Connections for the Communication Adapter II and ETThe components that are needed in order to use the Communication Adapter II and Cat 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 (Cat 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 Cat ET.Cat ET is used to communicate to the systems components over the data link by connecting to the machine service connector.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 3 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.Caterpillar Electronic Technician
Cat ET is used in order to troubleshoot the "Electrohydraulic" (E/H) controls and remote switches. Cat ET is also used to display the AccuGrade sensor data.The Cat ET is a software program that is used to access data. The service technician will use the Cat ET in order to perform the maintenance on the machine. Some of the options that are available with the Cat ET are listed below:
Diagnosis of problems
Viewing diagnostic codes
Viewing active event codes and logged event codes
View the status of parameters.
Clear active diagnostic codes and clear logged diagnostic codes
Perform calibration of machine systems.
Program the ECM (Flash). This is done with the "WINflash" program. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".
Print reports.See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes". Diagnostic information is accessed with the following drop down menus:
Active diagnostic codes
