Service bulletin 20-01
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 product is a controller which operates a valve on a fire truck. If a flow sensor is mounted near the valve motor, there is a possibility of the flow display on the controller momentarily showing flow values whenever the valve is commanded to open or close. This is due to inductive coupling between the magnetic field of the motor and the flow sensor. To prevent this, there is a configurable option in the installation/set-up menu which is used to eliminate this. This bulletin clarifies how to utilize this setting if this condition is observed. There is no impact on function of the valve.
