What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025-2026 Bronco vehicles may exhibit a condition where cruise control is inoperative and/or an "Adaptive Cruise Control Not Available" message is displayed in the instrument panel cluster (IPC) with diagnostic trouble code (DTC) U0422:00 stored in the anti-lock brake (ABS) module. If a vehicle exhibits this condition, this may be due to an incorrect configuration programmed to the ABS module during an attempt to change tire size. <br /><br /> The Ford Performance ProCal 4 tool is the only approved tool that can be used for properly adjusting the tire size calibration. Vehicles originally equipped with 30-inch tires that are being upfit with 35-inch tires should be set to 615 revolutions per mile in the Ford Performance ProCal 4 tool under Diagnostics and Tools > Tire/Gear Adjust. Any other concerns related to tire size calibration that exhibit this condition, contact the Ford Performance Techline as outlined in the Ford Performance ProCal 4 tool instructions. <br /><br /> This limitation in tire size calibration is due to the software in the ABS module.
Trouble codes it names: U0422

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54856 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 54856 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 54856 cover?
The manufacturer filed it against 2 model years: 2026 Ford Bronco, 2025 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
