Connections for the Communication Adapter II (or Communication Adapter III) and the Electronic Technician (ET)The components needed for the Communication Adapter II (or Communication Adapter III) and the Cat ®Electronic Technician to determine diagnostic codes are listed below: (1) Cable (2) 171-4400 Communication Adapter II (3) Service diagnostic cable. (4) Current version of Cat Electronic Technician software and a personal computerReferenceSee Special Publication, NEHS0758, "Communications Adapter II User Manual Contains Software".Note: Cat Electronic Technician (ET) is a software program that can be used on an IBM compatible personal computer. To use the Cat 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 to determine diagnostic codes. The ET is also not required to clear diagnostic codes. However, the process of determining the diagnostic codes is easier and faster using ET. ET can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow ET to be a useful tool for troubleshooting.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 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 measuring resistance or for measuring voltage. For instructions about the use of the 6V-7070 Digital Multimeter , see Special Instruction, SEHS7734. The 7X-1710 Multimeter Probe measures 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 with three pins. The adapter cable is used for measurements in the sensor circuits.Note: Except for harness tests, tools such as the 8T-0500 Continuity Tester , or the 5P-7277 Voltage Tester , are not recommended for today's Cat electrical circuits.
