Service bulletin TSB 21-2198
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some 2021 F-650/F-750 vehicles equipped with a 7.3L engine may exhibit various electrical concerns and/or various illuminated warning lamps with various diagnostic trouble codes (DTCs) present. This may be due to the powertrain control module (PCM) wiring harness contacting the air conditioning (A/C) compressor inlet line. To correct the condition, follow the Service Procedure to repair any damaged circuits and secure the PCM wiring harness to the main wiring harness.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
| SSM 50977 | 2022-08-02. Service bulletin. Some 2021-2022 F-Super Duty and 2021-2023 E-Series vehicles equipped with a 6.2L or 7.3L gasoline engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0457 stored in the powertrain control module (PCM). This may be due to a loose fuel filler cap. The fuel filler cap design has changed, requiring multiple turns to seal properly. Advise the customer to turn the fuel filler cap clockwise until there is at least one audible click to seal properly. For further diagnostics, refer to Workshop Manual (WSM), Section 303-13 - pinpoint test HX. |

| SSM 50636 | 2022-03-29. Service bulletin. 2011-2022 F-Super Duty and 2016-2023 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages. |
| SSM 50549 | 2022-03-08. Service bulletin. Some 2018-2020 F-150, 2017-2022 F-Super Duty and 2016-2022 F-650/F-750 vehicles equipped with a diesel engine may exhibit diagnostic trouble code (DTC) P0000 stored in the powertrain control module (PCM) after an on-demand self test. This DTC is due to a processing error in the PCM as a result of on-demand self testing. P0000 is an invalid DTC that will not illuminate the malfunction indicator lamp (MIL) and no repairs should be performed. |
