run automatically and consecutively, unless a fault occurs. Some tests display additional
prompts requiring your response. EST prompts (informational prompts and those
requiring your response) are listed in Table 3-6.
At the end of each test, the test’s name and pass/fail/fault status are displayed. If an EST
test does not pass, you may still continue EST execution, although the entire EST will not
pass until the error conditions are corrected.
