Connections for the Communication Adapter Gp and Cat® 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 a laptop computer (2) 538-5051 Communication Adapter Gp (3) Service diagnostic cable (4) Cable | |
Reference: Refer to Tool Operating Manual, NEHS1032, "538-5051 Communications Adapter 3".
Note: Cat® ET is a software program that can be used on an IBM compatible personal computer.
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. 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 modern Caterpillar electrical circuits.
