Connections for the Communication Adapter II and the Caterpillar Electronic Technician (ET)The components that are needed in order to use the Communication Adapter II and the Caterpillar Electronic Technician ( ET) in order to determine diagnostic codes are listed: (6) Cable (7) 171-4400 Communication Adapter II (8) Service diagnostic cable. (9) Current version of Cat ET software and an IBM-COMPATIBLE personal computerReferenceSee Special Publication, NEHS0758, "Communications Adapter II User's Manual Contains 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 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 Cat 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 is used to communicate to the electronic control module over the data link by connecting to the machine diagnostic connector. For more information and the locations of the connectors, see Testing and Adjusting, "Location of Electrical Components" and the Electrical System Schematic in your machine's Service Manual.Connecting Caterpillar Electronic Technician
