I have the same problem and all three engine lights are on. Def gauge was flashing red and now is flashing yellow. Still, all engine lights are on including the red one. I was able to get the truck to run and I perform a regen but the light are on and I’m on derate mode. Truck won’t go more than 5 mph. And advise you can offer me?
