Service bulletin SSM 48907

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.

NHTSA's summary

Some 2020 F-53 Motorhome/F-59 Commercial Stripped Chassis, 2021 F-650/F-750/E-series vehicles built before 31-Mar-2020 may have been equipped with customer configurable daytime running lamps (DRL). The ability to disable customer configuration of DRL is now available in IDS version 118.01 or higher if the customer desires to keep the DRL always enabled. Once this optional procedure is complete, DRL will no longer be configurable and permanently set to on. Ensure the DRL feature is turned on in the IPC prior to performing this process. There is no way to return the feature to customer configurable in the instrument panel cluster (IPC) after this process is completed. Vehicles not equipped with DRL or built after 31-Mar-2020 are not eligible for this procedure under warranty. Do not submit claims on those vehicles.
