TSB 21-24522022-01-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2020-2021 Aviator vehicles equipped with a 3.0L PHEV powertrain may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) U0100, P1A42 and/or P1A43 stored in battery energy control module (BECM). This may be due to software in the PCM. To correct the condition, follow the service procedure to perform a coordinated flash on the powertrain control module (PCM), secondary on-board diagnostic module c (SOBDMC), anti-lock braking system (ABS) module, BECM, and battery charger control module (BCCM).
TSB 21-24472022-01-01. Service bulletin. ENGINE AND ENGINE COOLING. This article supersedes TSB 21-2192 to update the Parts List and Issue. Some 2017-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L may exhibit an engine oil leak. This may be due to the mating surface of the upper oil pan and the engine block. To correct the condition, follow the Service Procedure to reseal the engine block.
SSM 503232021-12-26. Service bulletin. ENGINE AND ENGINE COOLING. Some 2017-2022 F-Super Duty and 2016-2022 F-650/F-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2021 F-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM). Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid (DEF) concentration. Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.
TSB 21-23362021-10-05. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM; ENGINE. Some 2018-2020 F-150 vehicles built on or before 1-Apr-2020 equipped with a 3.0L diesel engine, 2017-2019 F-Super Duty vehicles built on or before 30-Oct-2019 equipped with a 6.7L engine and 2016-2019 F-650/F-750 vehicles built on or before 30-Oct-2019 equipped with a 6.7L engine 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. To correct the condition, follow the Service Procedure steps to replace the reductant tank harness, the reductant pump/heater assembly and/or the reductant tank.
20M06-S12021-09-30. Service bulletin. ENGINE. Certain 2015 through 2016 Model Year Super Duty and 2016 through 2019 Medium Duty with 6.7L Diesel Engine Diesel Particulate Filter Warranty Extension with Diagnostic Trouble Code P2002

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, upper/lower oil pan. This may be due to a clogged crankcase vent oil separator and/or a sealing concern. Do not remove/replace the engine front cover for upper oil pan leaks. Do not check for warpage on the upper oil pan. When the upper oil pan is not bolted to the vehicle, it has a natural tendency to twist slightly due to the manufacturing process for the pan and will not result in an oil leak. The Workshop Manual (Section 303-00 > Diagnosis and Testing > Engine > Engine Oil Leaks) provides information on the usage of fluorescent oil dye to locate the source of an oil leak. Refer to GSB Oil Leaks Weeps And Seeps for more oil leak diagnosis. Continue to monitor OASIS for updates.
TSB 21-21922021-09-02. Service bulletin. ENGINE AND ENGINE COOLING. Some 2017-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L may exhibit an engine oil leak. This may be due to the mating surface of the upper oil pan and the engine block. An oil leak in this area may also be influenced by a blocked crankcase oil vent separator. To correct the condition, follow the Service Procedure to reseal the engine block.
SSM 498462021-07-02. Service bulletin. FUEL SYSTEM, GASOLINE. Some 2017-2019 F-Super Duty/F-650/F-750 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P24D1 stored in the powertrain control module (PCM).

Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.
SSM 494302021-02-04. Service bulletin. ENGINE AND ENGINE COOLING. 2011-2021 F-Super Duty and 2016-2021 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit a high/elevated idle condition. During prolonged idle time, vehicles may experience this high/elevated idle to reduce buildup of unburned hydrocarbons from the SCR system. The powertrain control module (PCM) estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 revolutions per minute (rpms) for ambient temperatures near 26C (80F) and may increase to as high as 1200 rpms at -40 C (-40F). These elevated idle periods can last from 20-40 minutes, depending on ambient temperatures. During power take off (PTO) use and already using idle set point control, the elevated speed is disabled. It is required that the operator monitor the vehicle and adhere to the Exhaust Filter warning messages.
SSM 492102020-10-06. Service bulletin. ENGINE AND ENGINE COOLING. Some 2009-2020 Ford and Lincoln vehicles equipped with turbochargers may exhibit an oil leak from the turbocharger oil supply or return tubes, O-rings or 6.7L pedestal gasket. Although oil may collect on the turbocharger, it is very rare for a turbocharger to leak oil. To isolate the source of the leak, refer to Workshop Manual (WSM), Section 303-00 General Information > Diagnosis and Testing > Engine > Engine Oil Leaks - Fluorescent Oil Additive Method procedure. When an oil leak is present at a turbocharger oil supply or drain tube, remove the affected oil tube and inspect for damage, and replace the O-ring seals, pedestal gasket or oil tube as required. Refer to WSM, Section 303-04. For claiming, use the affected oil tube or pedestal gasket as the causal part and applicable labor operations in Sections 6 and 9 of the Service Labor Time Standards (SLTS) Manual.
TSB 20-22672020-10-01. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:ADAS:DRIVER MONITORING:CAMERA/SENSOR. Some 2015-2020 F-150 except Raptor, 2017-2020 F-Super Duty, 2018-2020 Expedition vehicles equipped with a front camera washer may exhibit a washer fluid leak at the front camera washer jet when not in use. This may be due to the rubber seal internal to the jet. To correct the condition, follow the Service Procedure to replace the washer jet.
SSM 490652020-09-04. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; FUEL SYSTEM, DIESEL. Some 2011-2020 F-Super Duty, 2015-2019 Transit, 2016-2021 F-650/F-750 and 2018-2020 F-150 vehicles equipped with a 6.7L, 3.2L or 3.0L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P207F, P20EE, P229F, P2201 and/or P24AE. This may be a result of using aftermarket cleaning liquids or tools for the exhaust gas recirculation (EGR) cooler or intake. Ford does not recommend the cleaning of diesel intakes or EGR coolers using any aftermarket tool that injects a cleaning foam or liquid substance into the EGR cooler or intake. Using these types of fluids can result in sodium poisoning of the NOx and particulate matter (PM) sensors resulting in degraded operation and permanent damage to the after treatment system. Use of these cleaning tools may void the emissions warranty of the hot end after treatment exhaust system and the attached emissions sensors.
SSM 484502020-02-04. Service bulletin. SERVICE BRAKES. Some 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine and an air brake system may exhibit inoperative cruise control and/or immediate transmission downshifting when releasing the accelerator pedal. This may be caused by an in range failure of the brake pedal pressure transducer (7920) that does not set a diagnostic trouble code (DTC). The Integrated Diagnostic System (IDS) can be used to view the WHEEL TRQ RAW PID in the generic function module (GFM). It displays the voltage value of the brake pedal pressure transducer. The voltage should be between 0.35 volts and 0.65 volts with the brakes released and will increase with brake pedal pressure. An inoperative transducer will not change with brake pedal pressure. Refer to Workshop Manual (WSM), Section 206-08 for the location of the brake pedal pressure transducer.
TSB 20-20122020-02-04. Service bulletin. POWER TRAIN. Some 2017-2019 F-650/F-750 vehicles equipped with a 6.7L engine, 6R140 transmission and hydraulic brakes may exhibit a driveline vibration typically during the 1500-1700 engine revolutions per minute (RPM) range. To correct the condition, follow the Service Procedure to reprogram the powertrain control module (PCM).
SSM 482992019-12-04. Service bulletin. SERVICE BRAKES, HYDRAULIC. Some 2016-2019 F-750 vehicles may exhibit an excessive or uneven amount (inner versus outer) of front and/or rear brake pad wear. For vehicles exhibiting this condition, it's recommended to use FC4Z-2001-F brake pad kit when replacing front or rear pads. Some vehicle applications will demonstrate improved brake pad wear after installing this kit.
SSM 481232019-09-06. Service bulletin. ELECTRICAL SYSTEM. For Ford and Lincoln vehicles that require positive or negative battery terminal replacement, it is not necessary to replace the complete battery cable harness (14300 and 14301) for this concern. Positive battery cable clamp BT4Z-14450-AA and negative battery cable clamp BT4Z-14450-BA are available for this type of repair. Do not cut or shorten the battery cable, instead carefully remove the affected battery cable clamp and clean the cable end as necessary to preserve wire length. Some rework may be necessary for some vehicle environments. Bend the new positive battery cable clamp as needed and crimp it to the existing battery cable. Make sure to use heat shrink tubing over the battery cable to battery cable clamp connection. Obtain the heat shrink tube locally.
SSM 479992019-06-07. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN. 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.
SSM 479762019-06-07. Service bulletin. POWER TRAIN. On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.
TSB19-21422019-06-05. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). 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 steps to replace the crankcase oil separator. The new crankcase vent oil separator appears different from the old crankcase vent oil separator as it no longer includes a serviceable filter element. Follow the service procedure steps to correct the condition.
SSM 479482019-05-07. Service bulletin. ENGINE. SSM 47948 - 2010-2019 Various Vehicles - Turbocharged Engines - Oil Supply Filter Replacement When Replacing The Turbocharger Or The Turbocharger Oil Supply Tube For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. When specified in the WSM, the turbocharger oil supply filter must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter.
SSM 478362019-04-08. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:ENGINE:DIESEL. Some 2011-2019 F-Super Duty 6.7L diesel equipped vehicles may exhibit a ticking/tapping noise traced to the reductant injector.
SSM 478232019-04-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE. 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> OASIS> 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.
