Service bulletin AFC13904

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

ECM and Body controller software update to provide engine protection against an increase in engine RPM while vehicle is idling (only in a parked state or if vehicle is not moving) and to prevent cruise control drop out; only models equipped with MaxxForce 13 engine. Retired

Listing a model year does not mean every vehicle of it is concerned: the document says which.
