Default 2012 RAM 2500HD - NO BUS message all warning lights on

I am in Austin TX, I have a 2012 Dodge RAM 2500 HD Deisel with about 4000 miles on it. I just went to start the truck this morning all the warning lights in the dash are on, the wipers will not turn off, the radio will not turn on it has a NO BUS meesage on the dash. The truck does start and does seem, to drive though I have not taken it out on the road yet. Any ideas what is going on. We had a lot of rain and thunder last night/this morning

Computer issue, take it in. Could be as simple as a loose connection or as bad as needing a new one.

With that said you are more bold that I am. If warning lights are on I am not going to drive it.

There was another guy on this forum with issues similar to yours ( his was a 1500). His problems were caused by water getting in to the inside of the door when he had his windows tinted. So with all the rain, is it possible some module got wet?

Sounds like TIPM issue to me, but what do i know. My brother just went thru this, replaced TIPM, problem gone.
Pedro Dog has a good memory...lol, i forgot about the other guy on here with the watered down door.

I'm sure it's in the shop by now but a reflash by disconecting the battery would have been a good idea to start looking.

Thanks LU, and let's not forget Mikey, his similar problems were caused by the Multi-Function Switch. Seems like any module in these truck that uses the CAN Bus can and screws with the Bus, can cause weird TIPM related failures.

To all, thanks for your input. I did take it into the dealer yesterday, I am yet to hear what they have found, I should know this morning. So what was strange on Sunday after the SUN came out I let it stand for a few hours I went back to the truck to try it again. This time everything seemed to work but the engine check light came on. I will keep you all posted on the final outcome.
