What's wrong?
The Weldon V-Mux Vista IV Standard LCD display in the 2012 Sutphen SP70 is the screen and control panel for emergency vehicle lighting and HVAC functions. In normal use, it gives the operator a working interface for those systems, so lighting and climate controls respond from the display instead of separate switches.
On the recalled vehicle, the display is vulnerable to low voltage spikes tied to the electrical installation. Those voltage changes interfere with the display electronics. When that happens, the screen can lock up or stop working, leaving the lighting and HVAC controls unavailable from that panel.
There is no warning sign before failure. The first sign is the display freezing, locking up, or becoming non-functional while the vehicle is in use.

What's the safety risk?
A locked or nonfunctional LCD display can slow emergency response work and increase the risk of injury. Treat a locked or failed display as a service issue, because emergency crews rely on clear vehicle information during a response. Repair is free at any franchised Sutphen dealer.
