Kenworth T680 CAN communication issues

I am having issues with mine, every time I would get the truck wet underneath I have issues with the check engine light coming on, now I have have the same thing that’s being described in this forum, j1939 and can bus communications issues.

 

Don’t know if this applies to your truck.
I had a Detroit DD15. An over zealous truck wash attendant pressure washed the engine and water got in the connector on the ECM.
Fortunately I found it soon enough before the pins got corroded.

 

We’re is that located can you text me a pick of you still have it
