    Hey everyone. I am in need of help. I have a 2012 Coronado that will not start.I washed it the other day and went to start it. Nothing. the boss and I managed to pull start it and get it to our shop. now it wont even pull start. The truck gives networking error codes and wont even try to start. when I turn the key I hear a relay click and that is it. I tried starting the truck by shorting the starter and it turns the engine but that is it. there are 2 network codes on the dash I have to pull them and Will post them here as well. any ideas anyone?

    you said you washed the truck. did you put pressure water on motor's ecm or nearby ? I think communication is lost between motors ecm (mcm) and aftertreatment's modul (acm) . now check the connectors on mcm and acm. acm is located behind of left front wheel's splash guard.

    He used the auto wash. We had the def delete done on it a few months ago and the acm is supposed to be disabled

    j1939 datalink test must be done by using diagnosticlink 8. that software will show you where is the fault. now check one more place for shortened/grounded wires. behind the sleeper, that cable for qualcom antenna. that cable has j1939 wires.
