Connections for the Communication Adapter II and the Electronic Technician (ET)The components that are needed in order to use the Communication Adapter II and the CAT Electronic Technician for the determination of the diagnostic codes are listed: (1) Cable (2) 171-4400 Communication Adapter II (3) Service diagnostic cable. (4) Current version of Caterpillar Electronic Technician 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 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.For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For service instructions about the Deutsch "DT" Type connectors, see Special Instruction, SEHS9615.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 Electronic Technician (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 Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine's Service Manual.For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For instructions on servicing Deutsch connectors, see Special Instruction, SEHS9615.Use the digital multimeter for making continuity checks or for measuring voltage. For instructions about the use of the Digital Multimeter, see the owners manual that is provided with the multimeter. The 7X-1710 Multimeter Probe is used to measure the voltage at the connectors without disconnecting the connectors. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a breakout (3 pin). The adapter cable is used for measurements in the sensor circuits.Note: Except for harness tests, using continuity testers
