Sounds like you need to update your DashDAQ. Try this:

Tech Support - How do I update my DashDAQ?

This is what I found on your code:

P2455 X
Diesel Particulate Filter Differential Pressure Sensor Circuit High - This error occurs if a short to power occurs in the diesel particulate filter differential pressure sensor circuit. Did you mess up any of your sensors??? Are they all the way plugged in? Sending you a pm....

When I first installed my DD before I messed with my DPF and even before loading a tune my truck threw that code. I cleared it about 5 times while driving around and it shutoff and since I installed everything it hasn't come's like it knew I was about to get rid of it hahahaha
