Service bulletins for the 2023 Ford F-450

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 523892024-04-04. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). 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.
TSB 24-20552024-04-03. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2023 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P20A5 stored in the powertrain control module (PCM). This may be due to the software in the glow dosing module (GDM) and does not affect vehicle operation. Due to on-board diagnostic (OBD) functionality, the GDM may be referred to as the secondary OBD control module (SOBDMC) in the Ford Diagnosis and Repair System (FDRS) scan tool.
SSM 514972023-04-06. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2023 F-Super Duty vehicles may set diagnostic trouble codes (DTCS) U3035 and/or U3036 in the powertrain control module (PCM) during a diagnostic self-test. These DTCS set when the PCM detects an authentication failure after key initialization (U3035) and/or while the PCM continues to monitor DTC (U3036) during the transition of the controller area network (CAN) bus entering sleep mode. U3035 and/or U3036 should be ignored if: no other DTCs are present in the PCM, the malfunction indicator lamp (MIL) is not illuminated while the engine is running, and no drivability concerns are present. No further service action is required.
