Service bulletin PIP6101
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
The document makes technicians aware of a valvetrain tick noise that is created by one or more soft lifters. The soft lifter concern is due to manufacturing debris within the lifter when it was manufactured. The document instructs the technician to replace the soft lifter(s) and the rocker arm it operates.
