- Connect cable (2) to the USB port of the PC.
Note: The communication adapter will power up when the adapter is connected to a PC or to an ECM that is powered up.
- Connect cable (4) to a service tool connector.
- Restore electrical power to the ECM. Verify that the "POWER" indicator on the communication adapter is illuminated. Make sure that the PC is powered up.
- Establish communication between Cat-ET and the ECM. If Cat-ET indicates that there is more than one ECM, select the engine ECM.
- If Cat-ET and the communication adapter do not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM".
Refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" if any of the following conditions exist:
- Cat-ET displays a message that refers to a communication problem.
- Cat-ET displays "Error #142 The interface hardware is not responding".
- Cat-ET displays a message that indicates that the firmware in the communications adapter is old.
- Cat-ET displays a message that refers to a communication problem.
Dual Data Link Communications (If so equipped)
When the connection of the communication adapter is complete, observe the communication adapter and Cat-ET. Certain applications require that dual data link communications be established in order to perform various test procedures. These tests will be listed in the "Diagnostic Tests" menu, some tests may not be available (grayed out). If there are diagnostic tests that are unavailable in Cat-ET, ensure that your service tool is communicating in dual data link mode.
Use the following indicators to confirm that Cat-ET is communicating on dual data links:
- "J1939" indicator is flashing
- "Cat Data Link" indicator is flashing
- Cat-ET is not displaying "Service tool support is limited"
Refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" if the "J1939" indicator and the "Cat Data Link" indicator are not flashing. Both indicators will be flashing during dual data link communications with the ECM.
