This is a code for a internal problem in the power train control module (PCM) It is saying there is no communication. Make sure there is a good connection at the module and the wiring is good. If no problems there then the PCM will need to be replaced.

Make sure you disconnect the battery first.
Make sure the connectors on the PCM/ECM are tight. When removed look for spread terminals, burnt spots, corrosion, etc. Anything that will cause a bad connection
