Engine replaced on Freightliner Cascadia no communication with truck....

Hello I posted this issue in the general repair chat but i am thinking it might be freightliner specific.

Replaced the Cummins ISX 15 engine No. 79830729 with a rebuilt Cummins ISX 15 No.79940637 epa16 model. Engine runs but i get no instrument readout in dash and display shows No engine and No ABS. I am wondering if i need to change something with the CPC4 to get it to recognize the engine. I don't know what exactly the CPC4 does so i am just guessing. Anyone hit this issue when replacing an engine? Also cannot access the engine thru the duech connector in truck.

 

Ok does anyone know of any decent mechanic knowledgeable about these type of wiring issues in or around Boise Idaho…. I really need someone who is knowledgeable about this issue.
