The Caterpillar Electronic Technician (ET) is a software program that is used to access data. The service technician can use the Caterpillar Electronic Technician in order to perform maintenance work on the machine. Some of the options that are available with the Caterpillar Electronic Technician are listed below:

• view Diagnostic codes. See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes".

• Viewing active event codes and logged event codes

• View the status of parameters.

• Clear active diagnostic codes and clear logged diagnostic codes

• Perform calibration of machine systems.

• Program the ECM (Flash). This is done with the "WINflash" program. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".

• Print reports.

The following list contains some of the diagnostic functions and programming functions that are performed by the service tools.
