Connections for the Communication Adapter III and the Caterpillar Electronic Technician (Cat ET) service tool The components that are needed in order to use the Communication Adapter II and the Cat ET service tool in order to determine diagnostic codes are listed: (1) Cable (2) 317-7484 Communication Adapter Gp (3) Service diagnostic cable. (4) Current version of Cat ET software and an IBM-COMPATIBLE personal computer | |
Reference: See Special Publication, NEHS1032, "Communications Adapter III Users Manual Contains Software".
Note: The Caterpillar Electronic Technician (Cat ET) service tool is a software program that can be used on an IBM compatible personal computer.
In order to use the Cat ET service tool, order the following materials: Special Publication, JERD2124, "ET Single Use Program License", Special Publication, JEHP1026, "Information and Requirements Sheet", 327-8981 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 service tool.
The Cat ET service tool is not required in order to determine the diagnostic codes and the Cat ET service tool 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 Cat ET service tool. The Cat ET service tool can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow the Cat ET service tool to be a useful tool for troubleshooting.
The Cat ET service tool 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 Schematic in your machines 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 257-9140 Digital Multimeter for measuring resistance and for measuring voltage. Verify that the 257-9140 Digital Multimeter is calibrated before use.
The 7X-1710 Multimeter Probe are 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 151-6320 Removal Tool is used to remove a wire, a socket, or pin from the connector body.
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.
