What's wrong?
The Vista IV display in the 2021 Osage Super Warrior is the control screen for emergency vehicle lighting and HVAC functions. It is the panel an operator uses to see system status and press on-screen controls, so the lighting and climate controls depend on the screen starting up and responding normally.
On the affected vehicle, the display does not restart correctly after voltage drops below 9 volts. The root problem traces to an obsolete component in the display hardware and to varying electrical installations. When the voltage drop happens, the LCD screen can lock up, go blank, or stop accepting button inputs. Cycling power resets the unit and restores normal operation until the affected unit is replaced.
There is no warning sign before failure. The first thing an operator notices is the display locking up, going blank, or not responding when controls are pressed.
