Diagnostic Trouble Codes for the Data Link Sensors
J1939 Code Code Description Comments
3216-12 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.
3226-12 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.
5742–12 Aftertreatment Diesel Particulate Filter Temperature Sensor Module : Failure The data received from the Diesel Oxidation Catalyst (DOC)/Diesel Particulate Filter (DPF) inlet temperature sensor is out of range.
The code is logged.
The warning lamp is illuminated.
5743–12 Aftertreatment 1 SCR Temperature Sensor Module : Failure The data received from the Selective Catalytic Reduction (SCR) inlet temperature 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 exist:
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.

Schematic for the data-type sensors
Not all connectors are shown. Refer to the appropriate Electrical Schematic.
Note: All connectors may not be shown. Refer to the Electrical Schematic for the application for details of any connectors between the sensor connectors and the ECM connectors.Note: Some engines are equipped with a triple-probe sensor for the DOC, the DPF, and the SCR inlet temperatures.Some engines are equipped with a dual-probe sensor for the DOC and DPF inlet temperatures and a single-probe sensor for the SCR inlet temperature.Complete the procedure in the order in which the steps are listed.

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.
Proceed to Test Step 5.
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. Look for active or logged codes.
Diagnostic Trouble Codes
Result: There is an active or recently logged 3216-12 diagnostic code.
Proceed to Test Step 3.
Result: There is an active or recently logged 3226-12 diagnostic code.
Proceed to Test Step 4.
Result: There is an active or recently logged 5742–12 diagnostic code.
Repair: Install a replacement DPF/DOC inlet temperature sensor. Refer to Disassembly and Assembly, Temperature Sensor (Exhaust) - Remove and Install (Temperature Sensor for Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and (Selective Catalyst Reduction (SCR)).
Proceed to Test Step 5.
Result: There is an active or recently logged 5743–12 diagnostic code.
Repair: Install a replacement SCR inlet temperature sensor.
Proceed to Test Step 5.
3. 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 diagnostic code is no longer active.
Proceed to Test Step 5.
Result: The 3216-12 diagnostic code is still active.
Repair: Install a replacement NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 5.
4. 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 diagnostic code is no longer active.
Proceed to Test Step 5.
Result: The 3226-12 diagnostic code is still active.
Repair: Install a replacement NOx sensor. Refer to Disassembly and Assembly for the correct procedure.
Proceed to Test Step 5.
5. Perform the "Aftertreatment System Functional Test"
A. Turn the keyswitch to the ON position.
B. Use the electronic service tool to perform the "Aftertreatment System Functional Test".
Diagnostic Codes
Result: The test passed and no diagnostic codes became active.
Return the engine to service.
Result: The test failed.
Troubleshoot any diagnostic codes that became active during the test. Refer to Troubleshooting"Diagnostic Trouble Codes".
If the procedure did not correct the fault, contact the Dealer Solutions Network (DSN).
