ISM, ISMe, and QSM11 – Stationary Regeneration – Will Not Complete

Symptom Tree  t149

This is symptom tree t149
Cause Correction

This tree is to be used when the engine speed changes after the stationary (parked) regeneration has been started and either stops after a short period of time, or continues for an excessive period of time. If the engine speed does not increase when the stationary (parked) regeneration is started, refer to the Stationary Regeneration – Will Not Activate TS tree (t146).

Electronic fault codes active or high counts of inactive fault codes

View and troubleshoot the fault codes with INSITE™ electronic service tool. Refer to Section TF for active and inactive fault code troubleshooting, Procedure 019-362 in Section 19 of the ISX and ISM CM871 and CM876 Electronic Control System, Troubleshooting and Repair Manual, Bulletin 4021560.

 

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 014-013 in Section 14. NOTE: The 2.5 hours is the maximum time that a regeneration will take to complete. If the Diesel Oxidation Catalyst temperature is not at or above 316°C [600°F] and the aftertreatment injector has not turned on within 1 hour, abort the regeneration and continue through this tree.

 

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 010-024 in Section 10
.

 

Aftertreatment Gas Temperature Sensors are not functioning properly

Monitor the aftertreatment gas temperature sensor values with INSITE™ electronic service tool during the stationary (parked) regeneration. Refer to
Procedure 011-056 in Section 11.

 

Fuel metering actuators are not functioning properly

Monitor the engine percent load value with INSITE™ electronic service tool during the stationary (parked) regeneration. If this value stays consistently above 8% the metering actuators are over fueling and need to be replaced. Refer to Procedure 019-110 in Section 19 of the ISX and ISM CM871 and CM876 Electronic Control System, Troubleshooting and Repair Manual, Bulletin 4021560.

 

EGR valve is not functioning properly

Verify 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 INSITE™ 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 010-134 in Section 10.

 

Aftertreatment System is damaged

Check for progressive damage to the aftertreatment system. Refer to
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 Click here to see ecm_calibration_rev_history.xls

on QuickServe™ Online Internet Website or the INCAL™ 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 ISX and ISM CM871 and CM876 Electronic Control System, Troubleshooting and Repair Manual, Bulletin 4021560.
