NHTSA recall 09V425000
Engine and engine cooling
International 7600
The defect
Navistar IS recalling certain model year 2008 and 2010 emergency vehicles manufactured between june 12, 2007 and june 24, 2009, equipped with cummins isb cm2150, isc cm2150, isl cm2150, ism cm876, and isx cm871 model diesel engines. the vehicles 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. 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 a fire.
The remedy
Cummins IS conducting this campaign and will provide the remedy free of charge. please see cummins defect report 09e-046. owners may contact cummins at 1-800-343-7357.
