Manufacturer summary

Original wording in English

Some 2017-2021 F-Super Duty vehicles equipped with a 6.7L diesel may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2459, P246C and/or P2463 with a Drive to Clean maintenance message. Vehicles operated primarily in a stationary or off-highway low speed use may exhibit frequent exhaust regeneration attempts. In these conditions, a vehicle may not easily allow for normal exhaust regeneration and may benefit from operator commanded regeneration (OCR) capability so it can perform complete exhaust regeneration in a stationary setting.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
