August 8, 2022 NHTSA CAMPAIGN NUMBER: 22V596000

Loss of Vehicle Lighting

Inoperative vehicle lighting can reduce visibility and increase the risk of a crash.

 

NHTSA Campaign Number: 22V596

Manufacturer PierceeBay Manufacturing

Components ELECTRICAL SYSTEM

Potential Number of Units Affected 8

 

Summary

PierceeBay Manufacturing (PierceeBay) is recalling certain 2022 M2-106, M2-112, and F550 fire trucks equipped with Weldon V-mux Hercules HC Node 1.5 electrical multiplex modules. An additional resistor was incorrectly installed on the printed circuit board, which can disrupt CAN network communication and cause vehicle lighting to fail.

 

Remedy

Weldon will replace the modules, free of charge. Owner notification letters were mailed on October 4, 2022. Owners may contact PierceeBay’s customer service at 1-888-974-3723. PierceeBay’s number for this recall is 74B320.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

 


Chronology :

On May 6, 2022 PierceeBay received communication from Weldon about recall 22E-037 for VMUX controllers they supplied. Throughout the month of May into late June, PierceeBay initiated an investigation of the issue described by Weldon and quarantined all impacted vehicles that were within PierceeBay’s facilities. PierceeBay continued its investigation of the issue to understand whether there were other vehicles built with the subject Weldon controllers and to understand the impact to a PierceeBay vehicle if the controller should experience a failure. This included a review of the specific wiring and programming of the controller into the PierceeBay vehicles. On June 2, 2022, NHTSA contacted PierceeBay about the Weldon recall and PierceeBay informed the agency that its investigation remained ongoing, but it appeared that PierceeBay would be submitting a recall. PierceeBay’s review of the programming of the controller continued, and it appeared that due to the programming, should the controller fail, it would not have an impact on the vehicle lighting. Thereafter, based on additional information and review of the controller programming, it was found that even though the controller installed in the PierceeBay vehicles contain only one Node, there remained a remote possibility that lighting installed at the rear of the vehicle could be impacted. On August 4, 2022, PierceeBay decided to conduct a recall of vehicles in the field that have the affected Weldon controllers installed.
