Summary

Some 2023-2025 F-Super Duty vehicles may exhibit a "Hill Start Assist Unavailable" and/or "Parking Brake Limited Function" message at vehicle start-up with diagnostic trouble codes (DTCs) U0151, U023A, U0159, and/or U0146 stored in the anti-lock brake system (ABS) module. These DTCs and/or U0415 may also be present in various other modules related to "invalid data received from the ABS control module". This may be due to the software in the ABS module. To correct the condition, reprogram the ABS module using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 2C219 and labor operation 2219D and 2219D44.
