WASHINGTON, D.C. --- Cummins Inc. is recalling 912 diesel engines installed as original equipment in various emergency vehicles.
According to the National Highway Traffic Safety Administration, the vehicles affected by the recall 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. 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 is not.
This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, and also increasing the risk of a fire, the NHTSA said.
To resolve the problem, each vehicle manufacturer that included these engines as original equipment will file a defect report and remedy plan for their vehicles.
