Driver Information Display/Cluster Electronics Won't Shut Off

Short summary: got my 2016 Jeep Grand Cherokee in May, only has around 2300 miles on it. Got fed up with it doing hard down shifts, I do a lot of city driving and it's terrible. Very jerky, can feel and hear it, especially when it goes from 2nd to 1st gear.

So I took it into the dealer, they did a software update/flash which they said addresses the very issue I was experiencing. Well, guess what, it didn't do anything. Still very bad shifting. Seems like a failing or defective transmission. I'll be pressing on this issue with the dealer more next week, but they introduced a new problem that is more urgent to solve now:

Ever since I got it back from the dealer, the computer in the instrument cluster (Driver Information Display "DID") and lights around the media hub (USB ports, etc.) will NOT shut off when the vehicle is off. This is draining my battery, I can tell because the ESS function is not working, and tells me it is disabled due to the battery charging when I look at the ESS info in the DID.

Anyone know how I can fix this? Would bring it into the dealer, but naturally they are closed on Saturdays and it's a long weekend. Don't want to wake up to a dead battery, also not good for overall battery life. I'm thinking I need to play with the fuses or possibly do a reset from the Uconnect? But not sure if the Uconnect system is tied to the DID system, so I don't want to reset Uconnect if all it's going to do is erase all my radio and power settings, etc.

Very disappointed in my new JGC and service dealer. Any help would be appreciated.

Re: Driver Information Display/Cluster Electronics Won't Shut Off

Because it is usually a computer issue, and cars don't come with "Alt", "Ctrl", "Del" keys, the three fingered salute is out.


The replacement is to disconnect a battery cable for 15 minutes or so.

Re: Driver Information Display/Cluster Electronics Won't Shut Off

Well, I never excelled in auto shop and don't want to take a chance and screw something up by unplugging a battery wire. Also difficult to get to under the passenger seat and probably don't have the right tools.

So I decided to figure out which fuses are tied to the interior components that won't turn off, pull the fuses so at least my battery isn't draining and the lights aren't being overworked or burning out by being on 24/7, and then wait until Tuesday to put the fuses back in and take it into the dealer and let them figure it out the mess.

There were 4 fuses that needed to be pulled in case anyone should find themselves in this predicament:

F84 - 15 blue (Instrument cluster panel)
F51 - 15 blue (ignition button)
F67 - 15 blue (aux & USB port panel)
F94 - 10 red (shifter lights and 4wd switch)

I would agree with Bill, remove the battery cable and let everything reset. pulling fuses you might get lucky but you may also induce other issues. your jeep has a dozen or so modules (think of them as little computers) for various systems that are always chattering with each other to keep things running smooth, having modules flashed or pulling fuses to them interrupt the happy harmony they have with themselves and each other. Usually they just pick back up and all is fine but some times not. pulling the battery cable takes all the modules down and lets them all come backup gracefully as they were designed. No guarantee but often this can fix strange electrical gremlins, random or induced by flashes. also often dealer don't think to do this for troubleshooting for whatever reason.

Certainly don't do anything you are uncomfortable with but pulling the negative battery cable is not hard. move passenger seat all the way forward, from the back seat pop the floor cover up and use a 10mm wrench to remove the negative battery cable leave it off for a period of time. I do it before I go to bed then put back on in morning but 15 min 30 min should also be fine too the point is don't just put it back on immediately give it time to bleed off any residual. there have been three times over the last three years that this has fixed issues for me. also maybe it will help that trans issue, crazy 3.5 years later they still got shift issues with that transmission on the new ones rolling off the line. I'm assuming you have the v6 as that's been the problem prone trans.
