SSM 506362022-03-29. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING; EQUIPMENT. 2011-2022 F-Super Duty and 2016-2023 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 505492022-03-08. Service bulletin. EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2018-2020 F-150, 2017-2022 F-Super Duty and 2016-2022 F-650/F-750 vehicles equipped with a diesel engine may exhibit diagnostic trouble code (DTC) P0000 stored in the powertrain control module (PCM) after an on-demand self test. This DTC is due to a processing error in the PCM as a result of on-demand self testing. P0000 is an invalid DTC that will not illuminate the malfunction indicator lamp (MIL) and no repairs should be performed.
SSM 504132022-02-04. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT. Some 2021-2022 F-650/F-750 vehicles may exhibit various electrical concerns due to an open high current mega fuse array in the high current battery junction box (BJB). Service part LU5Z-14526-B has been released for service. It is no longer necessary to order the complete BJB to obtain these parts.
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.
SSM 502182021-10-29. Service bulletin. SERVICE BRAKES; PARKING BRAKE:DRIVELINE:HYDRAULIC:ACTUATOR. Some 2021-2022 F-650/750, 2020-2022 Motorhome/Commercial Stripped Chassis vehicles built on or before 20-Sep-2021 with very low miles may experience parking brake drag. This condition typically occurs in less than 3000 miles (4800 kilometers). This condition may be identified even with the hand or pedal actuator mechanism disengaged. Inspect the park brake system for damage and replace parts as required per Workshop Manual (WSM) Section 206-05. If no damage if found, adjust the park brake cables and the park brake shoe adjuster per WSM, Section 206-05.
