Diagnostic Trouble Codes for the Data Link Sensors
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
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.
3226-12 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.
5742-12 5405-12 Aftertreatment DPF Temperature Sensor Module : Failure The DPF inlet temperature sensor has failed.
The code is logged.
The warning lamp is illuminated.
5743-12 3105-12 Aftertreatment SCR Temperature Sensor Module : Failure The SCR inlet temperature sensor has failed.
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 CAN data link is used to communicate information between the engine ECM and sensors that are a part of the application. The electronic service tool also communicates with the ECM via the CAN data link.The diagnostic connector contains connections for electrical power and for the CAN data link.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.During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Check the Connectors
A. Turn the keyswitch to the ON position.
B. Connect the electronic service tool to the diagnostic connector.
C. Record all active and logged codes.
D. Turn the keyswitch to the OFF position.
E. Allow the system to completely power down before disconnecting connectors.
F. Thoroughly inspect the connectors that are associated with the data link sensor 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 diagnostic code 3216-12 (3002-12) or 3226-12 (3609-12) code is active or logged, replace the applicable NOx sensor. Proceed to Test Step 2.
If diagnostic code 5743-12 (3105-12) is active or logged, confirm that the CAN C data link is operating correctly. Refer to Troubleshooting, CAN Data Link - Test. If the CAN C data link is OK, replace the aftertreatment combined temperature sensor. Refer to Disassembly and Assembly, Temperature Sensor - Remove and Install (Combined SCR and DPF Temperature Sensor) or Disassembly and Assembly, Temperature Sensor - Remove and Install (Combined SCR, DOC, and DPF Temperature Sensor).
Proceed to Test Step 2.
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.
Proceed to Test Step 2.
2. Perform the Aftertreatment System Functional Test.
A. Turn the keyswitch to the ON position.
B. Start the engine.
C. Connect the electronic service tool to the diagnostic connector.
D. Perform the "Aftertreatment System Functional Test".
Test completed successfully
Result: The test passed and no diagnostic codes became active.
Return the unit to service.
Result: A fault came active.
Repair: Troubleshoot the fault that became active during the "Aftertreatment System Functional Test".
If the fault is still present, contact the Dealer Solutions Network (DSN).
