ESS removed from MY20 JLUR UK edition?

[JohnnyB]

Hello Ladies & Gents,

Just an update on my MY20 Rubicon!

What with man-flu and work, I've not accrued many miles yet (350) and its nearly been a month since taking ownership of it - excuses, excuses I know!
I'm still 'over the moon' with my purchase, although the one thing that I haven't been able to figure out up and 'til now is the Electronic Start/Stop system? To cut a long story short, there is no menu option for the ESS on the dashboard cluster, and I haven't seen it work at all, even though there is an enable/disable button that illuminates when pressed! I contacted my dealership about two weeks ago regarding this matter and have just received an email stating that according to Jeep Technical' and a Master Tech, they believe that it has been dropped from the options on the vehicle. I know a lot of people stateside would be grateful of this, and if their experiences are anything to go by, I might be too! Just thought I'd share this with the forum, particularly UK customers waiting for a MY20! If anyone does know any different, then please feel free to correct me.

PS I can't seem to stop buying accessories from Quadratec now!!
Cheers

As far as I'm aware there was never a menu option for the start stop system.
The only way of disabling is physically using the button or using a programmer.
Mine works every time I drive even in the really cold temps we've had the past couple of days so not sure why you've never experienced it?

UK Overland btw!

Strange! Option wouldn’t be dropped yet leave the button.

mine took a few miles to start working, decent trips and now it’s fine

Thanks for the information! I suppose it could be that I've just not done a long enough trip yet for it to kick in? I thought it strange to keep the button if the option had been removed.

Thanks for the reply.

This is my first jeep, so only going by the user manual regarding the menu option! It might be that I've not covered enough miles yet, so will get driving and see what happens!
Cheers

I doubt the ESS has been dropped. It’s more likely that there isn’t enough charge in your auxiliary battery due to your relatively low mileage. In these circumstances the ESS won’t operate.

The auxiliary batteries have been known to fail and one of the indicators is the ESS failing to function...if this happens the ESS light is permanently displayed on the dash and at start up you get a message saying ‘service stop/start’ or something similar. I presume you’re not seeing these?

When I scroll through the console screens on my sport, one of the screens shows ESS status and what, if anything, is preventing ESS from functioning. "heating vehicle", "charging battery", etc.

Evening,

Thanks for the information. I'm not seeing anything relating to ESS(lights, messages etc). The only message that I've occasionally seen on the dash is 'AUX switches not available - battery charging'? I'm going to give it a good run out on Saturday and see if that kicks it into life!
Cheers

Hello, I do not seem to have that option on my Rubicon. According to the user manual the ESS menu option should be the one after 'Trip info' but mine isn't there? A few forum members have mentioned that it might be due to my low mileage and the AUX battery not having enough charge, so a drive out will be on the cards Saturday!
Cheers

Yes I suspect the other ’battery charging’ message is confirming our suspicions so hopefully a bit of use will bring the ESS back to life and all will be good. Let us know how you get on.

If your cluster behaves anything like the sport, you may have to enable the ESS page as one of your favorites in the screen setup menu.

what engine do you have? 2.0L Turbo petrol, 3.6L petrol or 3.0L diesel?

I’ve had a quick look at the screen setup options but I can’t see anything relating to ESS? I’ll have another look in the morning just in case ‘I can’t see for looking’ so to speak!
Cheers again.

I have the 2.0L Turbo petrol engine. It’s quite possible that it just hasn’t been used enough to charge the AUX battery. Quite a few members have suggested this as a possible cause so I’ll get some more miles on it and report back!
Cheers for the reply

I am skeptical that a low charge on the auxillary battery would cause the ESS page to not display in the center dash cluster.

and cheers to you too!

I always wanted to say that but, in the states, people look at you a little funny when you do

edit: I just checked my users manual (the 600+ page manual), while some of the menus in the instrument cluster can be hidden (I didn't know that), the Stop/Start menu is not one of them. the manual also states the "StopStart" menu is only shown "if equipped".
