639-9
J1939 Network #1 : Abnormal Update Rate 247-9
SAE J1939 Data Link : Abnormal Update Rate Communication has been lost to one of the devices on the datalink.
If multiple devices are not communicating, there is likely a problem with the datalink.
1231-9
J1939 Network #2 : Abnormal Update Rate 2348-9
SAE J1939 Data Link #2 : Abnormal Update Rate Communication has been lost to one of the devices on the datalink.
If multiple devices are not communicating, there is likely a problem with the datalink.
1231-14
J1939 Network #2 : Special Instruction 2348-14
SAE J1939 Data Link #2 : Special Instruction The affected Electronic Control Module (ECM) is missing expected parameters.
6806-14
ECU Interface Mismatch : Special Instruction E1787 (2)
ECM #1 Interface Mismatch The ECM detects incorrect software is installed on the Gas Actuation Valve (GAV) ECM
7499-14
ECU #2 Interface Mismatch : Special Instruction E1788 (2)
ECM #2 Interface Mismatch The ECM detects incorrect software is installed on the In Cylinder Pressure Sensor (ICPS) ECM
N/A 296-9
Transmission Control : Abnormal Update Rate Communication has been lost to one of the devices on the datalink.
If multiple devices are not communicating, there is likely a problem with the datalink.
N/A 296-14
Transmission Control : Special Instruction The affected ECM is missing expected parameters.
N/A 800-9
VIMS Main Module : Abnormal Update Rate Communication has been lost to one of the devices on the datalink.
If multiple devices are not communicating, there is likely a problem with the datalink.
N/A 800-14
VIMS Main Module : 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.

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 any associated codes before continuing with this test.
Result: An associated diagnostic trouble code is not active or logged.
Proceed to Test Step 2.
2. Use the "System Communication Status" to Determine the Communication Issue
A. Connect Cat ET.
B. Click the "Diagnostics" tab on the tool bar.
C. Select the "System Communication Status" option from the drop-down list.
Component Identified
Result: A -9 code is active. Refer to the above -9 detected problems for additional information.
Proceed to Test Step 6.
Result: A -14 code is active. Refer to the above -14 detected problems for additional information.
Proceed to Test Step 3.
3. Check for Incorrect Configuration Parameters
A. Connect Cat ET.
B. Use Cat ET to verify that the correct parameters are being used.
Parameters
Result: The parameters are correct.
Proceed to Test Step 4.
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 4.
4. Ensure that the latest Flash File Software is Installed in all the ECMs
A. Connect Cat ET.
B. Use Cat ET to verify that the correct flash file is being used.
Flash File
Result: The latest flash file is installed.
Proceed to Test Step 9.
Result: The latest flash file is not installed.
Repair: Perform the following procedure:
1. Download the latest flash file from SIS web.
2. Install the software into the ECM.
Refer to Troubleshooting, "ECM Software - Install" for additional information.
Proceed to Test Step 9.
