Default No bus code

Hey all, new ram just threw a code, no bus. CEL, abs and air bag lights are all on and there is no guages. Been searching around and have seen it could be the crank position sensor, a loose wire or ground, or a bad connection somewhere. What's the best place to start and what should I be looking for ? Anyone have this before? Thanks

Disconnect the battery before you clean that big plug, and clean/check the PCM connectors also while the battery is disconnected;.

Fixed it, seems to have been a bad ground on the pcm. Checked fuses first, all were good, disconnected battry, tightened the power box screw to no avail, cleaned pcm ground and that seemed to do it!
