U codes are problems on the CAN - controller area network serial data bus. You check if there is a bad module or a wiring problem or not.

No, was hoping for some solution from you guys
This must be some water integration to a plug - I saw this after I cleaned the car ! I took the car in to my workshop and had it inside for a week to see if the moisture would evaporate. Still the same problem.
thanks for your reply

Hi,

I have the same kind of problem with the CAN bus on my JLUR 2.0L.
The gateway is in red like yours and several modules are faulty.

The problem appeared when updating the option code following the replacement of the steering box with the new model and the addition of the hardtop harness.

My Jeep has been stuck at the dealership for two months now.
They replaced two faulty modules without any improvement.
They no longer know what to do and tell me that it is undoubtedly the bypass gateway of my Superchips FLashcal box that caused the update to fail.

What is strange is that when we reconnect the gateway bypass, there are fewer errors but the steering pump cuts off as soon as we turn the steering wheel.
And when we put it back as it was original, there are a lot of errors and the automatic gearbox doesn't work at all.

Have you found a solution to your problem?
I hope your solution will help me solve my problem.

I admit I forgot to unmarry it and reconnect the cables to the firewall as it left the factory.
