Service bulletin SU22-02
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
This document provides information on the cluster software improvement to address symptoms of acceptable parasitic battery loss attributed to CAN Devices not going to sleep. This symptom is occasionally accompanied by the cluster flashing on/off on an approximately 3-minute frequency. Blue Bird and Ametek have developed a software to alleviate this concern.
