Official summary
Some 2023-2024 F-Super Duty vehicles may require a replacement of the anti-lock brake system (ABS) module for various reasons. Replacing the ABS module may result in an error state with diagnostic trouble code (DTC) C0020:64 stored in the ABS module due to the Ford Diagnosis and Repair System (FDRS) software. If directed to replace the ABS module (2C219) during normal diagnostics in the Workshop Manual, replace the complete ABS module/hydraulic control unit (2C215) instead to avoid this error state. Monitor OASIS for updates.
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.
