Emissions C2622
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
This owner notification letter informs owners that Cummins Inc. has launched a campaign that may affect their X15 engine(s). The subject engines may not be meeting certain aftertreatment and on-board diagnostic (OBD) performance requirements, specifically that the OBD system may be unable to detect a fault in the Selective Catalytic Reduction Conversion Efficiency monitor before NOx emissions exceed the emissions limit. As a result, NOx emissions may exceed prescribed standards.
