Hey guys, Have an issue with my 2006 LJ. Mil lamp is on so when I got to work this morning tried to pull codes and found that the scan tool could not communicate with the PCM.

Under Instrument Cluster I did have this message. "pcm/single board engine controller message not received".

If one of you guys out there can point me in a direction I would be extremely happy.
