Angry nobus

Just when I thought the coil was the problem. Up pops the nobus.
I'm going to troubleshoot the sensors, ASD and so on that I'm only just now learning about. I need to get some good manual or references for my van. (2003 Ram Van 3500 5.9L) so I can find these sensors and so on.

Big question: I had my windshield replaces about 4 or 5 months ago and I recently realized it is leaking on the inside at the top of the window. A few times I've had small puddles on the driver's side floor mat directly under the dash. As I removed the engine cover, I noticed the underfloor matt was damp. Latter I pulled it back on the drivers side and the wires under were quite wet. It rained yesterday. Could this cause strange electrical problems like shorting the CAN bus to ground?

Now I have a nobus error, and the gauges, inlcuding fuel don't move when the key is on.

I am searching the other nobus threads. If this is so common, it would be great to have a sticky.

No buss generally means the PCM has failed. 9 times out of 10 or better just replacing the PCM repairs this problem.
