Test Step 1. Determine the ProblemDetermine the communication problem.Note: Disconnect electrical power to the communication adapter and connect electrical power to the communication adapter if an indicator other than the "POWER" indicator is illuminated when Cat ET is not communicating with an ECM.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 is intended to 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 171-4401 Communication Adapter As or a 275-5121 Communication Adapter As 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 AsDetermine 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: Connect a correct communication adapter. Refer to Troubleshooting, "Electronic Service Tools", if necessary.Attempt to establish communication. 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.
Click on the "Utilities" menu.
Click on the "Comm Adapter II Toolkit" menu.
Wait for the tool kit to open. Then, click on the "Utilities" menu.
Click "Application Firmware Flash".
Select the latest ".apf" file from the list.
Click "OK". Then, click "Begin Flash".
Wait for the "Flashs Completed Successfully" message to 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:
Yes - Cat ET communicates on both data links.STOP
No - Cat ET does not communicate on 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:
Click on the "Utilities" 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. Version "2007B" or higher must be used.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 used.
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. At this point, a "limited support" warning should not be displayed. The "J1939 / DeviceNet" and "J1708" indicators should be flashing. This indicates that Cat ET is communicating on both data links.Expected Result:Cat ET is communicating on both data links.Results:
Yes - Cat ET communicates on both data links.STOP
No - 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
Illustration 1 g01335846
Power terminals on the service tool connectors.
Refer to Illustration 1. Check for battery voltage at the service tool connector. Expected Result:Battery voltage is not present at the service tool connector.Results:
Battery voltage is not present at the service tool connector. - Repair: Inspect the vehicle's 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 does not communicate on both data links.
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 cable's "DATA LINK" connector.
The communication adapter's "POWER" indicator is not illuminated.STOPTest Step 6. Check the Electrical Power to the ECM
Verify that the keyswitch is ON.
Illustration 2 g01335850
General information about the electrical power to the ECM
Refer to Illustration 2. Verify that battery voltage is present at the terminals that are indicated in the Illustration. Be sure to connect the voltmeter between the "UNSWITCHED +BATTERY" terminals and the "-BATTERY" terminals.
Verify that battery voltage is present at P1-70. Expected Result:Battery voltage is missing from a P1 terminal.Results:
Yes - Battery voltage is missing from a P1 terminal.Repair: Inspect the vehicle's wiring and fuses. Determine the cause of the missing voltage. Make the necessary repairs.Attempt to establish communication after the electrical power is at all of the appropriate P1 terminals. Continue with this procedure, if necessary.STOP
No - Battery voltage is present at all of the appropriate P1 terminals. Proceed to the Test Step 7.Test Step 7. Try to Establish Communication With a Bypass Harness
Connect the communication adapter to the engine ECM with a 167-9225 Harness (SERVICE TOOL ADAPTER). This harness supports communication on both data links.
