Troubleshooting Test Steps Values Results
1. 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. 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 code is active or logged.
Proceed to Test Step 2.
Result: A 3516–11, 3516-15 , 3516-18, or 4364-18 code is active or logged.
Proceed to Test Step 3.
Result: A 7105-31 diagnostic code is active or logged.
Proceed to Test Step 17.
2. 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 Disassembly and Assembly, Nitrogen Oxide Sensor - Remove and Install 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.
3. 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 12.
Result : The DEF is not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 4.
Result : The DEF is contaminated.
Contact the Dealer Solutions Network (DSN) for further information.
4. Determine the Diagnostic Code
A. Use the electronic service tool to check active or logged diagnostic codes.
Diagnostic codes
Result : A or 3516–11, 3516-15 or 3516-18 code is active or logged.
Repair: Replace the DEF tank header assembly. Refer to Disassembly and Assembly, Manifold (DEF Heater) - Remove and Install for the correct procedure.
Proceed to Test Step 12.
Result : A 4364-18 code is active or logged.
Proceed to Test Step 5.
5. Check the Turbocharger Actuator Rod
A. Check that the turbocharger wastegate actuator rod is securely attached to the wastegate.
B. Use the electronic service tool to perform the "Air System Motor Valves Verification Test". Check for active diagnostic codes that relate to the turbocharger electronic wastegate.
Turbocharger wastegate actuator rod
Result : The turbocharger wastegate actuator rod is detached from the wastegate. The retaining clip is missing.
Contact the Dealer Solutions Network (DSN) for further information.
Result: There are active diagnostic codes that relate to the turbocharger electronic wastegate.
Repair: Troubleshoot the active diagnostic codes. Refer to Troubleshooting, Diagnostic Trouble Codes.
Proceed to Test Step 12.
Result : The turbocharger wastegate actuator rod is securely attached to the wastegate. The retaining clip is securely installed. The turbocharger electronic wastegate is operating to specification.
Proceed to Test Step 6.
6. Inspect All the DEF Lines for Leaks
A. Turn the keyswitch to the ON position. Do not start the engine.
B. Use the electronic service tool to perform the "DEF Dosing System Verification Test" to pressurize the system. Refer to Troubleshooting, "Service Tool Features" for more information.
C. Visually inspect all DEF lines from the DEF tank to the DEF injector. Look for pinched, damaged, or disconnected lines.
D. Inspect the lines for leakage.
E. Turn the keyswitch to the OFF position.
Leaks
Result: The lines are leaking, damaged, pinched, or disconnected.
Repair: Make the necessary repairs.
Proceed to Test Step 12.
Result: The lines are not leaking, damaged, pinched, or disconnected.
Proceed to Test Step 7.
7. Perform a DEF Dosing System Accuracy Test
A. Perform the "DEF Dosing System Accuracy Test". Refer to Systems Operation, Testing and Adjusting, "Aftertreatment SCR System Dosing Test" for the correct procedure.
DEF dosing system accuracy test
Result: The amount of DEF collected is within specification.
Install the DEF injector. Refer to Disas
