I have a 2020 Ram 3.6L Big Horn Edition 4x4 Crew and my Electronic Stability, 4-wheel drive and check engine light are all on. The error code that I get is U0403-00 Implausible Data Received From T-Case. The truck runs fine, it still goes into 4-wheel drive. I cleared all the codes and when I restarted the truck all of the warning lights re-appeared. What can I check and/or do I need to take it to a dealer?
