Connections for the Electronic Technician (ET) The components that are needed in order to use the CAT Electronic Technician in order to determine diagnostic codes are listed: (1) An IBM-COMPATIBLE personal computer with an installed current version of Caterpillar Electronic Technician software (2) 139-4166 Data Link Cable or 7X-1570 Data Link Cable (3) 7X-1425 Cable and 4C-6805 Adapter (4) Special Publication, JEBD3003, Special Publication, JERD2124, Special Publication, JERD2129 ; Caterpillar Electronic Technician software (5) 7X-1700 Communication Adapter Tool with Special Publication, NEXG4323, "Communications Adapter Software" | |
Note: Caterpillar Electronic Technician (ET) is a software program that can be used on an IBM compatible personal computer.
In order to use the Caterpillar Electronic Technician (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 Electronic Technician (ET) is not required in order to determine the diagnostic codes and the 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 ET. The ET can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow the ET to be a useful tool for troubleshooting.
The ET connects to the machine diagnostic connector and the 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 Testing and Adjusting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine's Service Manual.
Connect the ET to the machine. Turn the key start switch to the RUN position. Start the ET. The ET will initiate communications with the electronic control modules on the machine. The ET will list the available electronic control modules on the machine after communication has been established.
