J1939 Code and Description CDL Code and Description Comments
3516-16
Aftertreatment #1 DEF Concentration : High - moderate severity (2) E1365 (2)
High Aftertreatment #1 DEF Concentration The Diesel Exhaust Fluid (DEF) has a high concentration.
The code is logged.
3516-18
Aftertreatment #1 DEF Concentration : Low - moderate severity (2) E1364 (1)
Low Aftertreatment #1 DEF Concentration The DEF has a low concentration.
The code is logged.
4364-2
Aftertreatment #1 SCR Catalyst Conversion Efficiency : Erratic, Intermittent, or Incorrect E1410 (1)
Invalid Aftertreatment #1 SCR Conversion Efficiency An abnormally low value of NOx conversion has been detected based on the engine out and tailpipe NOx level sensor readings.
4364-17
Aftertreatment #1 SCR Catalyst Conversion Efficiency : Low - least severe (1) E1309 (1)
Low Aftertreatment #1 SCR Catalyst Conversion Efficiency The SCR System is not able to reduce NOx in the exhaust system.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: An E1410 (1) or 4364-2 code is active or logged.
Proceed to Test Step 2.
Result: For all active or logged codes other than an E1410 (1) or 4364-2.
Proceed to Test Step 3.

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 Special Instruction, REHS8151 for the correct handling procedures.
D. Start the engine.
E. Connect Cat ET.
F. Select the "Selective Catalyst Reduction System".
G. Use Cat ET to perform the following diagnostic test:
-"Aftertreatment System Functional Test"
NOx Sensors
Result: The test was successful.
Return to service.
Result: The test was not successful.
Repair: Proceed to Test Step 3.
3. Inspect the Exhaust System
A. Start the engine.
B. Check the exhaust system for leaks or damage.
C. Check all the exhaust connections from the turbocharger outlet to the tailpipe outlet.
D. Check the exhaust system insulation for damage.
Exhaust System
Result: The exhaust system is OK.
Proceed to Test Step 4.
Result: The exhaust system is NOT OK.
Repair: Repair or replace the damaged exhaust component.
Proceed to Test Step 9.
4. Check the Diesel Exhaust Fluid (DEF) Quality
A. Measure the DEF quality. Refer to Testing and Adjusting, Diesel Exhaust Fluid Quality - Test for additional information.
DEF Quality
Result: The DEF not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 5.
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 9.
Result: The DEF is contaminated.
Repair: Contact the DSN for addition information.

5. Inspect the DEF Lines for Leaks
A. Turn the keyswitch to the ON position. Do not start the engine.
B. Connect Cat ET.
C. Select the appropriate "Diesel Exhaust Fluid Control Unit (DCU)".
D. Use Cat ET to perform the following diagnostic test to pressurize the system:
- For DEF System #1, perform the "Aftertreatment #1 DEF Dosing System #1 Prime Test".
- For DEF System #2, perform the "Aftertreatment #1 DEF Dosing System #2 Prime Test".
E. Visually inspect all DEF lines from the tank to the DEF injectors. Look for pinched, damaged, or disconnected lines.
F. Turn the keyswitch to the OFF position.
DEF Lines
Result: The lines are not leaking, damaged, pinched, or disconnected.
Proceed to Test Step 6.
Repair: The lines are leaking, damaged, pinched, or disconnected.
Result: Repair or replace the damaged components.
Proceed to Test Step 9.
