27855 James Chapel Road • P.O. Box 249 • Holden, Louisiana 70744 www.ferrarafire.com • [email protected] Direct: 225‐567‐7100 • Toll Free: 800‐443‐9006 • Fax: 225‐567‐5260 July 15, 2022 IMPORTANT SAFETY RECALL: 22V-409 V-MUX Hercules HC Node 1.5 This notice applies to your vehicle VIN: X UNIT: 1xxxxx This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Ferrara has decided that a defect which relates to motor vehicle safety exists in certain models of the following emergency vehicles manufactured March 29, 2022 to May 10, 2022, equipped with V-MUX Hercules HC Node 1.5: Ferrara – 2022 Custom Inferno, Igniter WHY IS A RECALL BEING CONDUCTED? 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. If the bus resistance is reduced, the CAN network connection could fail 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 electrical loads controlled by the Node, including vehicle lighting, which may increase the risk of a crash. No warning will precede the failure. Due to a bill of material error, a resistor was installed in error on the printed circuit board. The affected item is the V-MUX Hercules HC Node 1.5. WHAT ARE WE DOING ABOUT THE PROBLEM? Vehicles subject to this recall are to be inspected and repaired by a Ferrara certified Dealer. Ferrara will compensate the Dealer for installing the new Nodes which are provided free of charge if it has not already been replaced during normal maintenance. The estimated time for the repair varies by the truck model, the number of Nodes in the truck and the location of the Node. The average repair time per Node will be from 1 hour to 6 hours per Node depending on the afore mentioned variables. WHAT SHOULD YOU DO? If you receive this notification, please contact your Ferrara Dealer or Ferrara at 1-800-443-9006 to schedule an appointment to have the repairs performed. INCLUDED WITH THIS LETTER IS AN OWNER RESPONSE CARD THAT MUST BE FILLED OUT AND RETURNED TO E-ONE IN ORDER TO BE REIMBURSED. Please have your Truck VIN available.

Description of the Cause : Due to a bill of material error, a resistor was installed in error on the printed circuit board. Identification of Any Warning that can Occur : NONE 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 : Refer to NHTSA Recall 22E-037 below for Weldon’s chronology. 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. On May 16, 2022, Ferrara Fire received communication from Weldon about recall 22E-037 for their V-mux Hercules HC Node 1.5. On May XX, 2022, it was agreed that Ferrara Fire should file a Part 573 May 16, 2022 – Escalated the issue to REV Group Management. Part 573 Safety Recall Report 22V-409 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 May XX, 2022 – REV’s senior leadership approved a voluntary recall for this issue.
