TSB 24-2147

Some 2021-2023 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) U3012 stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM and the transmission control module (TCM) if a TCM update is available.
