SEOCONTENT-START

IMPORTANT SAFETY RECALL NHTSA RECALL NO. 22V-853 VIN: Dear Midwest Fire Customer: This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Midwest Fire has decided that a defect, which relates to motor vehicle safety, exists in certain model year 2022-2023 All-Poly Series fire trucks manufactured October 1, 2021 to October 31, 2022. The affected vehicles are equipped with a split-shaft transmission and the Class1 Es-Key multiplex system. The Es-Key multiplex system needs to be reprogrammed from M0 to M5 to allow for the pump to shift from road to pump and pump to road modes. Without this update, you may experience pump shifting issues. The inability to shift modes may delay emergency response, increasing the risk of injury. Midwest Fire has initiated a recall to remedy the noncompliance free of charge. Please contact Midwest Fire to schedule the repair. Midwest Fire will send a USB to USB cable to do the reprogramming of the Class1 multiplex system at no charge to the customer. The customer will need to go to http://firmware.class1.com/login.aspx?ReturnUrl=%2f, create an account with a username and password and then download the ES-KeyPro II Read Only Version 1.0.93 program and save to their desktop. Customer will then contact Midwest Fire who will login remotely and install the new program for them. This will be done at no charge to the affected customers. If you believe there is a failure to remedy this defect without charge and within a reasonable time, you may submit a written complaint to the Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue, SE, Washington, D.C. 20590; or call the toll-free Vehicle Safety Hotline at 1-888-327-4236 (TYY: 1-800-424-9153); or go to http://www.safercar.gov.
