Cheaper option to disable ESS

[Blade1668]

I respect your personal choice. ?

I mean, one would think the starter and other components were engineered to maintain a specific duty cycle. But, logic should follow that the life will be extended by lowering the number of cycles. This will not always ring true, but based on averages it should.

I have read about Aux battery failures, and speculation that it may have been caused by not using ESS. I don’t really buy it though.

Battery technology is not that complicated. If a battery is marginal, and the system stops charging it correctly, it will likely lead to an early demise. In the case of our Jeeps, there is some additional complexity due to the way the vehicle senses voltage and adapts charging accordingly. Then you have dealer service techs who don’t understand the system, or how to troubleshoot it. It’s like a doctor diagnosing cancer without knowing how to determine the cause.

I am not sure I would make the jump to say ESS is causing engine failures. It would seem that it is just a variable, and that the failure would have happened anyway. Also, just because something is part of the symptom, doesn’t mean it is part of the root cause. There are a lot of variables that would need to be examined.

If we look at it with anecdotal evidence we can draw bad conclusions. My first engine failure ever, in a low mileage scenario, was also my first vehicle that had an ESS system. Anecdotally, ESS leads to premature engine failure. This is the problem with anecdotal evidence.

I work with a lot of engineers, yes some of them lack common sense, but most of them are capable of troubleshooting what they understand.

My wild ass assumption on engine problems was on the cam shaft lob failure being possible due to intermittent oil less starts. I've seen some abused, high mileage / hours engines with less wear than has been seen with the 3.6s that have failed. It could be a factor in the problem not the root reason. Higher temperatures added with thinner oil engine starting then stop, start, stop, each time oil pressure drops off then needs to re pressurized and be forced to bearings surfaces. I've seen firearms to include machine guns have wear on surfaces, galling and failure due to lack of lubrication in the past. In that area it was due to jackasses listening to other jackasses telling them to use substandard lubrication or none at all so dirt, dust and sand wouldn't stick plus easier to clean. I know my example isn't the same but lack of lubrication is the same"???". A engine is cycling a lot more than any normal machinegun does in just one hour of operation let alone 3000 miles.

My comment on engineers is a wide brush stroke some is tongue in cheek but I've met quite a few that are idiots that lack of "uncommon" sense.

On the ESS battery failures I think it's been hashed out quite well and probably due to combination of things. Lack of being fully charged, recharged, bad batch of them, under charging, ect ect.
I've been lucky on the battery problem but I have been proactive with my JT charging system and have a solar system charging the batteries too. On my few stops at dealership for anything I even informed service department that I would probably need to point out the additional complexity to it.

not the smartest way but since I almost never buckle my seat belt im not worried with ESS ... but again... definitely not the smartest or safest move.

I don't understand why there is so much drama with this. OP found a solution he liked and wanted to share. If you don't like the solution don't buy it. I thought it was good information. Whether I buy one or not.

Exactly, this post was just to inform others about a product I found on Amazon. The approval of others is not needed. I have already made the decision to buy and install it.

It’s just like anything online or in social media. Some people have to impose their opinions on others. It would be different if someone is posting in a way that they are trying to coerce others. Otherwise, just scroll past what you don’t like. It really is that simple.

 

[TomH]

Yes, why?

 

[FitfulGoat]

Yes, why?

There is more context to the comments in here the more you spend on this forum. The fact of the matter is that any thread on ESS is now a joke due to the sheer volume and hate for the function. Nothing directed at the OP outside of him touching on a subject that elicits the aforementioned comments.

That and it’s the Internet... People are dicks in real life and even more so when you remove any repercussions and add a screen and keyboard. ?

I ordered one, I have a 21 with a manual transmission. Will note how it goes.

It would be nice if Jscan could be setup to simply remember the ESS button setting when you shut the vehicle off. So if you've toggled the button off and kill the vehicle , the ECU remembers this setting and applies it automatically on the next start cycle. I can do this with Bimmercode on my Supra.

JScan is just toggling features for the most part. Adding a monitor for the button is not in the BCM code. The add-on device is providing this monitor via a tiny chipset.

That would be turning it into a device with 'live' functions, just like the Tazer. JScan only works with changeable options that exist in the truck computer.

I agreed. The OP didn't came out like he discovered something new. It's an option that's cheaper than my Smartstopstart unit that i paid $125.

Manual transmission, the even cheaper solution, don't shift Into neutral when you stop and you never have to worry about ESS.

This sounds like a decent solution a lot of the time. But this also means you have to keep the clutch pedal depressed.

I wish I had a manual trans, but I would still likely want to have an automated solution.

That's not the issue all the time. It's also been well documented on here that people who routinely don't use the ESS like it's supposed to be used or try to delete it have battery issues. Read to many threads on it on here and most of the time the person says something along the lines of deleting or not using the ESS. I guess since your a engineer you know better than me or FCA, I think they might be looking for strong motivated Engineers as well.

If the ESS doesn't cut the engine off, the alternator powers the systems in the Jeep. Also, the starter lives a much easier life.

Reading through this, maybe the 50th thread I have read regarding the Stop/Start systems, I wonder if anybody has tried to disable the stop/start via the brake sensor. Ah sh!t, I've got to study now.
