Connections for the Communication Adapter 3 and the Caterpillar Electronic Technician (ET) The components that are needed in order to use the Communication Adapter 3 and the Caterpillar Electronic Technician ( ET) in order to determine diagnostic codes are listed: (6) Cable (7) 317-7484 Communication Adapter 3 Group (8) Service connector diagnostic cable. (9) Current version of Cat ET software and an IBM-COMPATIBLE personal computer |
Reference: Refer to the Special Publication, NEHS0758, "Communications Adapter 3 User Manual ".
Note: Caterpillar® Electronic Technician (Cat® ET) service tool is designed to run on a personal computer (PC) under Microsoft Windows
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 the Cat ET.
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 when using the 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 circuits when connected to the machine diagnostic service connector.
For information on the locations of the machine harness wiring connectors, refer to the complete Machine 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.
The 7X-1710 Multimeter Probes are used to measure the voltage at the connectors without disconnecting the connectors. The probe ends are pushed into the back of the connector along the wire.
Note: Certain machine wiring harnesses on the D7E Track Type Tractor are sealed. The 7X-1710 Multimeter Probes cannot be used on these harnesses. The troubleshooting procedures that are listed in this manual will give instructions on when the probes can be used and when the probes cannot be used.
The operation of the power transistors and the transistor circuits should be tested using the Cat ET Automated Power Inverter Test when an internal problem is suspected to be present in the Power Inverter.
Refer to the Testing and Adjusting, "Power Inverter - Test" section of this manual for instructions on using this tool.
