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

Per Daimler Truck North America's Campaign Number "SF644A\-C": On certain vehicles and under certain circumstances, the tire pressure monitoring system \(TPMS\) may display incorrect information such as maximum temperature and tire pressure, and/or a message that the tires are under or over\-inflated. The TPMS controller will be updated with new software, and certain units will require a longer antenna\-mounting bracket to extend the rear antenna downward.
