To test the diesel oxidation catalyst, use INSITE electronic service tool to perform the Aftertreatment Diesel Particulate Filter Regeneration Test. The efficiency of the diesel oxidation catalyst will be determined. If a malfunction in the catalyst system is detected, fault codes will become active during the test. Follow the appropriate fault code troubleshooting tree. … Read More »
Due to number of different exhaust aftertreatment applications, this procedure is generic. Illustrations within this procedure will not represent all applications. The exhaust aftertreatment system is composed of four sections: 1 Inlet 2 Aftertreatment diesel oxidation catalyst 3 Aftertreatment diesel particulate filter 4 Outlet NOTE: In some applications the aftertreatment diesel oxidation catalyst can be… Read More »
If the aftertreatment diesel particulate filter was cleaned or replaced due to Fault Code 1922, it will be necessary to reset the stored soot load in the engine’s ECM. This can be performed by the following: • Use INSITE electronic service tool to perform the Aftertreatment Maintenance Reset Procedure under the … Read More »
If the aftertreatment diesel particulate filter is being removed for an ash cleaning or soot cleaning maintenance interval, the aftertreatment diesel particulate filter will need to be removed and cleaned with a cleaning tool approved by Cummins Inc. consult service tool instructions, Bulletins 3400284 and 3400253, for information regarding parts and operation of Cummins Inc.… Read More »
• Install the new gaskets on the inlet and outlet of the aftertreatment diesel particulate filter canister. NOTE: In some applications, a locating tab is integrated into the gasket retaining ring. The locating tab prevents the jointed aftertreatment diesel oxidation catalyst- aftertreatment diesel particulate filter from being installed backward and restricts the rotational orientation at… Read More »
Three-bolt Connection • Install the exhaust gas temperature sensor to the aftertreatment diesel oxidation catalyst section. Use the following procedure in the Troubleshooting and Repair Manual, CM2150 Electronic Control System, ISS, ISC, ISL, ISLe, ISDe and QSB3.3 Engines, Bulletin 4021570. Refer to Procedure 019-013 in Section 19. NOTE: The… Read More »
NOTE: The aftertreatment diesel particulate filter relies on gas flow through the walls to collect soot. To accomplish gas flow through the walls of the aftertreatment diesel particulate filter, every other cell on the face of the aftertreatment diesel particulate filter is plugged with a ceramic material. Therefore, it is not possible to see light… Read More »
Three-bolt Connection • Remove the exhaust gas temperature sensor from the aftertreatment diesel oxidation catalyst section, if necessary. Use the following procedure in the Troubleshooting and Repair Manual, CM2150 Electronic Control System, ISB, ISC, ISL, ISLe, ISDe and QSB3.3 Engines, Bulletin 4021570. Refer to Procedure 019-013 in Section 19.
V-Band Clamp Connection • Mark the direction of exhaust flow to aid in assembly. • Draw an orientation reference line across each of the V-band clamps, aftertreatment canister sections, and connection points to the tailpipe. This aids in the alignment of sections and V-band clamps to… Read More »
