Service bulletin SSM 47949

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

SSM 47949 - 2017-2019 F-Super Duty - LED Headlamps - DTC U2100 Some 2017-2019 F-Super Duty vehicles may exhibit a diagnostic trouble code (DTC) U2100 in the body control module B (BCMB). Vehicles equipped with factory LED headlamps do not require a BCMB to operate the headlamps. If equipped with LED headlamps, the U2100 DTC should be ignored. It will not affect the performance of the LED headlamps or other systems that control exterior and interior lighting. Do not attempt any repairs.
