To do the existing faults report, do these steps: * Go to the main menu * Use the up or down arrow switches until you see EXISTING FAULTS? in the BITE display * Push the YES switch. If the test passes, the display shows NO FAULTS. If the test fails, the display shows a fault message. You can use the switches on the BITE panel to see more information about the fault message. You can also see if there are other fault messages. If there is one or more existing fault, the first message shows the dispatch status of the airplane. The message NO DISP FAULT is for one or more non-dispatchable fault. The message DISPATCH FAULT is for one or more dispatchable fault. PSEU Fault Messages Each PSEU fault message has a single maintenance action. The fault message has a BITE message number. This is the format for the BITE message numbers: * Eight characters in length * The first two characters are the ATA chapter number of the system * The third character is a hyphen (-) * The fourth character is the first number of the ATA section number of the faulted sub-system. The last four digits show the fault: * 0XXX - power faults * 1XXX - sensor faults * 2XXX - discrete input faults * 3XXX - report faults * 4XXX - others * 5XXX - inputs that have no cycles (TOW and SPDBRK tests) * 6XXX - field programmable gate array (FPGA) output load faults. PSEU Status Messages The PSEU shows these status messages for these conditions: * Message 32-04001 - AIR/GND OVERRIDE shows that the PSEU outputs are in the override condition (this is not a fault). * Message 32-64001 - INTERNAL FAULT shows that there is a fault internal to the PSEU. * Message 32-64002 - TEST NOT COMPLETE shows that a test on the PSEU was interrupted. * Message 32-64003 - DISPATCH FAULT shows that there is an existing dispatch type fault and the PSEU light can be turned off. * Message 32-64004 - NO DISP FAULT shows that there is an existing no dispatch type fault and the fault must be corrected to turn off the PSEU light.

The PSEU shows these status messages when a problem exists with the flight recorder and the mach airspeed warning module for these conditions: * Message 32-66007 - DISPATCH 1 FAULT shows that the PSEU does not sense the expected load on the DISPATCH FAULT A output. * Message 32-66010 - NO DISP 1 FAULT shows that the PSEU does not sense the expected load on the NO DISPATCH FAULT A output. * Message 32-66017 - DISPATCH 2 FAULT shows that the PSEU does not sense the expected load on the DISPATCH FAULT B output. * Message 32-66020 - NO DISP 2 FAULT shows that the PSEU does not sense the expected load on the NO DISPATCH FAULT B output. More Details MORE DETAILS? shows this information for the fault message: * LATCHED YES or NO * Connector and pin number. LATCHED shows if the fault is latched. Faults that only occur when the airplane is in the air are latched so you can see them when you do the EXISTING FAULTS test on the ground. The connector and pin number message shows that information www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：737NGAMM7
