I am in the process of restoring a 2014 renegade 1K that spend a week under water.(I got a really good deal on it!!) The first time I hooked a battery up to it without turning on the key or run switch the display read something like "transmission failure". So I took the battery off and disconnected all the electrical connections and let everything dry out. Now when I hook a battery up I get nothing. I have checked the main fuses and found power in a few places. I think the ECM is fried. Is there any way to check it? Do I have to swap out the display and key when swapping ECM? :th_smiliefrustrated
