Some 2021 F-Super Duty vehicles equipped with a 6.7L engine and built on 07-Jul-2021 and through 11-Jul-2021 may not properly complete powertrain control module (PCM) reprogramming or programmable module installation (PMI) resulting with diagnostic trouble code (DTC) U029E. PCM reprogramming and/or PMI for vehicles in this build date range is not recommended at this time. Monitor OASIS broadcast messages for updates. A fix is expected before the end of February 2022.
