Issues with Kenworth T660 regen

Is it possible that they did something else to it when they went into the computer?

 

I have a 2014 T-660. Ive had alot of issues with my dpf system. There's a trick to it. The circuit breaker that puts power to the after treatment system gets a little loose and makes everything go haywire. Chck engine light comes on says D-rate on screen also. Park shut your engine off pop the hood open the circuit breaker box on the left side of the fire wall remove the circuit breaker for after treatment power(top right) then push it back in give it a light tap with your hand. Start it up and wala nothing is on anymore. If you turn your torque and hp all the way up you will have less problems as well. I have a 500 ISX Cummins.
