The problem
Daimler Trucks North America LLC (Daimler) is recalling certain model year 2009-2015 Thomas Built Saf-T-Liner HDX school buses manufactured February 25, 2008, through February 11, 2014, equipped with Cummins Westport Model ISL G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
The risk
The sensor malfunction could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
What to do
Cummins and Cummins Westport will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Customers may contact Daimler at 1-800-385-4357 or Cummins Inc. at 1-800-343-7357. Daimler's number for this recall is FL-660.
