Electronic fault codes active or high counts of inactive fault codes
View and troubleshoot the fault codes with INSITETM electronic service tool. Refer to Section
TF for active fault code troubleshooting. Refer to the following procedure in the the ISB, ISC, ISL,
ISLe, ISDe, and QSB3.3, CM2150 Electronic Control System, Troubleshooting and Repair Manual, Bulletin 4021570 for inactive fault code troubleshooting. Refer to Procedure 019-362 in Section 19.
Stationary (Parked) Regeneration stops after a short period of time
Verify that all of the conditions that allow a stationary (parked) regeneration to activate are still
valid. Refer to the Stationary Regeneration- Will Not Activate symptom tree.
Stationary (Parked) Regeneration not allowed to run to completion
Allow the stationary (parked) regeneration to run until completion, which can take up to 2.5 hours.
Refer to Procedure Procedure 014-013 in Section 14.
Exhaust leaks in the OEM exhaust piping leading to the aftertreatment system or leaks in the aftertreatment system
Inspect the OEM exhaust piping and the aftertreatment system for exhaust leaks. Refer to
Procedure Procedure 010-024 in Section 10
Aftertreatment Gas Temperature Sensors are not functioning properly
Monitor the aftertreatment gas temperature sensor values with INSITETU electronic service tool during the stationary (parked) regeneration. Refer to Procedure Procedure 011-056 in Section 11.
EGR valve is not functioning properly
Verity that the EGR valve is closed during the stationary (parked) regeneration. Refer to
Procedure 011-022 in Section 11.
Turbocharger is not functioning properly
Use INSITEru electronic service tool to verify that the turbocharger actuator position is maintained at 89 percent closed or higher during the stationary (parked) regeneration. If the turbocharger actuator position does not maintain 89 percent closed or higher, verify that the turbocharger sector gear has full travel. Refer to Procedure Procedure 010-134 in Section 10.
Aftertreatment System is damaged
Check for progressive damage to the aftertreatment system. Refer to Procedure Procedure 014-013 in Section 14.
Electronic control module (ECM) calibration is malfunctioning
Verify that the electronic control module (ECM) calibration is correct. Check the calibration revision history for applicable fixes to the calibration stored in the ECM. Refer to the calibration history spreadsheet ecm_calibration_rev_history.xlson QuickServeru Online Internet Website or the INCALru calibration CD. Compare the calibration stored in the ECM with the engine rating and the Control Parts List (CPL), Bulletin 4021326 or 4021327. If necessary, calibrate the ECM. Refer to Procedure 019-032 in Section 19 of the ISB, ISC, ISL, ISLe, ISDe, and QSB3.3, CM2150 Electronic Control System, Troubleshooting and Repair Manual, Bulletin 4021570.
