Official summary
Some 2021-2022 F-150 vehicles may exhibit all modules on the HS2, HS3, HS4 and MS CAN networks not responding to the Ford Diagnosis and Repair System (FDRS) and modules on these networks fail the network test. Modules on the FD1 and HS1 networks will communicate with the FDRS. Vehicles equipped with a power opening/closing tailgate may also exhibit an inoperative power tailgate. This may be due to a gateway module (GWM) that is not configured properly. To correct this condition, download and run the GWM - Gateway Module A (GWM) Configuration application. For claiming, use causal part number 14
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
