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

 

loosen/tighten, clean the big screw down plug in the power box beside the battery

 

Ok ill try that thx

 

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!

 

Thanks for letting us know the fix.
