Service bulletin SD-08-12046
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.

As a module, they provide heavy vehicles with an integrated vehicle air dryer, purge reservoir, governor, and a number of the charging valve components in a complete assembly. These components have been designed as an integrated air supply system.
