Summary
Some 2020 F-Super Duty vehicles equipped with an aftermarket bed may exhibit inoperative trailer lights on one or both sides of trailer after performing the FDRS Turn Signal Lamp Configuration application on the vehicle. Version 12 of this application is now available on the FDRS to address this trailer lighting condition. Make sure to download version 12 or later of the FDRS Turn Signal Lamp Configuration and follow the on screen prompts to configure the aftermarket bed. Verify the trailer lighting is operating correctly once complete. If the Turn Signal Lamp Configuration application was previously run on the vehicle, make sure to run the BCM Reset option before re-running the application.
