I have seen a lot of No Bus discussion on this site but nothing that seems to help me figure this one out!
I have changed the catalytic converter and went thru several 02 sensors on bank 2 sensor 2. The light stays off for a while, but comes back on with the same code. I finally tried a Snap-on Modis and it would not communicate. Upon further checking, I can see the No Bus in the mileage window. Mopar mechanic even tried to hook up via wireless with no joy. I have a friend who is a Mopar mechanic try to find the issue at the ODB connection under the dash with a test light. He didn't have time to trace things out and left me with some wiring diagrams. I didn't really understand how to do this and haven't touched it since. He seemed to think there is more than 1 bus involved and I need to figure out which one it is. I'm not sure how to trace these diagrams down, but I do have a parts Liberty available. Will this be solved if I swap the PCM's?
Any suggestions would be appreciated!
