Service bulletin T2490
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 is being issued to address certain Daimler (Freightliner, Thomas Built Bus, Western Star) vehicles with DEF header sensor failures in which DEF header replacement parts are not available. Due to DEF header part shortages, an ECM calibration is being released that reduces inducement levels to allow for continued operation of the vehicle until DEF header parts become available for a final repair.
