Troubleshooting Test Steps Values Results
1. Determine the Code.
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM).
B. Download the "Warranty Report" from the Aftertreatment ECM before performing any troubleshooting or clearing any diagnostic trouble codes.
C. Determine the diagnostic trouble code that is active.
Diagnostic Code
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 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 4.
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 4.
4. 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
