What's wrong?
The i4G Vivtech Display in these 2020 Horton Type Iii and Type I ambulances is the control panel for electrical functions tied to the ambulance body. It lets the crew operate equipment through the display instead of separate switches. When the display is working, the processor inside the panel reads the crew's input and sends commands to the connected systems.
On affected ambulances, the display processor is running near the upper limit of its power supply range. That condition leaves the processor prone to locking up or stalling. Once it locks up, items controlled through the panel stop responding, and the processor has to be reset by turning power off and back on.
There is no warning sign before failure. The display can stop functioning suddenly, so a crew member loses control of panel-operated items at the time the processor stalls.

What should I do?

- Contact a franchised Horton dealer to schedule the free i4G Vivtech display inspection and repair that fixes the control-panel failure.
- Reference recall number 20V745 when you call, and ask whether the front display, rear display, or both displays need inspection by serial number.
- Bring the recall notice from Horton if you have it; the dealer repair is free.

What happens at the repair
At the dealer, a Horton technician checks the i4G Vivtech display serial number and inspects the rear or front control display covered by this recall. If the display is within the affected serial number range, the dealer repairs it free of charge. The work is meant to restore proper control-panel operation for equipment that depends on the display, so tell the service desk about any display or control-panel functions that stopped working before your appointment.
