Hi there. The code that kind of indicates the root source of your problem is the P1603 - which is a Chrysler specific OBD-II trouble code that indicates PCM internal dual - port RM communication failure. This code typically occurs when the PCM has not be correctly reprogrammed by a dealer. Before you attempt any repairs or continue trying to trace your issue, I would recommend having this done or starting from scratch and purchasing a replacement PCM or have a professional mechanic come to your location to complete an electrical inspection to determine if it’s an open circuit issue.
