View the active diagnostic codes and logged diagnostic codes.
View the active event codes and logged event codes.
View the status of parameters.
Clear active and logged diagnostic codes.
Perform calibrations of machine systems.
Program (Flash) the ECM with the "WINflash" program. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".
