Service bulletin FSB237-020

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

VOLVO VN, VHD, VAH, and VT trucks built from 2009 to 2017 and equipped with 11, 13, and 16 liter engines (EM-USA10, EM-USA14, and EM-USA17), will require a new torque specification for the Unit Injector Yoke Hold-Down Bolt. Effective immediately, the torque value in step 3 has changed to 25 +5/-0 Nm (18 +4/-0 ft-lb).

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