X15 derate due to clogged fuel filter

[tree98]

So I was able to get an active fault code out of this X15 with an obd reader and a cummins app on android. It's Active fault 559 (engine injector metering rail 1) Looks to me like what happened is the Davco filter was plugged and it triggered the fault due to low fuel pressure. I changed the filter but The CEL is still on and it's still in derate (won't rev higher than 1400 rpm) Do I need to clear the code before it will get out of the derate? I don't currently have working insite to clear it, is ther another way?
