I have a list of codes that I need to understand. Engine is not running right and trans is crazy. Any help would be appreciated.code listECMp0380 - intake air heater relay#1p1698 - no Transmission bus messagesp0341 - cmp signal errorPCMp1492 - Batt. temp. sensor voltage too high= not plugged in but is it needed?p0463 - fuel sender unit volts too highp1694 - no engine bus messages receivedp1687 - no mic bus messages receivedp1693 - mil fault in companion modulep1594 - charging system voltage too highp1899 - park/neutral switch failurep1682 - charging system voltage too lowwhat do I need to do to make the pcm and ecm talk to each other?Its not in a dodge truck by the way. Im also using a Chevy alternator.What specific codes will effect the engine?Thanks in advanceRon

With that many different codes, you might try regrounding the engine and transmission. Also, clean the battery posts, looking for corrosion.Others will chime in.

Here is the article about the CCD network. http://articles.mopar1973man.com/general-cummins/34-engine-system/81-ccd-data-bus All the codes have a link going to the diagnostics of each one and explains what and how to fix.
