My 2020 Ram 1500 Ecodiesel has been great for 2.5 years, and now has 42k miles. Not one single problem ever. I pulled my 6000lb camper a total of 600 miles this past weekend, and dropped it off at storage Sunday eve. Drove it Monday, no issues. Today I get in the truck and get some warnings popping up on dash.....Service 4wd, Service Trailer brakes, and ESC service needed. It still drives smoothly and perfectly, no noises, etc. I took it to AutoZone and they plugged in the reader and got no engine codes. Is there any fix for these annoying lights? Also, I noticed my backup camera isn't working even when shifting into Reverse, using the icon, nothing. In the controls app the backup camera icon isn't even there anymore. I disconnected the negative battery terminal cable for about an hour hoping to reset things but it didn't work. Any thoughts? Thanks.
