What's wrong?
The V-mux Hercules HC Node 1.5 on 2021-2023 Spartan Fire Metrostar, FC-94, and Gladiator fire trucks is a multiplex input and output node. In plain terms, it is an electrical control module that lets parts of the truck share commands over the CAN network, the truck's internal communication line. That network helps lighting and other electrical functions receive the right signals.
On affected trucks, an extra termination resistor was installed on the printed circuit board because of a bill of material error. A printed circuit board is the small board inside the module that connects its electronic parts. The added resistor changes how the module communicates, which disrupts CAN network traffic and causes vehicle lighting to fail.
The remedy removes the extra termination resistor from the circuit board so the node matches the intended design. There is no warning sign before failure. If the lighting stops responding or acts incorrectly, treat the truck as affected until Spartan Fire confirms the recall repair is complete.

What's the safety risk?
Inoperable vehicle lighting can make the vehicle harder to see and reduce the driver's visibility, increasing crash risk. There is no warning sign before failure, so treat any failed lighting as a reason to schedule service and limit low-light driving until repaired. Repair will be free at any franchised Spartan Fire dealer once available.
