Manufacturer summary

Original wording in English

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 (DTC) 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". Replacement or reprogramming of the ABS module will not resolve this condition. There is no effect to the parking brake or other vehicle functions. This does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q3 2025. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
