639-9
J1939 Network #1 : Abnormal Update Rate 247-9
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
J1939 Network #1 : Special Instruction 247-14
SAE J1939 Data Link : Special Instruction The affected Electronic Control Module (ECM) is missing expected parameters.
1231-9
J1939 Network #2 : Abnormal Update Rate 2348-9
SAE J1939 Data Link #2 : 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.
1231-14
J1939 Network #2 : Special Instruction 2348-14
SAE J1939 Data Link #2 : Special Instruction The affected ECM is missing expected parameters.
2853-9
Communications Connection : Abnormal Update Rate N/A 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. 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.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the diagnostic code.
Codes
Result: An associated code is active.
Repair: Troubleshoot the associated code before continuing with this test.
Result: An associated code is not active or logged.
Proceed to Test Step 2.
2. Check for Codes
A. Connect Cat ET.
B. Determine if a code is active or logged.
Codes
Result: A -9 code is active.
Proceed to Test Step 6.
Result: A -14 code is active.
Proceed to Test Step 3.
3. Check the Part Number of the Component
A. Locate the part number of the component that was identified by the "System Communication Status".
B. Check to see if the part number is correct for the application.
Part number
Result: The part number is correct for the application.
Proceed to Test Step 4.
Result: The part number is incorrect for the application.
Proceed to Test Step 10.
4. Check the Programmable Parameters
A. Connect Cat ET.
B. Identify the component that logged the -14 code.
C. Use Cat ET to verify that the correct parameters are being used.
Parameters
Result: The parameters are correct.
Proceed to Test Step 5.
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 Test Step 5.
5. Ensure that the latest Flash File Software is Installed in the ECM
A. Connect Cat ET.
B. Use Cat ET to verify that the correct flash file is being used.
Flash file
Result: The flash file is correct for the application.
Repair: A failed component has been identified. Replace the failed component.
Proceed to Test Step 10.
Result: The flash file is incorrect for the application.
Repair: Reflash the component to the correct flash file.
Proceed to Test Step 10.
