Official summary
Some 2016-2019 F-Super Duty and 2016-2019 F650-750 vehicles equipped with 6.7L engine may exhibit a concern where the engine cooling fan stays on at all times or is inoperative. Diagnostic trouble codes (DTCs) P0480, P0494, P0495, P0529, P0691, P0692, P0693 and/or P0694 may be stored in the powertrain control module (PCM). To address these vehicle symptoms, use the updated online version of pinpoint test AH in the powertrain control/emission diagnostic (PC/ED) tab on the PTS website. The pinpoint test has been updated to aid in preventing unnecessary fan clutch replacement.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
