Service bulletin T2083A
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 Temporary Repair Practice authorizes certified repair locations to upfit certain ISB, ISC, and ISL CM2250 engines with an improved Selective Catalytic Reduction (SCR) Catalyst. The engine must show open for this field action, experience a complaint or symptom in which troubleshooting results in the replacement of the SCR, and the SCR part number must match the Affected Part Number list. This is an update to a previously submitted communication.

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