I have a 2006 5.9 Cummins and periodically usually while towing up a hill and transitioning down hill the grid heater light comes on with 10 dings and the truck looses power. I have to pull over and reset it as if it was a code to clear it up, even though there aren’t any codes. I have seen this talked about before but no one really came up with a solution. Anyone find out what causes this?
