I never heard of a code for low fuel. Maybe a code for no fuel? Limp mode doesn't make sense either. I'm thinking it was some sort of glitch.Got it back from the dealer today. They said the code was P1E0C - empty fuel tank (WTF?!) I'm not a mechanic, but I'm not a complete idiot. Truck gave no indication of low fuel...gauge wasn't pegging in the red, no fuel indicator light, distance to empty in the EVIC showed more than 100 miles. Dealer said fuel light came on for them and they banged on the tank and it sounded empty. They added fuel and drove it for about 30 miles and didn't receive any additional warnings. Hoping it was just a small glitch...
Thanks for testing the dealer with the GDE Tune.
