737-600/700/800/900 AIRCRAFT MAINTENANCE MANUAL
General
The FDAU has built-in test equipment (BITE) and self-test
software. BITE does these functions:
* Causes the fault lights to come on
* Shows the failure codes
* Holds fault messages.
PCMCIA Drive and Cards
The FDAU also has two slots for Personal Computer Memory
Card International Association (PCMCIA) cards. You can put a
card in either slot. To eject the card, push the eject switch above
the card. The PCMCIA cards can do these functions:
* Load software into the FDAU
* Store FDAU data.
To load software, put the card with the software in either
PCMCIA slot. The FDAU turns on the IN PROG LED. When the
transfer is complete, the FDAU turns on the XFER COMP LED.
You can remove the card. If the software transfer fails, the FDAU
turns on the XFER FAIL LED. To transfer data to a data card, put
a formatted card in either slot and lower the card holder arm.
The DFM BITE LED comes on if the PCMCIA drive fails.
Fault Lights
The FDAU has these three failure indicator lights on the front
panel:
* ACMS
* DFDR
* DFDAU.
The ACMS light comes on with input faults, DMU master
controller faults, or mass memory faults. The FDAU continues to
send data and the FDR continues to store data.
The DFDR FAIL light comes on with a fault in the FDR. The
FDAU continues to send data to the FDR.
The DFDAU failure light comes on with a power supply fault,
output data fault or erasable programmable read only memory
(EPROM) fault in the FDAU. The EPROM holds the program for
the FDAU. The FDAU does not send data to the FDR.
BITE Fault Code Display
A seven-digit alphanumeric display shows fault codes if there is
a fault in the FDAU. A three-position BITE toggle switch controls
the fault code display. Set this switch to the left or right position
to do the test. The spring loaded center position is off.
Move the switch to the right to start a FDAU test. You see these
indications:
