Just purchased a 2021 ram 1500 Laramie sport in November. Since then had a few cluster lights come on but disappear on their own. Battery was replaced. Since battery replacement codes have still popped up but disappeared on their own. Yesterday hooked up a exterior LED light and threw a bunch of codes including the check engine light. Check engine light stayed on for several cycles then disappeared the next morning with no lights illuminated on the cluster. Truck is driving just fine however a friend of mine works at a Chrysler dealership and wanted a scan tool to see if there were any stored codes regardless if the onboard system stating otherwise. To my surprise the scan tool had brought up a laundry list of stored codes in the system. My friend told me that the only way to bring up these codes is with the engine running but cannot be cleared while the engine is running. Anyone else have this issue?
