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 509742022-08-02. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; EQUIPMENT; ELECTRICAL SYSTEM:SOFTWARE. Some 2020-2022 Escape/Corsair/F-53 Motorhome/F-59 Commercial Stripped Chassis, 2021-2023 F-650/F-750/E-Series, and 2021-2022 Bronco Sport vehicles may exhibit a communication fault with emissions inspection equipment. This may be due to the software in the gateway module (GWM). To correct this condition, reprogram the GWM to latest software level using the appropriate Ford diagnostic scan tool. Use causal part 14F642 and applicable labor times from Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 498052021-06-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING. Some 2011-2021 vehicles equipped with a diesel engine may have engine oil in the exhaust after turbocharger replacement for various reasons. To correct the condition, remove the exhaust and stand the exhaust up with the turbocharger inlet side facing down using a suitable drain pan. Allow the exhaust to drain for at least 24 hours and reinstall. Do not perform a manual exhaust regeneration.
SSM 491852020-10-06. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV); ELECTRICAL SYSTEM. Some 2020 F-Super Duty and 2021 F-650/F-750 vehicles equipped with a 6.7L diesel engine built on 01-Mar-2020 and through 31-Aug-2020 may exhibit an illuminated malfunction indicator light (MIL) with diagnostic trouble code (DTC) P0088. This may be due to the pressure control valve in the left fuel rail. To correct the condition, replace the left fuel rail along with the pressure control valve (PCV). For F-250 through F-550 vehicles refer to Workshop Manual (WSM), Section 303-04B. For F-650/F-750 vehicles refer to WSM, Section 303-04A. For claiming use causal part 9D280 and applicable labor operations in Section 09 of the Service Labor Time Standards (SLTS) Manual.
