Test A l l Table
U s e tab le 7-6 to h e l p dete r m i ne the fai l u re after ru n n i ng the Test A l l d i agnostic or any
i nd ivid ual self-tests. The tab le I ists the self-tests in the order the Test A l l d i agnostic executes
them. A pass message indicates the assemb l ies and subblocks tested are probably operati ng
correctly. The pass/f a i l messages are l isted on the vertical axi s of the tab le. T he assembl ies
and subblocks tested o r used by the self-tests are l isted on the horizontal axi s of the tab le.
(Refer to the i ntrodu ction of paragrap h 7-7 for the l ist of asse m b l ies not tested by Test A l l .)
There are two sym b o l s used i n tab le 7-6:
tab le, the assem bly or subblock is used in the test but is not a l i kely cause of the fai l u re .
When the sym bol "X" is used i n the tab le, the asse m b ly or s u b b lock is probably the cause
of the fai l u re. No symbol means the assem bly or s u bb l ock is not u sed i n the test.
