Service bulletin SSM 45897

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.

SSM 54601	2026-02-27. Service bulletin. Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k
SSM 52335	2024-03-20. Service bulletin. For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
TSB 22-2248	2024-03-07. Service bulletin. This article supersedes TSB 22-2201 to update the Service Procedure and Parts List. Some 2015-2019 F-Super Duty and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, or upper/lower oil pan. This may be due to the mating surfaces of the upper oil pan and the engine block or to a clogged crankcase vent oil separator.
SSM 52167	2024-01-18. Service bulletin. Some 2017-2019 F-Super Duty pick-up vehicles may require the additional KC3Z-14A411-C kit if there is a service need to replace the 14405 main body harness or 14A412 tailgate harness post FSA 19S48. During the FSA 19S48 repair, additional connectors are added to the 14405 and 14A412 that utilize the jumper service kit contained in the FSA. Direction regarding the need for this harness is also noted in the Ford parts catalog.
SSM 51691	2023-06-16. Service bulletin. 2011-2023 F-Super Duty and 2016-2024 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.
TSB 23-2161	2023-05-31. Service bulletin. Some 2018-2021 F-150 vehicles equipped with a 3.0L diesel engine, 2016-2022 F-650/F-750 vehicles equipped with a 6.7L engine, and 2017-2022 F-Super Duty vehicles equipped with a 6.7L engine and built on or before 08-Mar-2022 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P21DD, P20BA. P20B9, P204C, P208A, P208B, P208C, P203B, P205B, P21CD and/or U02A2 in the powertrain control module (PCM). This may be due to water intrusion within connectors C3613 and/or C4851/C3610 on the reductant harness going to the reductant pump/heater assembly and the reductant level sensor/quality module. This may also be due to movement of the wiring harness causing terminal fretting. To correct the condition, follow the Service Procedure to replace the reductant tank harness, the reductant pump/heater assembly and/or the reductant tank, as well as securing the wiring harness using a cable zip tie fastener.
SSM 51294	2023-01-31. Service bulletin. Some 2016-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L engine may require the lower intake manifold to be removed for various concerns. The WSM, Section 303-01, has been updated to remove the lower intake manifold leaving the crankcase vent oil separator attached. Both parts should be removed from the engine together to avoid discarding and replacing the crankcase vent oil separator.
TSB 22-2380	2022-10-31. Service bulletin. Some 2017-2019 F-Super Duty chassis cab/dual rear wheel (DRW) pickup vehicles and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit a concern of oil consumption in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted. To correct the condition, follow the Service Procedure to replace the crankcase oil separator and to inspect the turbocharger to determine whether the turbocharger needs to be replaced. Note: The new crankcase vent oil separator appears different from the old crankcase vent oil separator as it no longer includes a serviceable filter element.
TSB 22-2223	2022-06-13. Service bulletin. Some 2017-2019 F-Super Duty chassis cab/dual rear wheel (DRW) pickup vehicles and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit a concern of oil consumption in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted.
