# Service bulletin 43\-064

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

Information only: Peterbilt has determined that certain Models 567 and 579 vehicles built between July 06, 2012 and March 27, 2020 with the PACCAR MX\-13 Engine may experience an overspeed lamp illuminating during a smoke opacity test. If the lamp illuminates, it is not an indication of a problem with the vehicle but may cause the inspector to not allow the vehicle to operate in California.
