The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of Cat-ET.Cat-ET is not required in order to determine the diagnostic codes. The Cat-ET is also not required in order to clear the diagnostic codes. However, the process of determining the diagnostic codes is easier and faster by using 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 with electronic control modules over the data link, by connecting to the machine diagnostic connector.
