WASHINGTON, D.C. --- HME Inc. is recalling 29 MY 2009 1871 Fire Trucks built on Cummins' diesel engine, NHTSA reported.
The vehicles may be designed with a hard-wired, dash-mounted switch that enables the vehicle operator to inhibit after-treatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. But because of an issue with the logic in the ECM software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it's not.
This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire.
HME is working with Cummins to repair the engines free of charge. Owners can contact Cummins at (800) 343-7357.
