Aux battery bypass not working

[AskBin]

I have a Tazer as well. Let me know.

after a 50km drive in today, autostop/start claims "autostop/start disabled, untill battery is charged" or something along those lines. looks to be properly disabled and not just turned off with the push button.

ill check and see if my charging system is functioning normally also and my alternatos not being commanded to overcharge my battery (im assuming its is a variable charging system on the diesel)

But to answer your question, yes it seems to be disabled, tazor button push memory still functions like normal, and still no reported codes/faults. if yourespecially worried i believe thats something that can be software disabled with jscan, i dont have a way of getting a license and testing that myself lmao so YMMV

My 2019 wrangler Rubicon 3.6 started doing this thing where it won't crank the first time I push the button, the next time it will crank just fine. But tells me to service electronic stop/start. And it also threw a check engine light. But overall drove just fine with zero issues.

My aux battery was reading low on my meter so I just went and replaced it. Bought a brand new battery. Got it installed and now I get a battery icon on the dash and ess disabled light. And after running for a bit I get a message for "vehicle will turn off soon please come to a safe stop". Before changing the battery I could at least drive it.

I've looked around the forum, and tried to disable the aux battery by pulling fuse 42 and unplugging the aux negative from the main. But when the aux negative is pulled off, my jeep has no power at all. So I can't even attempt to start the jeep to see if that fixed it.

Tutorial after tutorial my jeep should work the same as all the others I've seen and read, except I have no power.

Can anyone help me? sorry if this is the wrong thread.

My thought here is that your main battery is on its way to battery heaven. If you want to retain the AUX batetry and keep the circuit stock it is wise to simply replace both batteries at the same time. I have had zero success just replacing the AUX, even if for a short time the warning light goes out. It always comes back on and then the main has to be replaced. It's why I started doing the bypass on our tour JTs, we were just wasting money, time & effort on the AUX batteries.
