Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
