Aftertreatment #1 Intake NOx : Failure A failed aftertreatment intake NOx sensor has been detected.
3226-11
Aftertreatment #1 Outlet NOx : Other Failure Mode 3609-11
Aftertreatment #1 Outlet NOx : Other Failure Mode The aftertreatment outlet NOx sensor heater cannot generate enough heat or the power supply is intermittent.
3226-12
Aftertreatment #1 Outlet NOx : Failure 3609-12
Aftertreatment #1 Outlet NOx : Failure A failed aftertreatment outlet NOx sensor has been detected.
3360-12
Aftertreatment 1 Diesel Exhaust Fluid Controller : Failure 3820-12
Aftertreatment 1 Diesel Exhaust Fluid Controller : Failure A Diesel Exhaust Fluid Controller (DCU) has been flashed or a failed DCU has been detected.
3516–2
Aftertreatment #1 DEF Concentration: Erratic, Intermittent, or Incorrect 3100–2
Aftertreatment #1 DEF Concentration: Erratic, Intermittent, or Incorrect The DEF quality sensor is unable to read the DEF concentration due to an optical path obstruction.
3516–12
Aftertreatment #1 DEF Concentration: Failure 3100–12
Aftertreatment #1 DEF Concentration: Failure A failed DEF Quality Sensor has been detected Note: Turn the keyswitch to the OFF position before connecting or disconnecting these components.If the Caterpillar Electronic Technician (ET) will not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before you begin this procedure. The procedure verifies that electrical power is being supplied to the ECM and to the service tool connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. Cat ET also communicates with the ECM via the data links.The service tool connector contains connections for electrical power and for the data links.When the keyswitch is in the OFF position, Cat ET may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. In order to avoid this problem, place the keyswitch in the ON position when Cat ET is being used.Cat ET may display the following error message:"The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed."This message indicates that one of the following conditions exist:
The flash file in the ECM is newer than the version of Cat ET.
The latest version of Cat ET has not been installed.

Troubleshooting Test Steps Values Results
1. Check the Connectors
A. Turn the keyswitch to ON.
B. Connect to the "Engine #1 Aftertreatment Controller" using Cat ET.
C. Record all active and logged codes.
D. Turn the keyswitch to OFF.
E. Allow the system to completely power down before disconnecting connectors.
F. Thoroughly inspect the connectors that are associated with the data link circuits. Verify that the connectors are free of debris, free of corrosion and securely connected.
Connectors
Result: The connectors were connected properly and did not have corrosion or moisture.
If a -11 code is active or logged, Proceed to Test Step 2.
If a 3360-12 or 3820-12 code is active or logged, Proceed to Test Step 3.
If a 3216-12, 3655-12, 3226-12, or 3609-12 code is active or logged, replace the appropriate NOx sensor. Refer to Special Instruction, REHS8151 for special handling instructions. Proceed to Test Step 6.
Result: A 3516–12 or 3100–12 code is active or logged.
Repair: Replace the DEF tank header. Refer to the appropriate Disassembly and Assembly for removal and installation instructions. Proceed to Test Step 6.
Result: A 3516–2 or 3100–2 code is active or logged.
Proceed to Test Step 4.
Result: The connectors were not connected properly or the connectors did have corrosion or moisture.
Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. The DCU connector is not serviceable. Verify that the original problem is resolved.
2. Check the Voltage to the Suspect Sensor.
A. Disconnect the suspect sensor from the wiring harness.
B. Turn the keyswitch to ON.
C. Measure the voltage between battery "SUPPLY" and "RETURN" on the wiring harness connector of the suspect sensor.
Battery Voltage
Result: The measured voltage is equal to battery voltage.
Repair: Replace the failed NOx Sensor. Refer to Special Instruction, REHS8151 for special handling instructions.
Proceed to Test Step 6.
Result: The measured voltage is not equal to battery voltage.
Repair: There is a problem with an intermittent battery supply. Check the power supply to the suspect sensor.
Proceed to Test Step 6.
3. Perform the DEF Dosing Control Module Reset
A. Turn the keyswitch to ON.
B. Connect to the "Engine #1 Aftertreatment Controller" using Cat ET.
C. Perform the "DEF Dosing Control Module Reset".
Test Completed Successfully
Result: The test completed successfully and a 3360-12 or 3820-12 code is no longer active.
Return the unit to service.
Result: The test did not complete successfully and a 3360-12 or 3820-12 code is still active.
Repair: Replace the DCU.
Proceed to Test Step 6.
4. Check the Diesel Exhaust Fluid (DEF) Quality
A. Measure the DEF quality. Refer to Testing and Adjusting, Diesel Exhaust Fluid Quality - Test.
DEF
Result: The DEF is not contaminated and the concentration is not within the acceptable range.
Repair: Drain the DEF from the DEF tank. Refill the DEF tank with DEF that meets ISO 22241
