Connections for the Communication Adapter II and the Cat ET The components that are needed to use the Communication Adapter II and the Cat ET 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 a personal computer | |
Reference: Refer to Special Publication, NEHS0758, "Communications Adapter II User Manual Contains Software".
Note: Cat ET is a software program that can be used on a 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 the Cat-ET.
Cat ET is not required to determine the diagnostic codes. Cat ET is required to clear the diagnostic codes. However, the process of determining the diagnostic codes is easier and faster by 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 the Cat ET to be a useful tool for troubleshooting.
The Cat ET 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, refer to Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine Service Manual.
For instructions on servicing Sure Seal connectors, refer to Special Instruction, SMHS7531. For instructions on servicing Deutsch DT connectors, refer to Special Instruction, SEHS9615.
Use the digital multimeter for making continuity checks 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 3-pin DT breakout. The adapter cable is used for measurements in the sensor circuits.
Except for harness tests, the use of certain test equipment is not recommended for use on modern Caterpillar electrical circuits. Such testers include the following examples: the 8T-0500 Continuity Tester and 5P-7277 Voltage Tester.
Note: A procedure has been developed to test "In Cylinder" Position Sensors. Reference Special Instruction REHS7338, "Procedure to Test the Position Sensor of a Hydraulic Cylinder".
