AS WITH ALL MY VIDEOS I TRY TO GIVE THE MOST INFORMATION IN THE LEAST AMOUNT OF TIME AS POSSIBLE SO I DON'T WASTE YOUR TIME. IN THIS VIDEO I HAD THE CHECK TRAILER WIRING COMING ON MY INSTRUMENT CLUSTER ON MY 2017 CHEVY 2500. IT HAS BEEN INTERMITTENLY GOING ON AND OFF BUT WAS GETTING DRASTICALLY WORSE TO THE POINT OF GOING OFF EVERY COUPLE OF MINUTES WHILE DRIVING. I GO OVER THINGS TO CHECK ON YOUR VEHICLE AND TRAILER THAT MIGHT BE CAUSING THIS AND I GO OVER THE REPLACEMENT OF THE ELECTRIC BRAKE CONTROLLER WHICH ENDED UP BEING THE PROBLEM IN MY TRUCK.
