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.
