I’m not trying to start a war of words as I haven’t performed the replacement from the top and so I have no comparison; but I will say that it sure seems like going through the fender would be the easier approach.

Yeah, more than one person has shown videos of how it can be done without removing all the stuff people assumed had to be removed.
I prefer less risk. That's me. And I have other stuff wired up there - power steps, winch, snow plow and other accessories that would make it more time consuming going through the top.

i was just asking because there's been multiple people who have gone through the top and then had things not work. So I asked- how was the process done - just in case a 24 hour wait doesn't return things to normal. Any time you remove electrical connections, stuff can happen. That's all I was saying.
If the wait doesn't fix it.........
but it likely will in any case.
(besides, with health and age, my days of leaning over high fenders are dwindling in number. I'd rather sit.)

My cameras are back! Thank you all.

As a follow up on technique, either works. If I was not replacing both batteries, I probably would go through the fender liner. Once the main battery is out of the way and all my accessories wired to the battery held at bay with bungees, it was easy. There really should be no electrical issues. The four connectors snap into the aux battery cover, the fuse box then snaps into place, and the four bolts ensure everything is aligned properly. Just work the four bolts in steps and you are good to go. By the way, my 2019 corvette uses this same design (thank god there is no aux battery) but you have to remove the fuse box to change a couple spark plugs on that side. No issues.

Finally, there is no bending. With 37’s and the Mopar lift, it is the perfect height for easy work with no bending over.

Need to change my batteries and readig this has me curious. There is a bypass for the auxiliary battery. If I put a jumper in place can I keep the system live while switching batteries 1 a a time. Do the auxiliary thru fender the jumper t and replace main?

If I end up replacing batteries out of warranty in the future - that's my plan. Keep the system alive either via a jump pack or, one battery at a time, using a jumper to keep the electronics alive while swapping things out.

Other older vehicles can be kept alive while swapping batteries by using a feed into the cigarette lighter (which is alive all the time on older vehicles)
And jump packs sometimes say "can be used to keep electronics powered while changing batteries".
It's a lot more risky - one wrong move and sparks fly, but I've worked with hot circuits for years and you just be very careful, attention to detail, cover or wrap anything that shouldn't touch anything else.

Anyway, that's my plan for the future - keep it alive, one battery at a time.

The two cameras were the only short-term casualties but they came back as some predicted in 24 hours. Everything else - garage door openers, preferences, etc. stayed. I don’t use radio presets, so they may have been lost. Since I retired, I cancelled a bunch of nickel and dime charges that added up to almost $500/month! Sirius radio, some streaming services, LinkedIn premium, etc. I kept Amazon radio and use it for music in all my vehicles.

Good luck with the change! One step at a time and there is a good YouTube tutorial if you need it.

I laugh when I see those commercials on TV that say they track your subscriptions and cancel all of the unused or unwanted subscriptions for you - and as if it's dozens.
I told my wife- if I get to the point I have no clue what I'm subscribed to, or it reaches that level of dozens - get power of attorney over my finances!
Seriously, people are to the point that they need an app to track all of their subscriptions and then need to rely on an app to cancel and do it for you and do it right?
Wow.

Thank goodness garage door opener settings stay put - that's the hardest thing out of all things to set up on these. I almost see a lift kit as being easier than setting up a garage door opener on these - based on their instructions which actually used to contain a loop - you had to read beginning to end and then go back to the middle to make it work.

The subscription crap is a slow drip to poverty if you’re not careful. Fortunately, we put all on PayPal. That allowed us to see them all in one place and PayPal includes a link to the Unsubscribe function for each. Thank goodness for that as I think these companies try to make it as difficult as possible to unsubscribe. I agree on the garage door opener…whew!

Good to see some outfits are now including a simple "click to unsubscribe" link - and knowing PP, they would totally block any charges after you click that. Some companies keep charging even after the command to stop..... hoping if they can get by with one here, a couple over there, it all adds up and most won't fight it.
