I recently acquired a 2013 T&C touring. I was pulling codes to troubleshoot my cooling fan. It just turned out to be an unseated plug. However I also got a P0685 code as well. I haven't had any no start or shutdown issues that you would expect to accompany that code. I popped in a new relay since I had one laying around but I still keep coming up with that code. Any thoughts would be greatly appreciated.
