Just a thought. Maybe the crankcase pressure sensor malfunctions when you apply the exhaust brake? Regardless, changing the sensor would be my next step.

I am wondering if increased crankcase pressure when using the exhaust brake would be a symptom of one or more leaking exhaust valve seals. The fact that stage one does not cause a pressure alarm, but stage two does because it creates more back pressure in the exhaust manifold would suggest a leaking seal.

I know this is an old post, but were you ever able to fix the problem? Mine does exactly the same thing too, only a problem when I'm towing and use the engine brake. If I'm not towing a toad I can use the engine brake and it hasn't happened (so far). But it's definitely engine brake related for me as well.
