SSM 517502023-06-30. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Some 2023 F-Super Duty vehicles equipped with a 6.7L engine, and built on or before 02-May-2023, may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) U029D, U029E, U02A1, U02A3, P2209, P24D0, P22A7, and/or P23B5. This may be due to a wiring chafe on harness 14406 near connector C146 touching the exhaust gas recirculation (EGR) cooler on the right side of the engine. Before performing normal diagnostics, inspect 20 amp fuse F18 (position 26). If fuse F18 is found open, inspect the 14406 harness for contact with the EGR cooler and repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. If no damage is found, refer to Workshop Manual, Section 303-08A for normal diagnostics.
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.
