(code descriptions may vary) Comments
3216-11 3002-11 Aftertreatment #1 Intake NOx : Other Failure Mode The NOx sensor cannot reach the correct operating temperature in the defined time period
3216-12 3002-12 Aftertreatment #1 Intake NOx : Failure The data received from the NOx sensor is out of range.
The code is logged.
The warning lamp is illuminated.
3226-11 3609-11 Aftertreatment #1 Outlet NOx : Other Failure Mode The NOx sensor cannot reach the correct operating temperature in the defined time period
3226-12 3609-12 Aftertreatment #1 Outlet NOx : Failure The data received from the NOx sensor is out of range.
The code is logged.
The warning lamp is illuminated.
4377-12 3138-12 Aftertreatment #1 Outlet NH3 : Failure
(DOC/SCR engines only) The data received from the ammonia (NH3) sensor is out of range.
The code is logged.
The warning lamp is illuminated. If the electronic service tool will not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before starting this procedure. The procedure verifies that electrical power is being supplied to the ECM and to the diagnostic connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. The electronic service tool also communicates with the ECM via the data links.The diagnostic connector contains connections for electrical power and for the data links.When the keyswitch is in the OFF position, the electronic service tool may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. To avoid any disruption, place the keyswitch in the ON position when the electronic service tool is being used.The electronic service tool 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 exists:
The flash file in the ECM is newer than the version of the electronic service tool.
The latest version of the electronic service tool has not been installed.

Troubleshooting Test Steps Values Results
1. Check the Connectors
A. 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.
B. Perform a 45 N (10 lb) pull test on all the wires associated with the data link circuits.
Connectors
Result: The connectors were connected correctly and did not have corrosion or moisture.
Proceed to Test Step 2.
Result: The connectors were not connected correctly or the connectors have corrosion or moisture.
Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. The DCU connector is not serviceable.
Proceed to Test Step 8.
2. Check for Active or Recently Logged Diagnostic Codes
A.Establish communication between the electronic service tool and the engine Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools"
B.Download the "Warranty Report" from the engine ECM before troubleshooting or clearing diagnostic trouble codes.
C.Establish communication between the electronic service tool and the Dosing Control Unit (DCU) .
D. Look for active or logged codes.
Diagnostic Trouble Codes
Result: There is an active or recently logged 3216-11(3002–11) or 3226-11(3609–11) diagnostic code.
Proceed to Test Step 3.
Result: There is an active or recently logged 3216-12(3002–12) diagnostic code.
Proceed to Test Step 4.
Result: There is an active or recently logged 3226-12(3609–12) diagnostic code.
Proceed to Test Step 5.
Result: There is an active or recently logged 4377-12(3138–12) diagnostic code.
Proceed to Test Step 6.
3. Inspect the NOx Sensor
A. Remove the suspect NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
B. Inspect the NOx sensor for visible damage.
NOx sensor OK
Result: The NOx sensor is damaged.
Repair: Ensure that the latest engine software is installed. Refer to Troubleshooting, ECM Software - Install for the correct procedure.
Install a replacement NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 8.
Result: The NOx sensor is not damaged.
Repair: Clean the NOx sensor using only a soft brush.
Note: Do not use abrasive materials or fluids to clean the NOx sensor.
Reinstall the NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 8.
4. Override the SCR Intake NOx Sensor
A.Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position.
C. Use the electronic service tool to perform the "Aftertreatment #1 Intake NOx Level Sensor Power Supply Override" .
D. Check for active diagnostic codes.
Diagnostic trouble codes
Result: The 3216-12(3002–12) diagnostic code is no longer active.
Proceed to Test Step 8.
Result: The 3216-12(3002–12) diagnostic code is still active.
Repair: Ensure that the latest engine software is installed. Refer to Troubleshooting, ECM Software - Install for the correct procedure.
Install a replacement NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 8.
5. Override the SCR Outlet NOx Sensor
A. Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position.
C. Use the electronic service tool to perform the "Aftertreatment #1 Outlet #1 NOx Level Sensor Power Supply Override" .
D. Check for active diagnostic codes.
Diagnostic trouble codes
Result: The 3226-12(3609–12) diagnostic code is no longer active.
Proceed to Test Step 8.
Result: The 3226-12(3609–12) diagnostic code is still active.
Repair: Inspect the SCR outlet NOX sensor probe. If there are soot deposits on the probe, the DPF may have failed.
Ensure that the latest engine software is installed. Refer to Troubleshooting, ECM Software - Install for the correct procedure.
If the SCR outlet sensor probe does not have soot deposits, install a replacement NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 8.
6. Override the Ammonia Sensor
A. Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position.
C. Use the electronic service tool to reset the active 4377–12 diagnostic code.
D. Use the electronic service tool to perform the "Aftertreatment #1 DEF Dosing Control Module Key Switch Line Override".
E. Check for active diagnostic codes.
