737-700 MAINTENANCE TRAINING MANUAL
BUILT IN TEST - SELF-TEST MODE - VOR / MB / MMR / DME / RA / VHF COMM
A23-12-00-018.fm
General
The VOR/MB, MMR, DME, RA, and VHF transceiver has built-in test equipment (BITE). You start the test on the front of the LRU.
;When you start the test, the built-in test equipment examines the input from the control panel, the internal circuits and processors of the LRU, and the input/output to the antennas.
BITE Display - Normal Operating Mode
In normal operating mode, the display shows the part number and the software version of the LRU.
The normal-operating-mode display comes on at these times:
-During the normal operation of the LRU
-When you push the switch next to RETURN on any other page
-Five minutes after you push either switch on the front panel.
BITE Display - Test
From the normal-operating-mode display, push either switch to start the test. The LRU starts the test. The display shows TEST IN PROGRESS. Also, the display shows how much of the test is complete.
When the LRU stops the test, the display shows TEST COMPLETE. If there are no failures, the display shows NO FAILURES. If there are failures, the display shows FAILURES.
To see more about the failures, push the switch below WHY. The display shows the result of the LRU test:
--OK- means the LRU is good
-FAILED means the LRU is not good.
The display shows EXTERNAL FAILURES PRESENT if the control panel input or the antenna system are not good.
To see specific information about external failures, push the switch below MORE.
When you push the switch next to MAINT, the display shows information about the status of the LRU and its inputs. The first status page shows the status of the LRU. Other status pages show the status of the tuning input, discrete inputs, program pins, and the central maintenance computer input.
NOTE: The LRU always shows INACTIVE for the status of the central maintenance computer. This is because the LRU has no input from a central maintenance computer on SWA airplane.
