The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of the ET.The Electronic Technician (ET) is not required in order to determine the diagnostic codes and the ET 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 ET. The ET can also display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow the ET to be a useful tool for troubleshooting.The ET connects to the machine diagnostic connector and the ET communicates with the electronic control modules over the data link. The diagnostic connector is located by the fuse panel. For more information and the locations of the connectors, see Troubleshooting, "Electrical Components and Connector Locations" and the Electrical System Schematic in your machine's Service Manual.Connect the ET to the machine. Turn the key start switch to the RUN position. Start the ET. The ET will initiate communications with the electronic control modules on the machine. The ET will list the available electronic control modules on the machine after communication has been established.Tractor Status Groups For ETThe ET uses status groups in order to display information about the status of the parameters.
