SSM 54856

Some 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.
