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 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.Communicating with the Wireless Communication Adapter (If so equipped)
Table 6 lists the optional hardware that is needed to connect Cat ET by using a wireless connection.Note: Some applications cannot use a wireless connection. Also, a dual data link cannot be used with a wireless connection.
