Connections for the Communication Adapter Group and the Cat Electronic Technician (ET)
The components needed for use of the Communication Adapter Group and the Cat Electronic Technician ( ET) to determine diagnostic codes are listed below:
(1) Current version of Cat ET software
(2) 317-7484 Communication Adapter Group
(3) Service diagnostic cable.
(4) Cable Note: Cat Electronic Technician (Cat ET) and VIMSpc are service tools designed to run on a personal computer (PC) under Microsoft WindowsVIMSpc can access all the VIMSTM information for the machine.Cat ET is used to communicate to the electronic control module (ECM) over the data link by connecting to the machine diagnostic connector. For more information about connectors, see Troubleshooting, "Electrical Components and Connector Locations"VIMSpc is a software tool used to analyze data downloaded from a machine. VIMSpc does not need to connect to a machine. VIMSpc can be used to generate reports that provide historical records of the operating conditions for the machine. The operating conditions represent the work environment as well as the operating parameters of the machine in the work environment. These reports can be used to monitor trends in the work environment and machine operation. Reference: See Special Publication, NEHS0758, "Communications Adapter II User's Manual Contains Software".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 the Cat ET.Cat ET is not required to determine diagnostic codes and Cat ET is not required to clear the diagnostic codes. However, the process of determining the diagnostic codes is easier and faster by using the Cat ET. The 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, see Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in the Service Manual of your machine.For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531.
