Does it have a passenger a/c heater control on the roof?
Major bus error
Need help. Husband is tech savvy and this has him frustrated. Got in one morning and all lights on dash lit and bus error. He has taken this van apart and replaced the tcim and then disconnected one module at a time. 4 days later no idea where or what is causing this and havent been able to narrow it down.

Need to check it with a scanner to see what codes it's throwing. Needs to be a scanner capable of reading all systems. If you don't have access to one, you can get AlfaOBD and a Veepeak OBD adapter and have that capability for under $100.
Pay special attention to codes that start with a U. They will throw in any system. Make note of what system you read each code in. If multiple systems report a communication error to a single component, that is likely the source of your issue. Check the wiring to that component before replacing it. Try cleaning the contacts and see if that resolves the problem.
If that doesn't get you going, come back and tell us what codes you found and where from. I can get diagrams and procedures to help you if I know what area you need to look at. Oh, and although they are pretty similar, the year (and engine if 08-10) would be helpful info.

What is the age and condition of the battery? Are the connections clean and tight? Chrysler control modules do not tolerate low voltage conditions and all sorts of weird and random stuff happens.

Open it and unplug it to see if anything changes.
No codes in ANY system? Check all your ground connections.

5th Generation Engine Bay Grounding Points
Does anyone have a diagram of where all the grounding points in the engine bay are? I have an odd P0622 code that popped up and the battery and alternator are testing fine. I'm planning on cleaning the electrical connections / battery posts and grounding points. Thanks

Can you update us on the outcome so we can better understand what is happening please.
We have resolved the problem. No easy feat. My husband had to trace wires after he tested every module. When a wire shirted out and he foubd that wire and there were 2 modules he didnt know about in rear under van and it was the rear sensor one. He was able to disconnect. He is getting part but van is driveable. He took apart the van inside. Its crazy. But i think the dash gave us a clue we didnt understand. Even though i left the van in park when we turned it on the r for reverse was on the dash as well as no bus. Amazing noone else has had this issue. My husband has watched like all you tube videos. My son who is also extremely smart..98 on asvap and is an electrician ..came over and helped. They now know just how smart my van is lol. Since he has a similar van he now knows the wiring and modules. It would be better if chrysler gave a diagram as they kept finding modules. My husband said if he had taken to mechanic they would have wanted to replace the whole wiring harness and that wouodnt have fixed the problem. Can you imagine what this would have cost someone who had to pay a mechanic. My husband spent 4 days on this. I think there beeds to be a recall or at least a info page on their site that informs people. Oh and since tye rear tailgate wouldnt open he had to search and find how to open by taking panel off. He wasnt impressed there wasnt an easier way
Yep my van was same way
