VIDEO : GREMLINS GONE on our Gladiator

[wayoflife]

About time.,, congrats on finding the wiring issue. They are not fun to find

Not gonna lie, I was starting to have my doubts that I would ever find and fix it LOL

Man I’m glad you got it sorted out it stays that way. Crazy how the smallest things can set electrical wild. Also, it’s looks like you have more spare parts than you should .

Thanks! Fortunately, the Jeep still drove fine, it just sucked to drive it. I think it'll hold out and if it doesn't, I have other ideas as to what I can do to make the fix absolute.

Congrats on solving it. Can only imagine the frustration.
Had a diff electrical issue on my JL back in Aug, took it too the dealer after trying most of the things you did.
They kept it almost 3 weeks, trying all kinds of stuff before they solved it. But a few days before they had some corporate Jeep person explain to me that if they can’t solve it, we can discuss a trade in and they would keep my old jeep to scavenge parts.
In the end it was a bent pin on the gateway where the taser connects.
Seem like the simpler things have a bigger impact on all these new electrical/computer systems in the newer jeeps.

Damn, that’s crazy. Glad you got that figured out too.

Thank you and glad to hear your dealership was able to get the problem you were having fixed!

Without question, the big problem with these newer Jeeps is all the CAN BUS and monitoring systems. One loose connection can still provide power to something but a bump in the road or otherwise can cause a brief voltage drop and that will cause the system to throw codes, reboot or worse. One thing I didn't mention in the video but probably should have is that there are multiple plugs along the main harness and that connect the whole thing together. Once I started narrowing things down to the passenger side tail light, I started to disconnect the plugs one at a time in that area and went for a test drive. When unplugged, everything from that point back didn't work but it also didn't trip up the system with a voltage drop. That helped me to determine exactly where/what length of harness I needed to start taking apart and look for the problem.

Great troubleshooting step!

Hopefully all your electrical issues are resolved. Just a thought...consider replacing the self-tapping bolt with a welded stud on the frame. That way, you can secure the ground wires more reliably with a lock nut.

So far so good. I've been testing things for a few weeks before making this video to make sure things are good. As far as the ground goes, the original mounts on the cross member were welded studs. I'm not so sure I want to weld anything in this location due to it being right next to the gas tank and fuel lines but if the problem comes back, I may be forced to do it.

CAN bus itself is good and has been in heavy use since the mid-90s. It seems that the Wrangler/Gladiator only use one physical bus for a whole lot of stuff and the software/firmware in the various interfacing modules is poorly implemented and produces ghosts. Using multiple physical buses with discreet functionality would be more expensive but it would prevent unrelated things from wreaking havoc. If the ground on a module keeps coming and going then the CAN bus would not be very reliable.

what an ordeal! Never would have thought wires from all the way back there could cause all that up front there.

Crazy, right? If it weren't for all the computer monitoring, I don't think something way back there could affect something on the dash.

The electrical gremlins we had on our Jeep Gladiator are finally gone! In this video, you'll get to see and hear about all thing things I tried to get it fixed, what ultimately did the trick and all the things that didn't. Also, if you're a fan of Ripley, be sure to stick around for a short clip of her as well.

Now, if you missed our previous video, some of the problems we were seeing included things like the center stack buttons blinking on and off and not working, error codes popping up on the EVIC such as "Passenger Side Turn Signal" being disabled, "Blindspot Alert Unavailable Service Required" and "Auto Start Stop Disabled". Also, the Infotainment System was having issue as well with it being not functional or constantly rebooting and our climate controls would not work. When the Satellite Radio was on, it would cut in and out and we'd have no controls over volume but could hear the subwoofer making a pulsating popping sound. Of course, you can watch all of this by clicking on the following link.

Thanks, I constantly get the. Blind spot unavailable.

Holy cow that was a long process of chasing the problem down. Glad you finally found it and fixed the issue.

 

[Lperdue]

Happy you was able to get it sorted out. I didn’t realize the JT was down for that long.

Using multiple physical buses with discreet functionality would be more expensive but it would prevent unrelated things from wreaking havoc.

The JLs and Gladiators have a couple of buses actually. There's the main bus which is called CAN C, another is the Internal High Speed bus. In addition, some modules do use Private buses to talk each other direct, such as the shifter for example. It talks to the trans through the main bus and a private bus simultaneously. There is also Lin Bus but its usually for small things like steering wheel controls, compass, the aux switches, etc.
