What's wrong?
The V-mux Hercules HC Node 1.5 on the 2021 Spartan Fire Metrostar is an electrical multiplex module. It acts like a traffic controller for the truck's V-mux system, taking input and output signals and passing messages across the CAN network, the wiring communication system that lets emergency lighting and related electrical controls talk to each other.
On affected Metrostar trucks, the node was built with an extra termination resistor on the printed circuit board. That resistor was included because of a bill of material error. Its presence interferes with CAN network communication, so messages do not move through the system correctly. When that happens, vehicle lighting can fail instead of responding to the controls.
There is no warning sign before failure. Weldon reported no owner-notice symptom, so treat any unexpected loss of emergency lighting or lighting control as a service issue tied to this recall.
Who's affected?
Both listed components trace to the same V-mux Hercules HC Node 1.5, a multiplex input/output node used in the emergency-lighting electrical system.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Inoperative vehicle lighting reduces visibility and increases the risk of a crash, especially when other drivers need to see the vehicle clearly. There is no warning sign before failure, so schedule the recall repair promptly if your VIN is included. Repair is free at any franchised Spartan Fire dealer.
What should I do?
- Check your VIN to confirm your 2021 Spartan Fire Metrostar is included in this recall.
- Contact a franchised Spartan Fire dealer to confirm the free electrical multiplex module replacement has been completed.
- Reference recall number 22V780 when you call so the service desk can find the lighting and CAN network repair.
- Bring the recall notice if you have it, and ask the dealer to document the completed module replacement.
- Avoid operating the vehicle in low visibility until the repair is confirmed and all exterior lighting works normally.
What happens at the repair
Precision Industries already replaced the electrical multiplex modules on both affected Spartan Fire Metrostar vehicles at no charge. The repair addresses the incorrectly built module by replacing the module that controls CAN network communication for vehicle lighting. If you are confirming service history, ask a Spartan Fire dealer or Precision Industries customer service to verify that the recall repair is marked complete for your VIN. Precision Industries has a general reimbursement plan on file. If you paid for a module related repair before the recall work was completed, contact Precision Industries customer service with repair documentation to ask about reimbursement under that plan.

Frequently asked questions
What is recall 22V780?
Recall 22V780 covers 2 2021 Spartan Fire Metrostar emergency vehicles with an electrical multiplex module defect. An incorrectly installed resistor can disrupt CAN network communication and cause vehicle lighting to fail, reducing visibility and increasing crash risk. The modules were replaced free of charge.
What should I do if my 2021 Spartan Fire Metrostar is on this recall?
Check your VIN to confirm whether your specific vehicle is included in recall 22V780. If it is included and your records do not show the module replacement, contact a Spartan Fire service desk or Precision Industries customer service at 1-573-346-8387. Reference recall 22V780 when you call.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Precision Industries replaced the affected electrical multiplex modules free of charge. Both affected vehicles have been repaired under this recall.
What is the safety risk?
The safety risk is failed vehicle lighting. If the lighting stops working, the emergency vehicle becomes harder for others to see, which increases crash risk. Recall 22V780 addresses that risk by replacing the affected electrical multiplex modules.
