Truck Heading to the Shop - lovoltage - 04-10-2017
Taking the truck to Mr. Hagg's later this week to correct some things I was not able to correct at home. In addition to what I know needs t be done, what else should we be looking at?
2014 KW T660
516K miles
ISX15 CM2350 (ISX15 450ST)
Was a team truck, bought in 2016 May used for household goods, limited OTR miles running 1/2 to 2/3 GVW. Rarely gross 80k lbs
Issues began at the start of the year, has been in and out of shops since. Found this website, studied the issues and corrected many at home. Shops did some work first, and I did some after spending way too much time and money and still having issues. Found many issues with the shop work.
Fixed so far
- Fuel pump campaign (ceramic plungers issue) (Shop under warranty)
- Aftertreatment system repair of aftertreatment wiring harness (shop)
- Overhead adjustment (shop)
- Aftertreatment system DEF doser injector (shop)
- Aftertreatment system DPF (Shop) (Sept 2015 new installed)
- Turbo and aftertreatment diesel injector (shop) (March 2016, Cummins reman turbo and new VGT actuator. New updated diesel aftreatment injector)
- EGR Tune Up with sensor & small diameter pipe replacement (Self)
- NOX outlet sensor (Self)
Known outstanding issues
- TSB notification from Cummins on a conflict between the engine and aftertreatment calibration files (after 1st shop updated the calibration) (Can post details of the TSB)
- Fault code for regen too often
- Usually 5 regens in under 40 hrs of engine operation
- Regens last for about 20 mins (incomplete regen)
- Intake throttle actuator fails self calibration intermittently at engine start; becomming more frequent and unit has become noisy during operation; Ongoing issue since purchase of truck
- EGR cooler down pipe is leaking small amounts of coolant at block junction seal externally
- Ghost fault code. According to Cummins the fault code does not apply to my ESN
Need to check
- Verify fuel pump warranty work
- Verify overhead setting was done right
- Verify/correct calibration files
The EGR tune up went smoothly, seemed that the ERG plumbing was in better shape than expected. Deposits were evenly coated and no signs of leaking coolant or oil. MPG after last shop went way down. After EGR tune Up, went way up.
- Before issues started 6.5 MPG all day 55 mph or 75 mph
- After shops 5.7 MPG
- After EGR Tune Up, over 7.1 MPG, not usually over 70 mph
Opinions and suggestions on what else we should look at?

Technical Service Bulletin
Subject
Engine Control Module (ECM) Calibration and Aftertreatment Selective Catalytic Reduction (SCR) Catalyst Compatibility
Issue
Engine control module (ECM) calibrations released after June 21, 2013 are only compatible with specific aftertreatment selective catalytic reduction (SCR) catalyst part numbers. Downloading newer versions of an ECM calibration may require the aftertreatment SCR catalyst to be replaced. To determine the appropriate repair direction, use the ISX12/15 CM2350 Calibration Selection Tool. See link provided below.
Verification
Product Affected
ISX12 CM2350 X102
ISX15 CM2350 X101
Use the ISX12/15 CM2350 Calibration Selection Tool below to determine if a replacement SCR catalyst is required following an ECM calibration download or if an alternate ECM calibration is available to address the issue on the subject engine. An alternate ECM calibration that does not require an SCR catalyst replacement may be available.
NOTE: https://quickserve.cummins.com/qs3/portal/service/scr_evaluator/index.html
In addition, check the ECM calibration revisions history on QuickServe Online under My Applications section for the specified ECM base code. See link below.
NOTE: https://quickserve.cummins.com/qs3/portal/ecm/spreadsheet_display.html?header=false
Aftertreatment SCR catalyst compatibility with ECM Calibrations released after June 21, 2013 can be found in Table 1.
Aftertreatment SCR catalysts that are compatible with ECM calibrations released after June 21, 2013 can also be visually identified by dimples in the aftertreatment SCR catalyst heat shield. These dimples go around the circumference of the aftertreatment SCR catalyst heat shield and can be found in three different locations equidistant around the circumference. See Figure 1.
Figure 1, Aftertreatment SCR Catalyst Heat Shield Dimples
Resolution
Prior to performing any resolution which includes an ECM calibration and SCR catalyst part number update, troubleshoot any fault codes or symptoms included in the original complaint.
Follow the verification steps outlined above to determine an appropriate ECM calibration and aftertreatment SCR catalyst dependent on the level of repair being performed.
In addition, reference QuickServe Online under the Service tab for any applicable Temporary Repair Practices (TRP) or Campaigns for the subject engine.
If the ISX12/15 CM2350 Calibration Selection Tool directs replacement of the aftertreatment SCR catalyst, the compatible part numbers are located in Table 1.
