2018 JLUR nightmare

[mbrose1994]

Not exactly the video I wanted to share, but this one tell you where to push to release the tabs.

Yes, was quite helpful.
So, SUCCESS! Maybe there is some errand discussion in this thread, but #5 by ErAcEr was spot on as I could verify the part and gave clue to price.
After replacing old star connector, all is GOOD! "No CAN bus" message gone, everything working as designed.
Thanks all!

My vote is the CANBUS. I had the same thing happen and replacing the CANBUS cured it. The CANBUS is where all of those sensors come together. Make sure to get a MOPAR part. Amazon has cheap Chinese knock offs that I wouldn't trust. It's an easy part to change, located behind the glove box. There are plenty of youtube videos showing how.

It's recommended if you change 1 battery to change them both at the same time. You can also disconnect the aux battery neg cable at the main battery and pull fuse 42 to take the aux battery out of the ESS system. Lots of people on the forum have done that and if you search for it there are many threads discussing it.

My wife has a 2018 JL that had the Christmas tree dashboard problem. We had it towed to a dealer three times with no success except a nice bill. They told us on the final one that it was an anti-lock brake controller, costing $1,000 plus installation, with the added bonus of a 10-month wait for the part. We got the vehicle running and drove it home with the check engine light on. I found this forum and we started with a battery change ourselves. That did not do it. I ordered the Can Bus connector for less than $100, and since I am a quadriplegic my wife installed it with the help of the YouTube video we found. The installation took about 20 minutes. The lights have all gone out, the jeep has been running fine for about 10 trips now. As an added bonus in now turns off and on at stop lights which was a feature that did not work through all of this. Thank you for your recommendation!

Welcome to the forum, glad that fixed it for you! I can't take any credit though as it's a fix that I learned on this forum from the many members who are way smarter than me. I simply shared my experience of following recommendations made by those smart people. This forum has lots of great members that are willing to share their knowledge, I've learned a lot from them and appreciate their time and experience. Stick around on here and you will learn so much about your Jeep, and see all kinds of mods that will empty your bank account.
