FIXED Jeep Gladiator - Auto Stop/Start (ESS) Warning Light After re-gear

Getting the Autostop/start (ESS) warning light, backup camera and backup lights failing after re-gearing. This is apparently a common problem with manual transmission Wranglers and Gladiators. Setting the gears in Tazer to 5.13 gears didn't help. Was going to take to the dealer but found the answer on Jeep Gladiator forum. Check it out! Please like and subscribe. #JTRSPARTACUS

Just regeared to 4.88 on 2022 MT Willys Sport Gladiator - same issue as outlined here. Really appreciate the video and info, will be doing this today. The shop that did the regear didn't know about this either.

[@JTRSpartacus]

Glad this was useful. Be sure to completely disconnect both batteries and I turned on the headlights to completely discharge the system. Good luck 🍀 #JTRSPARTACUS

[@mynameisphunk]

@@JTRSpartacus did your Gladiator experience jerky acceleration, esp at sub-2k rpm light throttle, for the 500-1000 miles after resetting things? I've seen other forum posts about this and mine is doing it. No other lights etc. Just 3700 miles on mine now.

@@mynameisphunk not that I particularly noticed. Maybe the computer is confused 🫤.

[@rickster2929]

Same here exactly what happened after re-gearing. I took it back they fixed it (dealership). They told me me it was a update but I'm sure they just reboot the system like you did here. 😁👍

[@JTRSpartacus]

Glad they got it right! Thanks for watching ! #JTRSPARTACUS

[@michaelandchiyospaulding2689]

Thanks man, this helped. Changed the tires before and just did full reboots of the system, a couple sleep cycles, and the relearn process of 60 in 6th and never had an issue. This time I could not get rid of that darn light without disconnecting the battery.

I have a '21 that I took the 2nd day of owning to lift and new tires/wheels. This light has been on for 2 years 😄 Decided I'd try to handle it since I'm due for inspection. I never thought the lift was the problem, good grief. I have an auto, hopefully this will still fix mine!

[@JTRSpartacus]

Good luck!

[@tumbes2000]

I had a similar issue but it was the open hood sensor. Apparently it's on the same circuit as the autostart and it was causing the autostart to mess up. Dealer replace the sensor and everything is back to normal.

[@alands6111]

I have a 2020 grand cherokee overland. Bought it last week and the stop/start warning keeps popping up. It's an automatic transmission so I can't really do what you did here in the video. Anyone know how I can fix it?, I live in a developing country and there's no jeep dealership and service area near me so I have to fix it myself. Any suggestions on what I should do?

[@JTRSpartacus]

Could be tie auxiliary battery. After you check all your connections , Check your second battery with a voltage meter. If it’s dead it will eventually kill your main battery. Good luck #JTRSPARTACUS

[@LarryRichelli]

I have a 2021 Wrangler Rubicon with a manual having this same problem. I sure wish you could have gone through the fix as you it because you didn't post the procedure as you said you would so I am still in the dark. I have googled it and gone through forum posts and cannot figure out how to fix this.

[@JTRSpartacus]

Go to 3:19. That’s the printed procedure I used. Might need to do it a couple times for it to work properly. Here is a Jeep Gladiator forum post about this. Good luck www.jeepgladiatorforum.com/forum/threads/p08a6-and-auto-stop-start-failure.26921/#post-808033 #JTRSPARTACUS

Wheres the video of the process , like the full video i cant find it :S My AC is off im dying cause of the heat haha, can you please share here the link for the video of what you did once you disconected the negative side of the battery? THANKS!!!!!!!

[@JTRSpartacus]

Sorry. No video. If you disconnect all of the negative side cables it will disconnect from the main battery and sux battery.

[@scottsimmons8946]

This is great, thanks a ton. I've been having the same issue since May. What exactly did you disconnect? I understand the negative connection on the battery, but what was the 2nd connection you disconnected? It wasn't so clear in the video. Also, what was your re-learning process like? Just driving in 6th gear between 40 and 80 MPH? Did you give any thought to the accelerator pedal position or the flywheel torque? Both of those are listed in the procedure, but how are those positions determined? Thanks again!

[@JTRSpartacus]

There is a second black wire on the negative terminal. It’s attached to the wire near the battery terminal. It goes to the auxiliary battery underneath. The easiest way to tell is to disconnect and see if it turns on or starts. If it doesn’t turn on or start it’s disconnected. The relearn is Pretty much just driving in 6th depressing the accelerator for 20 seconds. I posted the pic of the procedure in my community post section so it’s easier to see. Check it out. Good luck! #JTRSPARTACUS

[@scottsimmons8946]

@@JTRSpartacus It worked!!! Thanks a ton for posting this. Jeep told me I was on my own and a Tazer didn't work so I had given up hope. But I just disconnected both cables from the negative terminal, then disconnected those two cables from each other, let it sit for five minutes and boom... start/stop worked again. It was working right out of the driveway. Usually it errors out once I hit 4th gear, but on my way to the highway for the relearning process, it never errored out. Still did the highway drive in 6th for good measure. Thanks again! I'll spread the word and direct people to your video.

Experiencing same issues on my JTR-MT after regear to 5.13. Had same issue before after putting 37's on and dealer fixed it then (i believe with this solution) but they didn't mention this when i called them on the road after regear. Instruction pdf is beyond my tech expertise but i tried to follow instructions on your channel. Didn't work for me, couple ideas why: (1) I disconnected the negative terminal clamp and both black wires connected to it--however i did not disconnect those black wires from each other as the connections were very tight and i didn't want to damage wires--perhaps i could with better tools (i seem to recall you mentioning need to disconnect wires from each other--does that have something to do with disconnecting both batteries?? pdf mentions need to disconnect both and i have no idea how to disconnect auxiliary battery. I tapped brake pedal a little like you suggested but wasn't sure how long i had to do that for. (2) My DTC P08A6 problems appear at irregular, unpredictable intervals from start and this particular time, as i left on my way to highway for "6th gear learnin'" it happened almost immediately as i left my driveway. In any event, if i disconnect battery at home it is unlikely i would make it to highway before problem appears. Is it necessary to do the 6th gear learning prior to error appearing? Not sure that is possible.

[@JTRSpartacus]

You definitely need to disconnect the auxiliary battery - all of the cables. If you have power to anything, the relearn procedure won’t work. You may need to get creative about how /where you disconnect and reconnect - close to a highway. It’s a pain but it’ll work. Good luck ! #JTRSPARTACUS

[@lawnews]

@@JTRSpartacus i see, so apparently the relearn must be completed before error happens--that will indeed be challenging--thanks!

[@JTRSpartacus]

@@lawnews I think that it must be completed before the error pops up. Good luck.

20 Mojave not a manual but my jeep kept losing charge so after about 3 days of jumpstarting it I bought a new battery still has the warning on thinking it might be the alternator 😢

Have you read the code? Does the dash ga😅ge show lower than 13 volts. Also You can take a voltage reading while running Could be a lot of things. Good luck. #JTRSPARTACUS

[@michaelbradley8997]

Hey I had the same problem after lifting mine. I didn't re gear it though. Got it back from dealer who said it was fixed and it died at a red light. It did this twice. After second time a light came on saying find a safe place to pull off road engine will cut off. I thought yeah right. It did and it lost all power after several attempts trying to start it.

[@JTRSpartacus]

Sorry to hear. Sounds a bit different but hopefully you can get it straightened out.

[@irvgotti94]

I just had this issue. Replace the Aux battery and also look at the fuse link next to the fuse box under the hood. Check with continuity port 3 on the large fuse link. I had to replace mine

[@Mojave-iv1dm]

I just did a gear swap to 5.13s and I'm having the same issue. I reset all ecu's with jscan but when I start it up after the reset the autostop light comes on within seconds. How am I supposed to do the relearn procedure when the light comes on almost instantly?

The only way I found was to completely disconnect the batteries. Resetting with a taser (same principle) didn’t work for me. Good luck.

I am having trouble with mine, it seems like it’s stuck in neutral no matter what gear I try to switch it too and won’t move

[@JTRSpartacus]

That seems like a different issue. Needs some trouble shooting. Could be transfer case not engaged fully engaged in a gear or linkage broken and stuck in neutral, broken linkage in the gear shifter assembly or another issue. Very hard to tell. Will it roll freely when it appears to be in gear? Will it start? If you put it in 4wd low and start it does anything change? Does it give you any errors or codes? Good luck! #JTRSPARTACUS

@@JTRSpartacus it starts fine, no check engine light or anything like that. I can shift to any gear and it feels tight, so the clutch feels fine.

I googled a lot and found it. The dealer had no clue. There is also a lot more of good info on Jeep Gladiator Forum too. www.jeepgladiatorforum.com/ You’ll need to determine the underlying cause of the start stop light - there are a ton of posts on this in the forum but common problems include: dead battery (ies - usually the auxiliary battery), hood closed plunger/connection, loose fuses/breakers, bad ESS module.
