Note: The Cat ET is a software program that is used with an IBM compatible personal computer.
In order to use the Cat ET, order the following materials: Special Publication, JERD2124, "ET Single Use Program License", Special Publication, JEHP1026, "Information and Requirements Sheet", 7X-1425 Data Link Cable and the Data Subscription and Special Publication, JERD2142, "Data Subscription". The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of the ET.
The Cat ET is not required in order to determine the diagnostic codes and the Cat ET is not required in order to clear the diagnostic codes. However, the process of determining the diagnostic codes is easier and faster by using the Cat ET. The Cat ET can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow the Cat ET to be a useful tool for troubleshooting.
The Cat ET connects to the machine diagnostic connector and the Cat ET communicates with the electronic control modules over the data link. The diagnostic connector is located by the fuse panel. For more information and the locations of the connectors, see Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine's Service Manual.
Connect the Cat ET to the machine. Turn the key start switch to the RUN position. Start the Cat ET. The Cat ET will initiate communications with the electronic control modules on the machine. The Cat ET will list the available electronic control modules on the machine after communication has been established.
