All Electronic Safety System Service Alerts?

[MattC]

All electronic safety system warnings have activated. Service ABS, electronic stability control, four-wheel-drive system, looks like even the collision alert is out. Anyone seen this? 2019 JLUR

More than likely your aux battery is toast.

If you need to replace the aux battery, replace the main battery at the same time.

I suggest reading this thread on how to replace the main and this for the aux by the awesome @Rhinebeck01

I completely agree with @Obi Wan that batteries in need of replacement need to, at the very least, be ruled in/out as an initial step.

That said, if you are not one to run the ESS system or care about keeping your vehicle in factory wire conditions for say warranty reasons, this may be a good time to replace only the main battery and permanently bypass the ESS battery.

I have no "horse in this race" here except to say, if you're not running ESS events, why spend the money on the second battery?

But that said, if either battery is shot, both should be replaced, or only the main battery, and the ESS battery disconnected. Please don't hook a new main battery up to an old ESS battery.

It is just guessing for anyone to try to diagnose your problems based on the light alone. Pull DTC’s and go from there. If you can’t, this is all arbitrary.

Ironically, I too received the light show on my 2019's dash beginning with Service Electronic Stability control. It got worse from there. I felt like I was about to crash hard (figuratively speaking) as the dash was on a full freak out. The Jeep fluttered with error messages, tones, and warnings including the Service Shifter and many other bad things. It was losing its mind. One warning that does not appear on your dash is when the electronic assist for power steering goes off line. I'll just say it's not fun at all to turn this beast without power steering. I was 5 miles from home and made it there safely. All of this happened at 70 mph in traffic.

I called my dealer and found I had missed the service guys by 2 hours (Saturday hours) but did visit with my sales guy. Let me say a couple things here - my dealer experience through 3 vehicles has been Five Stars. My sales guy and I are good friends as a result. He lives 2 miles from my house and drives a new Rubicon 4xe - he's a Jeep guy. The dealer is coming for the Jeep tomorrow to tow it back for service. I have an extended warranty for just this sort of thing in case the powertrain warranty coughs. I'm at 57K so I should be good.

Here's the "funny" part - I didn't get to speak to my sales guy at first so I left a voice message that told what happened and that I needed his help asap. I totally forgot it was April 1st, which also happens to be my wife's birthday. I thought "crap, he thinks I'm pulling his chain" and may not call me back. Luckily, he took the call seriously and called me back fairly quick. We both had a laugh about it being April Fools Day.

I expect to be without the Jeep for a week but who really knows? If they can fix it and the problems don't resurface then great as until now the Jeep has been superb. Otherwise, I'm prepared for plan B and they do have a couple of Rubicons that would work out well as replacements. Downside is my Jeep is Billet Silver and that color no longer exists. My choices are Sarge Green or White. It's still a big IF that I have to trade off but I'm ready none the less. Fingers crossed that I get the Jeep back soon...oh, one more important fact - this is a 2.0 eTorque that had the main battery replaced 6 months ago by the dealer. No second battery unless you count the 48v eTorque battery. I'm thinking wheel sensor...

We were getting lots of warning lights and even loss of power steering every time we drove the Jeep. Two weeks ago, I replaced the green can-bus connection block behind the glove box. No issues since. The part was $12 on ebay and took about 10 minutes to replace. I'd start there.

Thank you! I had just read the post https://www.jlwranglerforums.com/fo...up-loss-of-steering.75531/page-3#post-2310387 and agree, great place to start! With luck, I'll be driving again tonight if the part is in stock. Should still be covered under warranty. If not, ebay is my friend!

So here's an update...based off of what I learned about the green can-bus connection behind the dash glove box (super easy to get to) I did a bit of wiggling and seating of connections. This allowed me to start and drive the Jeep to the dealer for service this morning. No light show, still had a CEL.

Service tech ran codes and it blew his mind how many were listed. Literally pages of error codes. I showed him the green can-bus connection which he noted and I left it in their hands to resolve. Confirmed that I'm still under warranty, too. I'm anxious to see the outcome and really appreciate this forum!

Is this what you saw on your dash?

 

[Grooster]

Is this what you saw on your dash? (Stop safely, don't die message)

No - never got that. I did get practically everything else. I think I might have been happier to see this rather than the flood of "Danger Danger" messages I got at 70 mph. Wasn't a fan of the engine stumbling during this, either. But it calmed itself and kindly left me without power steering to get home with. Go figure.

Looks like I'll get the Jeep back this afternoon. Two TSBs on the Jeep - one for a wire that had to have the pushpin seated correctly and the other for the green can-bus connection replacement. I'll share the TSB numbers once I have my paperwork.

Wow! You had more than me! All of those except the message that said stop vehicle safely.

It ended up being a bad fuse array and both bad batteries.

Knock on wood I’ve been pretty lucky so far but I did buy the lifetime warranty before they discontinued it and that has saved me way more than the warranty cost so far! Hopefully whatever is found is covered. They already replaced the auxiliary battery once.

Still don't have the Jeep back. Maybe today but I'm not holding my breath. Wife really wants her Cherokee back. Guess I'll be walking soon.
