*** Important Safety Recall *** NHTSA Recall No. 22V780 Weldon Safety Recall Campaign 22E-037 October 19, 2022 Independence, MO 64050 This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Weldon, Division of Akron Brass found that a defect which relates to motor vehicle safety exists in the V-mux Hercules HC 1.5 Nodes that were originally installed in the following vehicles. VIN: – (Squad) VIN: – (Pumper) WHAT WAS THE PROBLEM: Weldon found that the affected Nodes contain a termination resistor installed on the node circuit board instead of the termination resistor being installed only within the electrical harness. If the vehicle network design has not accounted for this additional resistor, it may reduce the bus resistance below the defined tolerance levels and may lead to a loss of data on the CAN network. Installations with multiple nodes are more likely to experience the condition. WHAT ARE WE DOING ABOUT THE PROBLEM? Weldon released safety recall 22E-037 to correct this condition by which Weldon provided replacement units to us. We removed the affected nodes from these two trucks that are identified above and installed the replacement nodes that Weldon provided. The remedy component has the additional termination resistor removed from the circuit board. WHAT SHOULD YOU DO? fire department should do nothing at this time. These repairs were completed before these trucks were placed in service by the department and were done completely free of charge. WHO SHOULD YOU CONTACT IF YOU HAVE FURTHER QUESTIONS OR CONCERNS? If you have questions or concerns about this recall, please contact us at 573-346-8387. If you have a complaint relative to this recall, you may report it to the following: Administrator National Highway Traffic Safety Administration 1200 New Jersey Avenue, SE Washington, DC 20590 Weldon and Precision Fire Apparatus took this action in the interest of safety and satisfaction with our products. We apologize for any inconvenience. Sincerely, Precision Fire Apparatus

There were four affected nodes. These affected nodes were identified as being installed on these two trucks below. Production Dates : JUL 30, 2021 – OCT 26, 2021 VIN Range 1 : Begin : 4S9CT2D99MC560506 End : 4S9CT2D99MC560506 ✔ Not sequential VIN Range 2 : Begin : 4S9CT2D93MC560405 End : 4S9CT2D93MC560405 Not sequential Description of Defect : Description of the Defect : Weldon, a division of Akron Brass Company, produces Node, an electrical multiplex module, under both a private label to a single customer as well as to multiple OEMs for installation in emergency vehicles. In the affected products, the Node contains a termination resistor installed on the node circuit board instead of the termination resistor being installed only within the electrical harness. If the vehicle network design has not accounted for this additional resistor, it may reduce the bus resistance below the defined tolerance levels and may lead to a loss of data on the CAN network. Installations with multiple nodes are more likely to experience the condition. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the bus resistence is reduced, the CAN network connection could faill which may interrupt the transfer of data on this connection. If the CAN network connection is interrupted or fails and depending on how the vehicle’s electrical systems are designed, it may impact the operation of various Part 573 Safety Recall Report 22V-780 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 electrical loads controlled by the Node, including vehicle lighting, which may increase the risk of a crash. Description of the Cause : Per Weldon – Due to a bill of material error, a resistor installed on the printed circuit board was inadvertently included Identification of Any Warning that can Occur : None per Weldon Involved Components : Component Name 1 : V-mux Hercules HC Node 1.5 Component Description : Multiplex Input / Output Node for Weldon V-mux compatible systems Component Part Number : 6060-1000-00, Supplier Identification : Component Manufacturer Name : Weldon Division of Akron Brass Address : 3656 Paragon Drive Columbus Ohio 43228 Country : United States Chronology : Per Weldon – On April 29, 2022, Weldon was contacted by an OEM that described an issue with the CAN connection when installing the Node. Weldon was able to isolate the issue to the inclusion of the additional termination resistor on the circuit board. Weldon stopped the shipment of additional units. On May 2, 2022, Weldon reviewed the technical details affecting the Node to confirm the issue, considered whether the same issue impacts any similar products and decided to conduct a safety recall. On May 3, 2022, Weldon determined a recent shipment of a variation of the Node sold under a private label and to a single customer was also impacted. Weldon confirmed with the customer these units had never been installed in a vehicle and remained in the customer’s inventory. Weldon secured all of the affected products from the customer’s inventory and on May 4, 2022 reworked those units to remove the additional resistor. Part 573 Safety Recall Report 22V-780 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : We received four replacement nodes from Weldon. We removed the two affected nodes from each of the two trucks and installed the corrected replacement nodes that we were provided from Weldon. How Remedy Component Differs from Recalled Component : Per Weldon – the remedy component will have the additional termination resistor removed from the circuit board. Identify How/When Recall Condition was Corrected in Production : Per Weldon – Existing inventory at Weldon was isolated and shipments placed on hold on 4/29/2022, the same day the potential issue was first reported to Weldon. Any affected product in Weldon’s inventory will be reworked and a new part number issued.
