3516-2
(2017- Engines Onwards) 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.
The code is logged.
The warning lamp is illuminated.
3516-12
(2017- Engines Onwards) 3100-12 Aftertreatment #1 DEF Concentration: Failure The DEF quality 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 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.During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.
