Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM).
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing any diagnostic trouble codes.
C. Determine the diagnostic trouble code that is active.
Codes
Result : A E1410 (2) or 4364-2 code is active or logged.
Proceed to Test Step 2.
Result : For all codes other than a E1410 (2) or 4364-2.
Proceed to Test Step 3.
2. Check the NOx Sensors for Proper Installation.
A. Turn the keyswitch to OFF.
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. Perform a "Aftertreatment System Functional Test" using Cat ET.
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.
3. Check the Diesel Exhaust Fluid (DEF) Quality.
A. Measure the DEF quality. Refer to Testing and Adjusting, "Diesel Exhaust Fluid Quality - Test" for the correct procedure.
DEF
Result: The DEF is not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 4.
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 14.
Result : The DEF is contaminated.
Repair : Contact the DSN for further information.
4. Determine the DEF Quality Sensor Installation Status
A. Use Cat ET to check the status of the configuration parameter "Aftertreatment #1 DEF Quality Sensor Installation Status".
Parameter
Result : "Aftertreatment #1 DEF Quality Sensor Installation Status" is set to "Installed".
Proceed to Test Step 5.
Result : "Aftertreatment #1 DEF Quality Sensor Installation Status" is set to "Not Installed" or is not listed.
Proceed to Test Step 6.
5. Check for Codes
A. Connect Cat ET
B. Determine the code that is active.
Codes
Result : An E1309 (2) or 4364–18 code is active or logged.
Proceed to Test Step 6.
Result : An
