To whom it may concern,

Excellance received notification from Weldon of the recall on the Hercules nodes in May of 2022. Excellance had one unit here in production that had this issue and it was quickly resolved when Weldon got the part in to us. The other 2 units that we had affected were repaired by the Dealer about a month later when Weldon got the replacement parts to them. All 3 of the units we had affected by this recall has been taken care of. No owner notification is required for this recall.

If anyone has any questions or concerns, please feel free to contact me.

Thank you,

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.
