2022 Pierce F550, Pierce M2-106, Pierce M2-112: Electrical System recall

NHTSA campaign 22V596000 · 10 units potentially affected · filed Aug 8, 2022

What's wrong

Pierce Manufacturing (Pierce) 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.

Why it matters

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

The fix

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

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.
