Service bulletin SSM 50636

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

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.

Other bulletins for the same vehicles and component
SSM 523892024-04-04. Service bulletin. Some 2022-2024 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with only diagnostic trouble code (DTC) U3012 stored in the PCM. If no drivability concerns or other DTCs are present, perform normal diagnostics per the Workshop Manual (WSM). If diagnostics lead to the powertrain control module (PCM) or body control module (BCM), the replacement of the PCM and/or the BCM will not resolve this concern. This illuminated MIL with DTC U3012 does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
TSB 24-20662024-04-03. Service bulletin. This TSB supersedes article 24-2036 to update the vehicles affected. Some 2023-2024 F-Super Duty pickup vehicles built on or before 02-Jan-2024 equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0133, P0139, and/or P0145 stored in the powertrain control module (PCM). This may be due to the software in the PCM and does not affect vehicle operation.
SSM 522992024-03-05. Service bulletin. Some 2023-2024 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) U02A2, P206B, P203B, P208A, P20FA, P20FD, and/or P20FC stored in the powertrain control module (PCM). Before performing normal diagnostics, inspect connectors C1273C (32 pin) and C406 (14 pin) for proper connection. Also disconnect and inspect C1415 (32 pin), C406 (14 pin), C4863 (7 pin) and C4864 (5 pin) on the 14405 vehicle harness for signs of terminal push out, water intrusion and/or corrosion. Refer to the Wiring Diagram for connector locations. Repair as necessary. Refer to Wiring Diagram Cell 005 for repair procedures.
TSB 23-23762024-01-05. Service bulletin. Some 2022 F-550 and F-600 F-Super Duty vehicles equipped with a 10R140 automatic transmission and 6.7L diesel engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTCs) P2704 and P0771 stored in the transmission control module (TCM) with poor shift quality and over 5,000 miles (8,000 km) in service. This may be due to wear between the input shaft and the E clutch hub causing the input shaft O-rings to become damaged resulting in an open E clutch circuit. To correct this condition, follow the Service Procedure to replace the E clutch hub and input shaft O-rings.

SSM 518542023-09-04. Service bulletin. Various 2013-2019 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P264F after powertrain control module (PCM) replacement. This DTC indicates that the engine serial number (ESN) must be programmed into the PCM. The ESN is located on PTS > Diagnostics tab > HVBoM > Features > Engine Serial Number. Once the ESN is obtained from the historical vehicle bill of materials (HvBOM), it can be programmed into the PCM using the appropriate Ford diagnostic scan tool. Navigate to the toolbox tab> powertrain menu> Service Functions> ESN.
