ELECTRICAL SYSTEM:IGNITION:MODULE
Cummins Inc. (Cummins) is recalling certain ISB6.7, ISL9, ISX12 and ISX15 engines. The affected engines have an Engine Control Module (ECM) that may short circuit and blow a fuse resulting in the engine stalling without warning.
Risk: An engine that stalls without warning increases the risk of a crash.

ENGINE AND ENGINE COOLING:ENGINE:DIESEL
Cummins is recalling certain model ISB6.7 diesel engines manufactured from February 16, 2010, through May 4, 2012, equipped with fan pulley Part Number 3914462 and installed on certain Thomas Built Buses, Inc. school buses. The subject fan pulley is part of the accessory drive system on the front of the engine. This system is used to drive such components as the refrigerant compressors, the radiator fan, and the engine water pump. The web of the pulley can fatigue over time, causing the pulley to fail.
Risk: If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. This may result in exceeding temperature limits, potentially disabling the school bus. If the school bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury.

ENGINE AND ENGINE COOLING
CUMMINS IS RECALLING CERTAIN ISB6.7, ISC8.3, ISL9, ISX11.9, AND ISX15 ENGINES SHIPPED FROM SEPTEMBER 2010 THROUGH DECEMBER 2010 TO VARIOUS VEHICLE MANUFACTURERS. THESE ENGINES WERE INSTALLED IN RECREATIONAL VEHICLES, EMERGENCY VEHICLES, BUSES, AND CERTAIN TRUCK APPLICATIONS. THE V-BAND CLAMP ASSEMBLY, PART NUMBERS Q187684, Q187685, AND Q187686, USED TO CONNECT THE INLET AND OUTLET CONE SECTIONS TO THE DIESEL OXIDATION CATALYST (DOC)/DIESEL PARTICULATE FILTER (DPF) INCLUDE A T-BOLT WHICH CAN FRACTURE AND FAIL WHEN SUBJECTED TO STRESS OR LOAD. A FRACTURE OR FAILURE OF THE T-BOLT MAY CAUSE THE CLAMP TO LOOSEN AND THE INLET OR OUTLET SECTIONS ATTACHED TO THE DOC/DPF HOUSING TO DISCONNECT.
Risk: IF THE INLET OR OUTLET SECTIONS DISCONNECT, HOT EXHAUST GASES CAN VENT PRIOR TO EXITING THE TAILPIPE, CREATING THE RISK OF COMBUSTION AND A FIRE. IF BOTH CLAMPS FAIL, THERE IS A RISK IN SOME APPLICATIONS THAT THE DOC/DPF HOUSING MAY DETACH COMPLETELY, CREATING A ROAD HAZARD.
