B. Maintenance Action
(1)
If the test gives the Warning AIR APU FAULT on the EWD:
-do the trouble shooting of the APU bleed-air output (Ref. TASK 49-00-81-810-856).
(2)
If the fault continues:
-replace the APU BLEED P/BSW (5HV) on panel 30VU.
(3)
If the fault continues:
-do a check and repair if necessary the wiring between: the BMC-1, BMC-2 connector AB/6A and the ECB (ELECTRONIC CONTROL BOX) (59KD) connector AB/D6 (Ref. ASM 36-12/00).
