Auto Start-Stop Question

[Shabba84]

I find the auto start-stop very annoying. Just wondering if there is any harm in manually turning it off each time I start the engine and running without it on?

I always punch the button to disable the ESS. It’s worthless and I don’t care what they say, it’s not good for the engine to constantly be shutting down and starting up

It does no actual harm to your Jeep. If it doesn't bother you, then don't sweat it, my friend.

Many here hate it because they hate anything that has to do with technology. They would prefer if they could buy a Jeep with a Rubicon suspension and Sport cab - as bare bones as possible.

Others here hate it because they believe that it adds unnecessary wear-and-tear to the engine, constantly starting and stopping all the time. I've yet to see any of them produce actual data proving this, likely because it doesn't exist.

There's value in everyone's opinions and beliefs, though. Same reason I change my oil every 5K miles even though in all reality it's probably fine to go 7.5K or even 10K with the proper filter/oil.

I ran mine with ESS for 2 years with no problems whatsoever. Only recently disabled it with a dongle because my AUX battery died (the battery that runs the ESS system) and it was cheaper to disable it than it was to replace the battery.

Great overview of the entire conversation! Thank you!

Agree and that's on my list of things to do but rather than pulling fuses I'd just as soon remove the aux battery altogether. What issues will that trigger?

The only accessories I wil, or possibly will be adding, are my mobile (not hand-held) dual-band amateur radio transceiver and, possibky, a 12-volt dash cam. The transceiver will be powered directly from the main battery just like the radios in every other vehicle I've owned since the 1970's. The dash cam is something I have very little experience with but it, too, will be powered from the main battery.

Given that is there ANY reason to keep the aux battery?

K.I.S.S.

Rich:

Removing and/or merely disconnecting the Aux battery and pulling Fuse 42 aren't so much mutually exclusive steps as they are ones meant to occur in tandem.

Pulling Fuse 42 and/or fused jumpering of terminals N1 and N2 in the Power Distribution Center force any calls by the vehicle for electrical current from the ESS battery to get rerouted to the main battery. Let me know if you want linked references to this.

Without this Fuse pull or fused jumpering of terminals N1 and N2 in your PDC, your JL, (because it's newer than an early 2018 which would be stranded) will, if you disconnect and/or remove the ESS battery, fail to crank on the first try, but in subsequent attempts to crank, try doing so off of only the main battery.

If successful it will turn the ESS off light on in the dash (that "A" with a near circle around it followed by an exclamation point icon near the "E" in Empty on the fuel gauge). Some might think that a feature, not needing to turn ESS off with the button push or after market products to do so but they guy who taught us all these techniques (@Jebiruph) thinks that we should aim to keep this ESS off light in the dash as its illumination other under circumstances can reveal vehicle problems that it being on all the time might hide.

That ESS off light will remain on until the next cold crank after either a new energized ESS battery is replaced, or Fuse 42 is pulled or a fused jumper is placed between N1 and N2.

Restated, the fused jumper of Fuse 42 pull tricks the vehicle into thinking that calls for electrical current from the main battery are actually coming from the ESS battery.

On top of all of this I'd make sure that the ESS system is switched off. It's probably best not to run it on the JL with just one battery, much as many other vehicle models do ESS with one battery.

As it regards your dual band and dash camera, particularly the latter, if you plan on running it in parking mode with the engine off, make sure it has a voltage cut off feature that's otherwise engage around...I'd say 12.3 volts or higher. We don't want your camera running down the cranking battery.

As it regards your question as to keeping the ESS battery, if you've committed to not running ESS events I'd say there is more advantage in disconnecting and/or removing it that keeping it, as it can cannibalize the main battery. Some keep it within the vehicle but electrically isolated, charging it independently for use in running other accessories or as a backup.

The trace gas carbon dioxide is about .04% of the atmosphere. If it drops below .02% plant life dies. Wake up to the scam.

Ok....trees need CO2. They are big "bank accounts" for it that convert it, with sunlight into tree mass, storing that CO2 until released when the tree dies and decomposes.

So, yes, we need CO2, but are you suggesting that we're battling to keep enough in our atmosphere...really?

You need the CO2 for all plants, fruit trees, vegetables, all of it. We're not in a battle to keep enough, we are in a battle with the people that think this is problem and we can fix it by spending billions, wrecking economies, freezing people to death, etc., etc., etc. It's just a power and money grab.

"The trace gas carbon dioxide is about .04% of the atmosphere. If it drops below .02% plant life dies. Wake up to the scam."


This suggests we need to watch the CO2 levels don't get to low. Even if it's a fact about low CO2 levels and death to photosynthetic organisms that use CO2 as an input to create mass as you point out, it's similar in fact to "if a trolley car runs over me in bed tonight I'll die."

It's not a concern, in fact the opposite, too much CO2 is.

You may have a point about the futility of trying to intervene, much that, no offense intended, I hope you're wrong, for all of our sakes about that, and yes, trying will come at unfair cost and benefit to particular groups of people. If we don't try, well, we all know how that's likely to turn out.

And maybe we're moving too fast, or maybe other factors are contributing to our warming and weather changes. But sunlight is more abundant than oil. We've got to transition before running out of the latter. And people won't transition, at higher cost, unless forced to.

And yes, all these so called green initiatives, like dead batteries in the ground come at the own costs as we seem to fight the more pressing problems by introducing new ones that we can only hope will come to bite us in the ass at an even more distant point in time, when the prior problem is solved.

No harm. That is what the button is for.

To start my Jeep:

Press the start button
Press the auto stop start button
Press the radio power button
Press the fan button
Press the "accept terms" in the info screen.

It makes me feel like I am in a sci fi movie!

The same number of actions it takes to start a 747! ? no kidding.

I was shocked to find that ESS is also present with a manual transmission. It kills the engine when in neutral when the jeep is stopped. As soon as you engage the clutch it fires back up. For some reason this is way more annoying with a manual than an auto.

wonder if that hack will work for me….

Sorry to add one more post on ESS but I have a manual transmission (3.6 L) and I have never had ESS turn the engine off. I'm definitely not complaining but I was curious what state the vehicle needs to be in for it to activate or if it was broken.

I do see a message which states "ESS Ready" but the engine keeps running (fortunately). It might be that I usually leave the vehicle in 1st gear with the clutch engaged at stop lights but I also remember a day when I was waiting for a flagger to give me the go ahead to proceed. I know I had it in neutral and my foot was off the clutch. I was sort of waiting for ESS to kick in. After about 5 minutes of waiting for the flagger to give me the go-ahead, I turned the engine off.

So I'm not sure if my ESS is broken or if I'm not regularly putting it in a state where the brain says to cut the ignition. Anyone else here with a manual transmission and an ESS that doesn't turn the engine off? Thanks

I’ve also read that on manual transmission JLs that the clutch needs to be depressed.

It will activate during a test drive when the customer, who keeps his vehicles for 10+ years and thus wasn't familiar with the voodoo called "ESS", brings the 3-pedal Jeep to a complete stop and then wonders why the damn engine shut off. Ahem.

That may be it. Have a look in the Owner's Manual. The list of conditions that must be present in order to allow an ESS event is longer than we might guess.

I tell my kids that it's the Avenger button incase we ever need to call Iron Man.

Guessing this happened to you? My last new vehicle was a 2017 Honda Accord that came with a real ignition key and no ESS. I remember pulling up alongside other cars with ESS (no idea what it was called at the time) and wondered how they could stand having their car turn off so often. Glad my ESS is broken or at a minimum doesn't like me.

Thanks for the link. That's a heck of a list.

I installed it shortly after buying my Jeep and haven't touched the button since.

If you want to press the button yourself after starting the Jeep, every time, you will do no damage other than wear out the button after a few million cycles.

I would not install the "Auto Stop Eliminator" offering or other such knock, even if you gave it to me for free..

The knockoff offering is known to hiccup on occasion. It will work and then it won't work occasionally.

-> I read where one JT owner had an issue with this unit where it kept UConnect awake when it hiccuped and the guy ended up with a no start situation thanks to battery(s) depletion.

Going with a SmartStopStart unit that is known to never ever hiccup and that does the job every time, year after year is the way to go.

Most forum members that have gone with an offering to deal with just the ESS Button push have gone with the original SmartStopStart.

You can buy the original SmartStopStart unit from forum sponsor @SmartStopStart.com for the same price. Why buy a knockoff that is known to be problematic.
