TSB: Ford Glow Module

Some 2024 Ford F-Super Duty vehicles built on or before October 3, 2024 and equipped with a 6.7L diesel engine may exhibit a MIL on with DTC P20A5 stored in the PCM. This may be due to the software in the glow dosing module (GDM) and does not affect operation. Due to OBD functionality, the GDM may be referred to as the SOBDMC in the FDRS scan tool. To correct the condition, reprogram the SOBDMC using the latest software level.
