TSB 24-2122

This article supersedes TSB 23-2276 to update the Title, Issue Statement, and Action Statement to clarify the vehicle applications. Some 2021-2023 F-150 vehicles equipped with a 2 kilowatt (kW) (not 400 watt (W)) direct current/alternating current converter module A (DCACA) inverter (minor feature code HUKAK) may exhibit an illuminated tire pressure monitoring system (TPMS) indicator with diagnostic trouble code (DTC) B124D:02 stored in the BCM. This may be due to the DCACA inverter causing radio frequency interference (RFI). 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).
