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.
TSB 19-20972019-05-06. Service bulletin. ENGINE AND ENGINE COOLING. Some 2015-2019 Transit vehicles equipped with a 3.5L or 3.7L engine may exhibit a lack of heat or uneven heat from side to side. This condition may be due to deposits from the engine coolant becoming trapped in the heater core. To correct the condition, flush the cooling system and replace the heater core.
TSB 19-20162019-04-08. Service bulletin. ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE; ENGINE. Some 2016-2018 Transit vehicles equipped with a 3.2L Duratorq diesel engine and built on or before 13-Feb-2018 may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P24A0 and/or P26A0 in the powertrain control module (PCM). Follow the Service Procedure steps to correct the condition.
TSB 19-20912019-04-02. Service bulletin. POWER TRAIN; ENGINE. Some 2015-2018 Transit vehicles built on or before 24-Jul-2018 may exhibit various drivability concerns including difficulty starting, misfires and/or an illuminated MIL with diagnostic trouble codes (DTCs) P00BD, P1247, P1548, P061B, P2195, P2198, P2196, P2197, P0171, P0172, P0174, P0175, P0131 and/or P162F stored in the powertrain control module (PCM). This may be due to undesired water entry into the engine compartment directly over powertrain components. To resolve this condition, install updated water management hardware and/or a revised air cleaner cover.
TSB 19-20612019-04-02. Service bulletin. POWER TRAIN; ENGINE. Some 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may exhibit Drive To Clean maintenance messages and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2459, P2463, and/or P246C. Vehicles may also exhibit frequent automatic exhaust regeneration attempts. This may be due to vehicles being used in stationary or off-highway, low speed applications. If automatic regeneration attempts are unsuccessful, these symptoms may be a result of soot accumulation in the diesel particulate filter (DPF). These vehicles may benefit from operator commanded regeneration (OCR) capability so complete regeneration cycles may be performed in a stationary setting. Some 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may exhibit Drive To Clean maintenance messages and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2459, P2463, and/or P246C. Vehicles may also exhibit frequent automatic exhaust regeneration attempts. This may be due to vehicles being used in stationary or off-highway, low speed applications.

SSM 477122019-03-04. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; FUEL SYSTEM, DIESEL. Some 2017-2019 F-Super Duty and 2016-2019 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2019 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.
SSM 476622019-01-07. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. 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. For all turbocharged engine applications, the turbocharger oil supply filter (6C683 gas engine/6L625 connector style or 6A968 diesel engine) 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 476412019-01-07. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE); ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. Some 2011-2019 F-Super Duty, 2015-2019 Transit, 2016-2019 F-650/F-750 and 2018 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 aftertreatment system. Use of these cleaning tools may void the emissions warranty of the hot end aftertreatment exhaust system and the attached emissions sensors.
SSM 475272018-12-03. Service bulletin. ENGINE AND ENGINE COOLING. Some 2015-2019 Transit vehicles may have unique accessory drive noise characteristics. Engineering review of warranty returned belt tensioners has not identified an out of specification part, nor have abnormal sounds been recreated during on-vehicle evaluations with warranty returned tensioners. Before attempting a repair for an accessory drive system noise, compare the sound to a like Transit vehicle in similar RPM and temperature conditions. If the sound is not characteristic, use chassis ears to help isolate the source of the noise. If tensioner replacement is deemed necessary, use the Report a Vehicle Concern link at the bottom of the vehicle's OASIS screen and submit a detailed Global Concern Report highlighting the specific conditions when the noise was observed.
SSM 476132018-11-19. Service bulletin. ENGINE. Some 2018-2019 Transit vehicles equipped with a 3.2L engine may exhibit an illuminated MIL with DTC P054E. If DTC P054E is set with any other DTCs, diagnose and repair those DTCs first. If DTC P054E is the only DTC, do not attempt to repair or replace any components, Engineering is investigating. To assist with the investigation, while IDS is open, access Powertrain > OBD Test Modes > Mode 9. Once open, log the data, exit, and save and hold the session. Next, open the Previous Sessions menu, highlight the respective session, and press the session upload icon (three computers) to transmit the file.
