TSB 23-2407

Some 2021-2022 F-150 vehicles equipped with a direct current/alternating current converter module A (DCACA) inverter (minor feature code HUKAK) may exhibit a Pro Power Onboard Unavailable message in the vehilce center display screen with DTC B15DA:09 in the BCM. This may be due to the software level of the BCM and powertrain control module (PCM). To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). To correct this condition, perform the Service Procedure below to reprogram the BCM and PCM to the latest software level via the Ford Diagnosis and Repair System (FDRS).
