Bulletins for this model year that name U3012
TSB 24-21472024-06-04. Service bulletin. 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.
SSM 525002024-05-17. Service bulletin. Some 2023 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble code (DTC) U3012 present in the powertrain control module (PCM). This may be due to the software in the body control module (BCM) and does not affect vehicle operation. To correct the condition, reprogram the BCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 15604 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 523892024-04-04. Service bulletin. Some 2022-2024 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with only diagnostic trouble code (DTC) U3012 stored in the PCM. If no drivability concerns or other DTCs are present, perform normal diagnostics per the Workshop Manual (WSM). If diagnostics lead to the powertrain control module (PCM) or body control module (BCM), the replacement of the PCM and/or the BCM will not resolve this concern. This illuminated MIL with DTC U3012 does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
