When you disconnected the aux negative and the fuse it should have cleared the alert off your dash. If it didn’t then just disconnect all the negative posts from the battery and separate them for a few minutes replace the main negative battery terminal while keeping the aux negative isolated and ensure your fuse is removed and it will clear your codes from your dash.
I have a 2019 Jeep Grand Cherokee, it also has the Stop/Start feature, I thought I could get used to it, but then I realized its just wearing down the starter, the battery and maybe a few other things. Which would mean more repair work down the road. Not happening! Luckily for me, there is a single wire connected to the battery that controls the Start/Stop, I disconnected it and taped it out of the way. Now all I get is the warning light "A!", letting me know its not working, I can live with that. And after almost 3 years of driving like this it hasn't affected any other components.
I'm in East Tn just below Knoxville and my wife and I took flowers up to her family graveyard near the Ky line. I'm driving a 2018 JL with a 4 cyl turbo and automatic. To make things short- guess what happened when I tried to start it up. No Key just a fob. Just click with nothing. You know they routine well. After waiting for almost 2 hrs for my roadside assistance to get me a rollback, he hauled us back to our dealer and there we sit. The dealer had their Delivery boy to bring us home. That was Monday and today is Thursday and still nothing. #1 my first Jeep and #2 my last Jeep. Only have 11370 miles on it and that was trips to Kokomo for my Brother-in-law's funeral. Not to this post you made: I love it. Very informative. I'm a Vietnam Vet , Jet Engine Tech and a Street Rodder but this threw me for a loop. Thanks and again with good documentation like this it is like having a Motor Manual in hand again. God Bless.
I'm up here in Canada...Just a couple of days ago, a purchased a brand new JLU Rubicon, in Montreal, and was in the process of driving it home to New Brunswick, (through the state of Maine)...Half way there, on a minor, 2 lane highway, in the middle of Maine, I had to stop due to a railroad crossing signal... In order to save gas, I put the vehicle in park and shut off the engine...It wouldn't re-start, and road-side service wasn't able to help me...I was stuck, blocking my lane, for about 2.5 hours...Luckily, I found the Key FOB solution, on the internet, in which you physically use the Key FOB to push the starter switch/button, and it actually started... Now, my wife wants me to return the vehicle, to get our money back, but I don't think that's possible up here...
There's a company out of West Virginia that sells an Auto Stop Eliminator for about $100. It was the first mod that I did to my 2023 Wrangler Willys. Best money I've ever spent; takes about 10 minutes to install.
@@AStanton1966 quick question. If the battery is still connected, etc. AND the aux battery ends up dying, doesnt the problem (draining the main battery when aux battery fails) still exist? Its my understanding that the electrical bypass just remembers the last setting and makes it so you dont have to keep turing it off when activated. Thanks for any clarification.
@@JimKonugres I don't know anything about the aux battery on the Wrangler. I wouldn't mess with any main electrical components on my Jeep. If the battery ever croaked, I would go to the dealer to replace it. The battery is under the fuse box in the engine bay and I wouldn't mess with that. All I know is, that I hate that start/stop system on any vehicle. And the Auto Eliminator took care of that!
Stop-start does not really impact fuel mileage, it is all about emissions. The aux battery only powers accessories when engine is stopped by stop-start feature. Can be safely deleted, but dealer has certain FCA obligations. My dealer shop was like "yeah no big deal," but others may be more critical. They just saw it as a "safe" mod. Just ask next time you're at yours.
I have a 2021 JLU sport 2.0L. I disconnected the wiring harness on ESS under the hood. The prong on the right. There is small wiring harness on the battery too. The "light" comes on but I put electrical tape over it.
eTourque..it's the only way. You still have ESS but no stupid Auxillary (motorcycle) battery. During Stop/Stop you have an electric 48V hybrid battery.
At some point pull the small battery, tape up the ends, pull your negative cable, clear the code and you should be good. Had the same issue with my 19, but it didn't strand me.
I just had my Aux battery replaced because my Stop/Start light started coming on. BUT, the light is still on. I can auto start my Jeep, but the auto stop doesn't work. How do you get the light to go off?
The batteries are in parallel. Removing the aux is fine as it’s an assist battery only. Auto start stop is horrible. Bypass. Not worth it. The aux battery will kill the main battery over time as a parasitic draw. Which is why it killed the main battery
Man… why all the irrelevant chat?? People watching this are probably stranded like you were and have to listen to the whole thing. Great initiative, but GET TO THE POINT!!!!

pull the fuse, light will go away.

Sounds like Your remote / key fob battery is dead.

Yup! Bought a similar product after making this video. Easy install and gives you peace of mind.
@@BryanHectic And throws no codes or violates the warranty.

Awesome infor thank you. IF you have to go to the dealer restore everything back to OEM specs.

Wow, I just hope you have filled your coolant reservoir because it looks like it’s empty and that’s more important than your batteries at this point😮

Carry a jump pack should get you home!

Can u please help me

You can jump the battery if you tie it into the posts you need to cross connect the metal posts. Litebrite did a good video on it
Lots a a $500+ To replace that small battery
