Reference: 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", Special Publication, JERD2142, "Data Subscription" and 7X-1425 Data Link Cable. The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of CAT ET.
The service tool (ET) is not needed in order to determine diagnostic codes. However, the process of determining diagnostic codes is easier with the CAT ET. The ET can also display information on the diagnostic code history and the parameter status. These features allow the ET to be a useful tool for troubleshooting.
The CAT ET will connect to the machine service connector in order to communicate with the electronic control modules over the data link. The service connector is located behind the access cover of the fuse panel in the right interior panel of the cab. For more information and the locations of the connectors, see Testing and Adjusting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine's Service Manual.
