Not sure what else I can give. I have 2009 Freightliner, Detroit engine with about 800k miles. I have had many issues with this truck. Last week, the stopped running. I took it to The Freightliner shop for repairs, would auto regen.This morning the driver informed that was a code "?" showing; the truck would not run - no power. The checked out the truck. There was loud air release. He could not detect the location of the air leak.Once the air leak stopped the truck now runs. I guess I should be happy. I am. But want to know what the code indicator was and the air release.I have not other details.

What model is the Freightliner? Is it a Cascadia? Columbia? Century? Classic? Coronado? M2? There are many...

There is no question mark on the dash for any of them as far as codes go. There is one that has a exclamation point "!" inside a triangle for the ATC control, but I've never seen a question mark on the dash.

If it is the ATC then it was an issue with the brake system leaking and the rollover protection detected it. That is assuming you have a Cascadia.
