Connections for the Communication Adapter Gp and Caterpillar Electronic Technician (Cat ET)The components that are needed to use the Communication Adapter 3 and Cat ET to determine diagnostic codes are listed: (1) Current version of Cat ET software and an IBM-COMPATIBLE personal computer (2) 317-7484 Communication Adapter Gp (3) Service diagnostic cable (4) CableReferenceRefer to Tool Operating Manual, NEHS1032, "317-7484 Communications Adapter 3".Note: Cat ET is a software program that can be used on an IBM compatible personal computer. In order to use 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 Cat ET.Cat ET is not required to determine the diagnostic codes and Cat ET is not required to clear the diagnostic codes. However, the process of determining the diagnostic codes is easier with Cat ET. Cat ET can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow Cat ET to be a useful tool for troubleshooting.Cat ET is used to communicate to the electronic control module over the data link by connecting to the diagnostic connector. For more information and the locations of the connectors, Refer to Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your vehicles Service Manual.For instructions on servicing Sure Seal connectors, refer to Special Instruction, SMHS7531. For instructions on servicing Deutsch connectors, refer to 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, refer to 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, using continuity testers such as the 8T-0500 Continuity Tester or voltage testers such as the 5P-7277 Voltage Tester is not recommended for today's Caterpillar electrical circuits.
