DFCS BITE PAGES - CURRENT STATUS AUTOTEST
General
If all of the autotests pass, the next page that shows on the MCDU is the AUTOTEST PASSED page. You can then continue to the next page to select a channel to test.
If one or more of the autotests fail, you get the AUTOTEST FAILED page.
AUTOTEST FAILED Page
This page shows all of the systems that did not pass the autotest. You can get more data about the failure when you select the system. For the example, the operator selects the ADIRU, LSK 2L. This shows the STATUS SUSPECT LRU(S) page for the ADIRU autotest.
If you push LSK 6R, you go to the FAULT REVIEW page.
STATUS SUSPECT LRU(S) Page
This page shows the LRUs that could cause the failure of the ADIRU autotest. It also shows the connector pins of the FCC that were used to find this failure. You can use the NEXT PAGE and PREV PAGE function keys on the MCDU to look at all of the suspect LRUs.
If you want to look at more detail about the failure, select LSK 6L for test data.
Test Data Page
This page shows the test step where the failure was found and the results of the test. For the example, in the graphic, the first failure

occurs in the 5th step (Q005) of the test. The expected data should be a hex word 6000. FCC A failed since it shows a hex word of 0000, but FCC B passes. There was also a failure in step 7 (Q007). Again, FCC A failed and FCC B passed.
The Q before 005 and 007 means the failures occurred during the autotest. Q stands for quick test which is what the autotest used to be called.
You can use the NEXT PAGE and PREV PAGE function keys on the MCDU to look at all of the detail test data.
If you want to rerun the test, you push LSK 6L. If you push LSK 6R, PREV MENU prompt, you go to the AUTOTEST FAILED page.
