Service bulletins for the 2021 Ford F-550

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 547202026-04-10. Service bulletin. ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. Various 2020-2026 Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z-14A411-B to resolve the concern.

SSM 543132025-10-28. Service bulletin. LANE DEPARTURE: BLIND SPOT DETECTION; ELECTRICAL SYSTEM. Some 2020-2025 various Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z-14A411-B to resolve the concern.
TSB 23-20822023-04-04. Service bulletin. POWER TRAIN; BACK OVER PREVENTION:SOFTWARE. Some 2020-2022 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0315, P054F, P054E, P2A00, P2A01, and/or P02ED stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM and the transmission control module (TCM).
SSM 512632023-01-06. Service bulletin. BACK OVER PREVENTION; STRUCTURE:BODY:DOOR. Some 2015-2023 F-150, 2017-2022 F-Super Duty, and 2019-2023 Ranger vehicles may exhibit dust ingress into the cabin through the doors or air extractors. This may be due to the climate control system being in recirculation mode as a result of the recirculation button being on or automatic strategies for heating/cooling efficiency. To minimize dust ingress when driving in off-road or secondary road conditions, make sure that all doors and windows are fully closed and the climate control system is switched to defrost on and the instrument panel and footwell air vents are switched to off. Temperature and fan settings may be adjusted as desired. Alternatively, max defrost can be activated which will adjust all settings automatically. Operating in defrost mode will keep constant air flow through the rear air extractors and other small areas, helping minimize dust ingress.
TSB 22-22542022-07-01. Service bulletin. BACK OVER PREVENTION:SOFTWARE. Some 2019-2020 Edge/F-150/Fusion/Continental/MKZ/Nautilus, 2019-2021 Mustang/Ranger/Transit Connect, 2020-2021 EcoSport/Escape/Expedition/Explorer/F-Super Duty/Aviator/Corsair/Navigator, 2021 Bronco Sport and 2020-2022 Explorer/Aviator vehicles with SYNC 3 may experience various SYNC performance related concerns. This may be due to the SYNC Software. To correct the condition, follow the Service Procedure to update the accessory protocol interface module (APIM) software.
SSM 503882022-02-04. Service bulletin. LANE DEPARTURE: SENSING SYSTEM: CAMERA; FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA; ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Some 2020-2022 F-Super Duty/Explorer/Aviator and 2021-2022 F-150 vehicles may exhibit a Front Camera Fault, Lane Keeping Fault, and/or Collison Warning Not Available message with various diagnostic trouble codes (DTC) stored in the image processing module A (IPMA). If programming fails or Ford Diagnosis and Repair System (FDRS) states a file failed to flash after replacing the IPMA or reprogramming IPMA software, test the battery using any approved Rotunda tool including the GR-190, GRX-3590, and DCA-8000. Fully recharge or replace the battery according to results of the tool. Set the battery charger to maintain battery voltage between 12.6 and 13.6 volts during the entire programming procedure. The IPMA programming procedure may take several hours to complete due to the size of the software files required.
SSM 497562021-05-03. Service bulletin. BACK OVER PREVENTION:SOFTWARE. Some 2018-2021 vehicles supported by FDRS may not list a software update for a module under the SW Updates tab although an SSM or TSB is published for a software update. This may be due to the module already being at the latest software level. A later software level may have been programmed at the assembly plant, during a previous dealer visit or by an over the air (OTA) update for vehicles that have automatic updates enabled in the SYNC system settings. To review a vehicle's OTA update history, visit the Connected Vehicle > OTA Dashboard tab in OASIS. Information about the OTA Dashboard can be found on FMCDealer.com when performing a search on OTA History Job Aid.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
