Default ECM, no bus.

I have been driving my truck and had problems with it going down to idle and no pedal response and it will come back. I have since installed the following, apps, vp44, and map sensor. The problem still exists though previous problems were fixed by doing all that. I was told my ecm may be going. I have found when the problem happens if I disconnect the batteries it goes away for awhile. I have also noticed a lack of power at times as well. I am now getting No Bus in my odometer and I am finding codes p1698, p0382, p1693 and p1694. Glow plug circuit, no transmission bus message, no engine bus message, and companion module. I have also found my rpm needle bounces while in park and the other night my rpm needle went to zero and it sounded like the engine bogged down a bit. I don't know if these problems are linked or my ECM or PCM are shot. I am flustered and would much appreciate some feedback. Thanks.
