Test Step 1. Determine the ProblemIdentify the communication problem.Note: If Cat ET is not communicating and the "POWER" indicator is not illuminated, cycle the power to the communications adapter.Expected Result:Both indicators on the communication adapter are not flashing.Results:
Both indicators on the communication adapter are not flashing. - Proceed to Test Step 2.
Cat ET indicates the engine must be serviced on two both links. - Proceed to Test Step 2.
Cat ET displays a message that indicates the firmware in the communication adapter does not support communication on both data links. - Proceed to Test Step 3.
Cat ET displays a "Error #142 The interface hardware is not responding" message. - Proceed to Test Step 3.
Cat ET displays a message that indicates that Cat ET cannot find an exact match for the software version in the ECM. - Repair: Update Cat ET to the latest available version.STOP
The power indicator is not illuminated. - Proceed to Test Step 5.Test Step 2. Verify that the Correct Communication Adapter is being UsedA 317-7484 Communication Adapter Gp must be used to communicate. The following communication adapters cannot be used because the communication adapters do not communicate over both data links:
Wireless communication adapter
7X-1701 Communication Adapter AsIdentify the communication adapter that is being used.Expected Result:An incorrect communication adapter is being used.Results:
An incorrect communication adapter is being used. - Repair: Obtain the correct communication adapter. Refer to Troubleshooting, "Electronic Service Tools", if necessary.Establish communication on both data links. Continue with this procedure if the communication adapter does not communicate on both data links.
A correct communication adapter is being used. However, the "Power" indicator is not illuminated. - Proceed to Test Step 5.
A correct communication adapter is being used. The "Power" indicator is illuminated. - Proceed to Test Step 4.Test Step 3. Check the Version of the Firmware for the Communication AdapterNote: The version of the firmware for the communication adapter must be "3.0.0" or higher.
Electronically disconnect Cat ET. Verify that the "power" indicator on the communication adapter is illuminated.
Select the "Utilities" drop-down menu.
Select "Comm Adapter II Toolkit" from the menu.
When the dialog box for the tool kit appears, select the "Utilities" drop-down menu.
Select "Application Firmware Flash" from the menu.
Select the latest ".apf" file from the list.
Click "OK". Then, click "Begin Flash".
When the file is loaded, the "Flash Completed Successfully" message will appear.
Click "Toolkit". Verify that the "Application Firmware Version (Serial IP)" is "3.0.0" or higher.
Attempt to connect Cat ET. Expected Result:Cat ET communicates on both data links.Results:
OK - Cat ET communicates on both data links.STOP
Not OK - Cat ET does not communicate using both data links. Proceed to Test Step 4.Test Step 4. Verify that Cat ET is Configured CorrectlyCat ET must be configured correctly in order to communicate on both data links. Perform the following procedure:
Select the "Utilities" drop-down menu.
Click on the "Preferences" menu.
Select the "Commmunications" tab.
Verify that "Caterpillar Communication Adapter II (Serial IP)" is selected. If "Caterpillar Communication Adapter II (Serial IP)" is not an option for selection, the version of Cat ET is incorrect. Ensure that version "2007B" has been installed.If necessary, update the version of Cat ET. Then, perform this Test Step again.
Verify that the port is correct.
Verify that the "Enable Dual Data Link Service" option is checked.
Click "OK". Note: Cat ET must reconnect in order for any changes to be recognized.
Electronically disconnect Cat ET if changes were made to any of the settings for communications. Electronically connect Cat ET. Attempt to establish communication. Observe the indicators on the communication adapter. A "limited support" warning should not be displayed. The "J1939 / DeviceNet" and "Cat Data Link" indicators should be flashing. If these indicators are flashing, Cat ET is communicating on both data links.Expected Result:Cat ET is communicating on both data links.Results:
OK - Cat ET communicates on both data links.STOP
Not OK - Cat ET does not communicate on both data links. The "POWER" indicator is not illuminated. Proceed to Test Step 5.
No - Cat ET does not communicate on both data links. The "POWER" indicator is illuminated. Proceed to Test Step 6.Test Step 5. Check the Electrical Power to the Communication Adapter

Power terminals at the service tool connector
(Terminal A) +Battery
(Terminal B) −Battery Check for battery voltage at the service tool connector. Refer to Illustration 1.Expected Result:Battery voltage is present at the service tool connector.Results:
OK - Battery voltage is present at the service tool connector.Repair: Verify that the cable between the service tool connector and the communication adapter is OK. Replace the cable, if necessary.Replace the communication adapter if the following conditions are true:
There is power at the harness connector for the communication adapter.
The communication adapter's "POWER" indicator is not illuminated.STOP
Battery voltage is not present at the service tool connector. - Repair: Inspect the application wiring and fuses. Determine the cause of the missing voltage. Make the necessary repairs.Attempt to establish communication after the electrical power is at the service tool connector. Proceed to Test Step 6 if the service tool will not communicate on both data links.Test Step 6. Check the Electrical Power to the ECM
Verify that electrical power for the application is turned on.
