I have a 2010 renegade with a fairly new battery and it is giving me code P1656 and will not start. I have read it is DESS line shorted to ground. I have read every forum I could find on it and fixes include replacing battery, replacing ignition switch or replacing ECU. I will load test the battery tomorrow but has anyone had this issue and found the problem. There is not much info on it, but it seems to be a common problem.
