Service bulletin SP14-320B
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
On the vehicles affected by this bulletin, perform a software update of ECM and ACM to modify the dosing strategy. The software will also improve urea dosing valve behavior at shutdown and key-on. As an additional improvement, replace the urea dosing valve by an improved design and modify coolant hose routing to the dozer valve to provide additional cooling at engine shutdown.
