Recall 10V003000: 2009 Emergency One Cyclone II, 2009 Emergency One Typhoon

The problem

E-one is recalling certain model year 2009 typhoon and cyclone ii fire trucks equipped with cummins isc cm2150 and isl cm2150 model diesel engines. The trucks may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures to discharge from the fire truck. Due to 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.

The risk

This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or persons adjacent to the tailpipe, or a fire.

The fix

E-one is working with cummins to repair the engines free of charge. Please see cummins' defect report 09e-046. Owners may contact cummins at 1-800-diesels (1-800-343-7357).
