639-9 247-9 J1939 Network #1 : Abnormal Update Rate
SAE J1939 Data Link : Abnormal Update Rate Communication has been lost to one or more of the devices on the datalink. If multiple devices are not communicating, there is likely a problem with the data link wiring, power, or ground circuits.
639-14 247-14 J1939 Network #1 : Special Instruction
SAE J1939 Data Link : Special Instruction The affected ECM is missing expected parameters. If the Cat® Electronic Technician (ET) will not communicate with the Electronic Control Module (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.

J1939 Network #2 Can B (Local) Refer to the application-specific wiring schematic for pin locations.-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.-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 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. Connect Cat ET.
2. Click the "Diagnostics" tab on the tool bar.
3. 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.
Proceed to "Check the Part Number of the Component" Table 5.
Result: A -14 code is active. Refer to the above -14 detected problems for additional information.
If the NOx sensors are listed as ECM 2, proceed to "Check the Part Number of the Component" Table 5.
For all other components, proceed to "Check for Incorrect Configuration Parameters" Table 6.
Table 5
Check the Part Number of the Component
Troubleshooting Test Steps Values Results
1. Locate the part number for the component that was identified by the "System Communication Status".
2. Check to see if the part number is correct for the application. Part Number Result: The part number is incorrect for the application.
Repair: Replace the component with the correct part number. Refer to Special Instruction, REHS8151 for special handling instructions if replacing a NOx sensor.
Proceed to "Use the Systems Communication Status to Determine the Communication Issue" Table 12.
Result: The part number is correct for the application.
Proceed to "Check for Incorrect Configuration Parameters" Table 6.

Check for Incorrect Configuration Parameters
Troubleshooting Test Steps Values Results
1. Connect Cat ET.
2. Use Cat ET to verify that the correct parameters are being used. Parameters Result: The parameters are correct.
Proceed to "Ensure that the latest Flash File Software is Installed in the ECM" Table 7.
Result: The parameters are not correct.
Repair: Input the correct parameters. Refer to Troubleshooting, "Configuration Parameters" for additional information.
If the problem is not resolved, proceed to "Ensure that the latest Flash File Software is Installed in the ECM" Table 7.
