Permanently disable engine auto start stop (ESS) at stoplights?

[MikeJenkins]

What about just pressing the button after you start the car? Mine is a habit now kind of like putting on a seatbelt

Figure somebody here could start a business here. Buy a programmer and charge a fee for mailing it out and user paying return postage. I might be a player if somebody did it.

I don't think that would work. You need to leave it plugged into the port on the Jeep for it to continue doing it's job. Also, you have to "marry" the device to the Jeep in question and it appears that when you "unmarry" it, it goes back to the previous factory setting. Whether this is required or they just did it intentionally to keep someone from doing what you suggest, I don't know...

It would have been nice if the kiddie engineers would have made it a discrete switch that you could set and leave it in that condition. Instead, they made things with momentary contact switches that the vehicle's computer is constantly polling. If it realizes that a switch has been pressed and released, it updates it's internal memory and changes the state for whatever is controlled by that switch. Just more whiz-bang stuff by a bunch of kiddie engineers that should be just designing video games and not anything that might have life and death consequences if they screw up.

I'm an engineer, I've had to work with these kids and I am not impressed with them...

Now, get off my lawn, dammit!

Since the auto-off button has an LED associated with it, that gives me an idea.

It would be possible to fairly easily build a device that monitored that LED and if it detected the light not lit, momentarily close the connection that the switch normally activates, thus causing the car's computer to think that you pressed the button. Probably about $5 in parts and a fairly short bit of Arduino coding to get it done.

Just slide the shifter into "M" mode when coming to a stop. You can leave it there until you start out or shift back to drive - ESS will stay off for that idle cycle. I find this very useful since ESS functions when I don't mind it and it is easily turned off when I don't want it to function.

Doesn't the flash method, rather than permanently disable it, just, by default, turn it off when the rig starts..in other words flip the default to ESS off?

"Nothing for nothing" but you could turn it on again after a flashed rig's been reconfigured on this attribute and the engine started, by pressing the button right?

I just checked with Jeep Informant on YouTube and he says that the Tazer JL just changes the initial state of the auto stop start system. If you manually press the auto stop start button again, the state will be toggled.

He also said that there was not a fuse that could be pulled to disable the auto start stop.

If the auto stop start button is anything like the starter button and the rear of it can accessed as easily, I can think of an easy solution that would cost maybe $5-6. It would involve a small Arduino micro-controller, a relay, and possibly an optional toggle switch.

Here's a write-up that I've done for a possible design for such a system. Pretty simple really...

Unfortunately, doing as you suggest does not work.

Towed a Uhaul this weekend and still cut off at lights.

I tried the unplug idea. It does disable the ESS but it also keeps telling me my hood is open and doesn't allow dash display to stay in the mode I set it to. Still hoping to find a solution.

If I find it irritating with the manual transmission, I'll probably implement this:

Just unplug the connector going to the auxiliary battery. Yes the ESS warning light will stay on but that is it. Simple solution and can easily be plugged back on if wanted. This is what we did on our JL.

this guy has one coming out in a couple of weeks, for the JL.

I’m thinking the Taser JL could be better as it does a lot more for not honestly that much more, but will have to see what the pricing is.

One concern might be with all these systems that try to correct perceived deficiencies in the design of the vehicle or to just add features to it is that they see to all rely on using the OBD port. Although there are some splitter cables available for the OBD port, I have to wonder if at some point, it's going to get a bit inconvenient with all that stuff hanging around down there.

We as humans are so Lazy we can't push a button. And you would rather distroy you new vehicle.

How silly people are. VOID YOUR WARRANTY THEN GO AND LIE TO JEEP FOR HELP.
