Service bulletin SSM 50475

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 2021 Mustang Mach-E vehicles may show a Ford Diagnosis and Repair System (FDRS) anti-lock brake system (ABS) module software update available after a successful coordinated PCM software update. If the coordinated PCM software update on the PCM, BECM, SOBDMC and ABS completed, the ABS software update app still being present in FDRS can be disregarded. No further programming for this condition is required.
