Troubleshooting Test Steps Values Results
1. Check that the latest available software is installed and there are no applicable Technical Information Bulletins or Special Instruction documentation released
A. Ensure that the latest software is installed on the engine ECM.
If necessary, refer to Troubleshooting, "ECM Software - Install" for the correct procedure.
B. Ensure all Technical Information Bulletins and/or Special Instruction documented for the issue and/or product are reviewed and followed.
Software and Publications
Result: The latest software is not installed.
Repair: Install the latest engine ECM software. If necessary, refer to Troubleshooting, "ECM Software - Install" for the correct procedure.
Start the engine and wait for 2 minutes.
If the fault is cleared, return the engine to service.
If the fault is still present, proceed to Test Step 2.
Result: Applicable Technical Information Bulletin/Special Instruction publication is available.
Repair: Review and follow instructions provided in the available publication.
Result: The latest software is installed.
Proceed to Test Step 2.
2. Determine the Code
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the ECM before troubleshooting or clearing diagnostic trouble codes.
C. Determine the diagnostic trouble code that is active.
Diagnostic trouble code
Result: An associated code is active or logged.
Note: Troubleshoot associated codes before continuing with this procedure.
Refer to Troubleshooting, "Diagnostic Trouble Codes" for further information.
Result: A 4364-2 (E1410 (2)) code is active or logged.
Proceed to Test Step 3.
Result: A 3516-16 (E1365 (2)), 3516-18 (E1364 (2)) or 4364-18 (E1309 (2)) code is active or logged.
Proceed to Test Step 4.
Result: A 7105-31 (E1585 (2)) code is active or logged.
If the fault cleared as a result of updating to the latest software, return the unit to service.
If the fault is still present, proceed to Test Step 22.
3. Check the NOx sensors for proper installation.
A. Turn the keyswitch to the OFF position.
B. Verify that the sensors are located in the correct position.
Note : The "Engine Out NOx" sensor wiring has a black sheath. The "Tailpipe Out NOx" sensor wiring has a gray sheath.
C. If the sensors are installed in the wrong positions, install the sensors in the correct positions. Refer to Special Instruction, "REHS8151" for the correct handling procedures.
D. Use the electronic service tool to perform the "Aftertreatment System Functional Test".
NOx sensors
Result : The "Aftertreatment System Functional Test" completed successfully.
Return the unit to service.
Result : The "Aftertreatment System Functional Test" did not complete successfully and other codes were logged.
Repair: Troubleshoot the logged codes. Refer to Troubleshooting, "Diagnostic Trouble Codes" for the code that became active during the test.
4. Check the DEF Level and Temperature
DEF Level and Quality
Result: The DEF level is above 30% and the DEF tank temperature is below 58° C (136° F).
Proceed to Test Step 5.
Result: The DEF tank level is below 30% or the DEF tank temperature is above 58° C (136° F).
Repair : Refill the DEF tank to above 50% level and ensure that the DEF tank temperature is below 58° C (136° F).
Proceed to Test Step 5.
5. Check the Diesel Exhaust Fluid (DEF) Quality
A. Measure the DEF quality. Refer to Systems Operation, Testing and Adjusting, Diesel Exhaust Fluid Quality - Test for the correct procedure.
DEF
Result : The DEF is not contaminated and the concentration is not within the acceptable range.
Repair: Drain the DEF from the tank. Refill the tank with DEF that meets ISO 22241 quality standards.
Proceed to Test Step 16.
Result : The DEF is not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 6.
Result : The DEF is contaminated.
Repair: Flush the DEF tank. Refer to Systems Operation, Testing and Adjusting, Diesel Exhaust Fluid Tank - Flush for the correct procedure.
Proceed to Test Step 16.
6. Determine the DEF Quality Sensor Installation Status
A. Use the electronic service tool to check the status of Configuration Parameter "Aftertreatment #1 DEF Quality Sensor Installation Status".
