Cheaper option to disable ESS

[billfraley]

I honestly believe that the stop/start cycles are harder on the battery than the starter.

I think it is a good idea to replace the Aux battery with a lithium battery. Lithium batteries will maintain power much better than AGM.

Those small batteries are designed to last a while, it's the larger battery that it hurts the most because it keeps the aux battery charged. Dealership told me that bunches of people bring theirs in thinking it's a aux battery problem and it ends up being a dead cell in the main battery. That was my issue as well and I was convinced it was my Aux battery but once the main battery gets a dead cell it will not charge the Aux battery properly. The main battery will still show good reading voltage wise but on the machine at the dealership it will more than likely show a dead cell. Once I they replaced the main battery I was good to go after 50 miles of driving so the aux battery could charge. The message when off the dash and I haven't had anymore issues. Still got my aux battery installed. I know people still running there aux batteries in their JLs for over 100,000 miles. I'm just saying I have read and talked to people personally at jeep meet ups that have said they replaced the aux battery only to find out they had to replace the main battery also, which probably means it was the main battery the whole time.

My guy at the dealership who I've delt with for about 15yrs and I trust said he hasn't seen 1 come in that had a battery issue that it didn't end up being the main battery when that Auto Start/stop message is on the display.

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

Exactly what I was going to post - the ESS only works on the manual transmission Gladiator when the shifter is in neutral and the clutch pedal has no pressure / is not depressed at all. I’ve found that if I don’t want the engine to shut off, just leaving my foot resting against the clutch pedal is enough to stop the ESS from engaging, even if the shifter is in neutral. It’s not enough to disengage the clutch, just a millimeter or two movement of the pedal.

One topic that seems to be missed is the important role that oil plays as a coolant. At least in high performance engines, the oil carries more heat out of the engine than the real ‘coolant’.

Especially for turbo engines, the prevailing advice has always been to never shut down a hot engine immediately after a hard run, for fear of coking the oil inside the turbo.

For the ecoDiesel, being ‘cooling-challenged’ and being a turbo, it seems appropriate to be concerned with ESS.

I bought the ESS-disable dongle from Amazon, and it seems to work as advertised, and without affecting other functions. It may help others to know that the device has the two eight-pin connectors (male & female), plus a larger third connector that looks like an OBDII connector. The OBDII connector is capped and does not need to be plugged in to anything (it may be a programming port, used only in the factory). The two smaller connectors get installed in-line with a cable into a module that is under the dash, directly above the OBDII port. Therefore it does not get installed behind the push button, so you don’t have to pop off the center of the dash.

I'm the proud owner of a 23 eco diesel that has been in "system not ready, charging" for months, even after multiple trips from Key West to Miami.

So of course I'm interested in a fix before I get stranded.

If your line of thought is that fca, or any car company would not put out a system with known issues, or without properly testing your misguided. They will and do, put out broken crap that they will worry about later.

I bought a 2007.5 Ram in sep of 07 (traded for my Gladdy in 24)

First truck with new 6.7 and dpf (first half of 07 had the 5.9 no dpf).

The dpf showed 80percent full on way from Miami to Key West , called buddy (owner of dealership) he said don't worry, enjoy your weekend bring it back Monday when you leave the Keys.

On way back, stalled multiple times due to clogged dpf and it died in the dealership driveway (pretty funny watching 7 mechanics struggle to push a brand new doorstop into the shop).

My friend told me they were programmed incorrectly from the factory, had to get three different reprogram in the first month I owned it.

Shipped and sold with known incorrect programming.

And don't get me started on the EGR putting soot back into the turbo.

Manufacturers can and will put out crap to meet EPA guidelines or a sales quota or whatever despite how unsmart it seems to us.

Short story they will put out an ess that unduly stresses batteries, starters and internal engine components (due to low oil pressure) to meet some EPA wishlist and leave us to wait on repairs.

Also if they tested the starter/charging/ battery to last x long with ess on, I might get x+y years more with it turned off due to less cycles. That's a win for me.

Awesome story. Changed my life!

The free options usually result in a error light or message. All you have to do is disconnect the Aux Battery Negative cable. ESS will never activate since the Aux Battery will never pass the startup test. However, you will have the constant red A error symbol on the dash.

Let us know how it works. A lot of those no name super cheap devices on Amazon that are similar from China seem to be a mixed bag with intermittent operation.

From the size and price - I wonder if that isn't based off the timer circuit someone posted on youtube a few years ago - once you started the Jeep, it started a countdown, and after x seconds, sent the "I pressed the button" signal.
The parts to make the thing as listed in the video I can no longer find, came up to about 20-25 bucks. If all done in China for the mass market, you know it would be a small fraction of that.

There are other override devices available.
This is the least expensive one I've seen.
And it comes with a handy reusable upholstery tool
not that we need one
for the Gladiator under dash panel.
It's sold by Walmart. Not on Amazon.

Probably easier to meet Walmart's rules for listing on their site than Amazon's.
"sold by" or just listed on the Walmart site (which has become another Amazon for sellers from China)
What does the "sold by" part say?
