SSM 550982026-08-25. Service bulletin. UNKNOWN OR OTHER; POWER TRAIN; ENGINE. Some 2013-2016 Super Duty vehicles equipped with a 6.7L diesel engine and 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may not pass a state smog test due to the exhaust gas system (EGS) monitor that will not run after completing the exhaust gas sensor drive cycle located within Section 2 of the Powertrain Control/Emissions Diagnostics (PC/ED) Manual > Drive Cycles. This may be due to the vehicles diesel oxidation catalyst (DOC) age counter being under the 120-minute age requirement. There is an all-new "PCM Catalytic Converter Age Evaluation" application within the latest version of the Ford Diagnosis and Repair System (FDRS). Use this new FDRS application to determine the age (in minutes) of the DOC. If the age is less than 120 minutes, perform manual regenerations to increase the catalyst age counter to satisfy the monitor age requirement. If further assistance is needed, contact the technical assistance center (TAC). Note: this article only applies to the EGS monitor. Problems with other vehicle monitors not running successfully must be addressed using normal diagnostics located i

TSB 22-22482024-03-07. Service bulletin. ENGINE AND ENGINE COOLING. 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 521882024-01-24. Service bulletin. STEERING. 2024 F-Super Duty vehicles are equipped with XL-22 (WSS-M2C184-A1) high temperature power steering fluid that looks like clear hydraulic fluid. This fluid is an improvement in high temperature and thermal oxidative stability compared to Mercon LV. This power steering fluid is also compatible and highly recommended to use when filling or topping off power steering systems of all 2012-2023 F-Super Duty vehicles originally equipped with Mercon LV.
SSM 519472023-10-06. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Some 2015-2019 F-Super Duty and 2015-2020 F-150/Mustang vehicles may require replacement of the powertrain control module (PCM) for various reasons. While performing a programmable module installation (PMI) using the Integrated Diagnostic Service (IDS) scan tool, an error message may state: Configuration Failed, Would You Like To Retry? This may be due to improper module replacement steps. Make sure that the original module is installed in the vehicle, delete the vehicle session, then start a new vehicle session. Once the session starts, run the PCM PMI and install the new PCM only when the scan tool instructs. Finish the PMI by following the prompts given by IDS. If the original PCM is not available, it is possible to configure the module by running as-built programming on the PCM. When IDS asks to obtain part numbers or configuration data, select configuration data.
SSM 518542023-09-04. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). 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.

SSM 516912023-06-16. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 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.
SSM 515362023-05-04. Service bulletin. STRUCTURE. For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.
SSM 512512023-01-05. Service bulletin. ENGINE AND ENGINE COOLING. Some 2011-2022 F-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit a ticking noise at idle after an engine oil change. It is often referred to as Typewriter Noise because of its similarity to the sound of a mechanical typewriter. When engine temperatures reach 150 °F (65 °C) or higher, (from engine idle up to approximately 1700 RPM's), this noise can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. Typewriter Noise is not detrimental to engine function or durability and has no short or long term effects on the engine. Do not attempt repairs to eliminate this noise. This noise is characteristic of the 6.7L diesel engine and will typically cease or diminish significantly within the oil change maintenance interval.
TSB 22-23562022-09-30. Service bulletin. POWER TRAIN. Some 2015-2019 F-Super Duty vehicles may experience a transmission fluid leak from a cracked transmission case or transmission fluid pan. This may be due to a driveline vibration condition. For vehicles that have a concern with a cracked transmission case (Figures 1-2) or fluid pan (Figures 3-4), the rear driveline imbalance most often is the root cause of this concern. To correct the condition, follow the Service Procedure to replace the rear driveline.
SSM 508042022-06-01. Service bulletin. ELECTRICAL SYSTEM. Some 2013-2023 Ford or Lincoln vehicles with modems activated through FordPass or LincolnWay may experience 12 volt battery drain symptoms when the customer uses non-Ford/Lincoln phone applications as an alternate channel to access vehicle commands such as door lock/unlock, remote start, vehicle location, etc. The battery drain may be caused by excessive calls for data through the vehicle network keeping it in an activated state. Recommend that the customer uninstall the app to ensure this is not contributing to battery symptoms experienced. Advise the customer that unaffiliated third-party app developers do not work directly with Ford to adhere to security, vehicle communication, and privacy requirements.
