5.3.1 FE Utility
In addition to the diagnostic console display and the LED code, the FE utility
dumps the diagnostic state to the console (Example 5–12). This state indicates
the major and minor test code of the test that failed, the 10 parameters
associated with the test, and additional diagnostic state information.
