# Service bulletin SC\-19\-58

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.

Voltage sags are causing the datalogger to reset, losing data used for monitoring and servicing the vehicles. Proterra issued this service bulletin to add a diode that will prevent voltage sags and loss of data.
