Launch the FADEC Level I Diagnostic application and follow the onscreen prompts.
RESULT: The Diagnostic software guides the user through the engine start sequence,
specific engine RPM settings, and the ECU power and channel check. The interactive
software prompts the user, at predetermined intervals, to adjust control settings and
allow the software to collect engine operational data through various profiles. As test
sequences increment, the software records the data. During engine operation, the
diagnostic software monitors and displays the engine operational status in comparison
to the expected results. On-screen displays are color-coded to identify pass/fail status
at a glance. At the completion of the test sequence, the Level I Diagnostic software
compiles a report of the diagnostic test for on-screen review or printout.
