IMPORTANT SAFETY RECALL NHTSA RECALL
24E‐006
This notice is sent to you in accordance with the National Traffic and Motor
Vehicle Safety Act. Weldon, a division of Akron Brass Company, has decided that
a defect, which relates to motor vehicle safety, exists in certain V‐MUX Hercules
HC I/O Nodes, Weldon Part Number 6060‐2010‐00.
In the affected products, short circuit protection may not function properly. In
the case of a short circuit failure in the vehicle wiring or the connected device, overheating of the wiring or the
connected device may occur, and depending on how the product is installed in the vehicle, this could increase the risk
of a vehicle fire. This is the same issue identified on Weldon 8 x 16 nodes that are covered under previous recall 23E‐
084. While you may have a vehicle covered by both recalls, the same software update fixes all the nodes on the vehicle.
You are receiving this notice because your vehicle manufacturer records indicate you have received a vehicle that
contains an affected unit or units. Vehicles equipped with these devices need a firmware or software update. You
may also receive a notice from the vehicle manufacturer.
All the affected nodes installed in your vehicle can be updated with one connection to the V‐MUX network, without
accessing the individual nodes. The design files and functionality are not affected. A Weldon service app and the
downloader kit is utilized to make the firmware update, free of charge. This update is estimated to take an average of
5‐10 minutes and can be completed when the vehicle is in PM without other changes.
Weldon will provide the update application to authorized service providers to install the firmware update along with
instructions.
Please contact Weldon Customer Service fsg‐[email protected] and reference this recall number and provide your
agency name and mailing address to obtain the remedy at no cost to you.
Please note that it is a violation of Federal Law to deliver a new motor vehicle or any item of motor vehicle
equipment which is subject to a recall until the remedy has been performed.
If you believe there is a failure to remedy this defect without charge to the end user/owner of the vehicle and within
a reasonable period of time, you may submit a written complaint to the Administrator, NHTSA, 1200 New Jersey
Ave, SE, Washington, DC 20590, or call the Vehicle Safety Hotline 1‐888‐327‐4336 (TTY: 1‐800‐424‐9153) or go to

the latest version available on Akron website (in the same location as the other OS) https://smhttp‐ssl‐
61500.nexcesscdn.net/media/pdf/AllOSFiles20240201.zip or download OS from Akron as you typically would.
Completed vehicles that remain at your facility may have all the affected Hercules HC 1.7 nodes installed updated at
the same time and without accessing the individual nodes or design files. To do this, use the Weldon update utility
app and the downloader kit. This update is estimated to take 5‐10 minutes.
