5965-5 3838-5
5965-6 3838-6
5966-6 3965-6 If the Cat® 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 Systems Communication Status is located under the diagnostics tab in Cat ET. Click the "System Communication Status" option. Once the screen opens up, the information will automatically be loaded from the ECM. If there is an issue with the data link and the data link is repaired, the "Load from ECM" button will have to be clicked again to see the updated status. If there are communication issues between multiple modules, each module can be selected individually to determine which components are having communication issues. If the problem is intermittent, the "View History" button can be clicked to see all the communication faults that have previously logged.

Illustration 1 g06156053Note: The DEF Quality Sensor is only available on 2017model or later.-9 Detected Problems:Device 1 is unable to communicate on the data link.
Device 1 cannot communicate with other devices on the data link, but can communicate with the service tool, indicating a problem with the data link wiring.Device 1 is unable to communicate with Device 2 on the data link.
Device 1 cannot communicate with Device 2, indicating a problem with the data link wiring, power or ground circuit, or Device 2.Note: If a 639-9 or 247-9 code is active and the "System Communication Status" indicates a communication problem with the "Aftertreatment #1 DEF Sensor", confirm that the "Aftertreatment #1 DEF Quality Sensor Installation Status" configuration parameter is programmed properly.The "Aftertreatment #1 DEF Quality Sensor Installation Status" parameter must be programmed to "Not Installed", if equipped with a DEF header having a 3-pin connector without an internal DEF quality sensor.-14 Detected Problems:Device 1 is unable to obtain a network address on the data link.
Device 1 is trying to claim the same address as another Device. An example of this is 2 devices being configured the same.Device 1 detects a failed address claim from Device 2 on the data link.
Device 1 detects that Device 2 is trying to claim the same address as another device.Device 1 is not receiving all expected parameters from Device 2 on the data link.
A component is configured as installed in the device, but is not installed on the application.
The incorrect component is installed.
The incorrect software file has been installed.

Troubleshooting Test Steps Values Results
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between Cat ET and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Troubleshoot any associated diagnostic codes that are present before continuing with this procedure.
Associated Codes
Result: An associated diagnostic trouble code is not active or logged.
Proceed to Test Step 2.
Result: An associated code is active or logged.
Repair: Troubleshoot the associated codes before continuing with this procedure.
Refer to Troubleshooting, "Diagnostic Trouble Codes" to troubleshoot the associated diagnostic code.
2. Use the "System Communication Status" to Determine the Communication Issue
A. In Cat ET, click the "Diagnostics" tab on the tool bar.
B. Select the "System Communication Status" option from the drop-down list.
Note: The Aftertreatment #1 Intake NOx Level Sensor is displayed as Aftertreatment #1 Information #1 in some versions of software.
Component Identified
Result: A -9 code is active.
Repair: Refer to the above -9 detected problems for more information.
