2013 ISX15 485 check engine and regen flash

[Scotty32]

Oh ok. Since i did the regen this morning it has not come up. However the yellow engine with the wrench is still lit. I did notice when i shut the truck off that the def pump at the tank was making noise for about 20 seconds then shut off. I cycled the key and the pump.made noise then got quiet and was still pumping so i dont know whats going on with that. But fuel mileage is struggling at 3.9 to 4.2.
