ABS, Trailer Brake, and Brake light turn on with Chekc ABD system and Trailer brake after I drive a few miles

[Launcher270]

2016 Ram 1500 w/ 3L Ecodiesel Limited model. I bought this truck last year and love it. not a problem with it till now. I had been on a long trip of around 1,000 miles and at the end of the trip, these lights came on with the warnings of check the ABS and trailer brake systems. I pulled over, turned the truck off and inspected the wiring but could not see any obvious issues. I started the truck and no lights or warnings. I drove the rest of the time with no issues. The next day, I drive a few miles and the warnings show up again. I turn the truck off and restart and not more warnings appear. Later they reappear. Very frustrating. One item of note is during the trip, my rear tires slipped on some lose gravel at an intersection and the slip light came on for a second but the ABS never engaged on the trip. I also checked my tires and they are getting worn. I tried several of the items listed in this forum to "reset" the system but nothing works. I plan to take it to the dealer to see if this is a common issue and see if its needs a reflash or something of that nature. Also I will ask them to theri test gear to see if my ABS sensors are still working. I would also assume this could be a wiring issue somewhere which means a long weekend checking wring if the dealer can't find the issue. I see other similar issues but nothing like this ghost issue that shows oup at random times.

Sounds like you have the right idea. The dealer tech will probably check codes first, and maybe a specific wheel sensor will have set a multiple fault codes. That's the most likely cause. Hopefully he'll check (carefully) the wiring to the sensors too as they can sometimes be an issue. Hopefully it'll be resolved right away. Sometimes intermittent issues can be trickier to resolve. Let us know what the fix was.
