# Service bulletin 20\-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

The style 9333 and 9335 valve controller display is used to control water valves on a fire truck. In some instances, the controller was found to momentarily lose communications connection with the associated valve. This software update eliminates this possibility.
