Hey all... I recently replaced the battery on my 2019 Laramie with 53K miles. After replacing the battery all is well and starts fine with no CEL lights on the dash. As I live in an area that requires an every-other-year emissions e-check I stopped into the self test kiosk and the scanner reported that it couldn't communicate with my ECU. The full service bay reported the same problem. Returning home my scan tools reports the same code P1DF3. I called the dealers service department and the service advisor asked if I had changed the battery recently. When I acknowledged I had he said that the ECU would inititate but might take 800-1000 miles. Does this sound right?? I've never heard of this before.
