16' with p218f code

[Rig Operator]

Hi all, have a friends 16' thats all stock with a def nozzle code p218f. Ran a cleaning cycle with snapon reader and system came back good. Still has power reduction code coming up on the trucks display. I did remove the code before the test with the scanner. So should I reset the scr data with the scanner? It was an option but said to do this only if the unit had been replaced.

Bump. Ran a forced regen on the truck today and all parameters good. Code did not come back, but still has power reduction warning on gauge display. At a loss here on what to do next. Scanner is a snapon modus.
