Paccar mx-13 clearing derate
Paccar mx13 epa13, Nox outlet sensor replaced, regen completed successfully. Code has disappeared after repair, however derate will not clear. Unfortunately I dont have access to Davie-4, wondering if anyone has any ideas how to complete a proper drive cycle to clear the derate(5mph max)? Or access to davie-4? Thanks

Hello fellas
Same thing happened to me today after repairs, couldn’t get truck out of derate.
Didn’t have DAVIE 4. Any other tricks?

Remove ECM and take it to nearest stealers%it to have re-flashed?.
