I have the EFI tuner on the way for the dpf delete codes and the egr but the others I HAVE NO CLUE ABOUT!!!!!

I need to reflash the comp to the stock settings from the flashpak to the EFI tuner but is it safe to do so ? I am at a total loss here?>


I did the EGR delete from Sinister diesel and all these problems arrised I cleaned the corrosion of the terminals the same day the altinater passed the load test and so did the batteries.... im at a loss

 

I would start looking at your grounding circuit. Check the connections to the body, engine, and frame to see if something is loose.
That is a lot of codes to pop up at one time.

 

^ +1. No grease on the grounds AT ALL.

 

DID U EVER FIGURE THIS PROBLEM OUT? I HAVE THE SAME ORDEAL BUT GAS ENGINE SAME CODES AFTER REPLACING MY PLUGS WILL NOT PASS EMMISIONINS c2202
C2202) Original VIN Mismatch /MISSING / U0141) LOST COMM With BODY CTRL MOD A / U0100) LOST COMM With ECM/PCM A

 

also interesting!

 

I know this thread is old. However load testing a battery may or may not tell you battery is good or bad. Example. My truck 2012 ram 6.7. Truck dead after sitting 2 days. Both batteries load tested good. Went up North. 30deg that night, next day dead. My point is OEM batteries that are over 4 yrs old are on borrowed time. Sounds like new batteries could solve this issue.
