If the test gives that the APU supplies
. no bleed-air pressure
or
. low or fluctuating bleed-air pressure:
-do the related trouble shooting task (Ref. TASK 49-00-00-810-937).
(3)
If the fault continues:
-replace the APU BLEED P/BSW (5HV) on panel 30VU.
(4)
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).
(5)
If the fault continues:
-do a check and repair the wiring if necessary between: the BMC-1, BMC-2 connector AA/14C and the APU BLEED P/BSW (5HV) connector A/B1 (Ref. ASM 36-12/00), the APU BLEED P/BSW (5HV) connector A/B3 and GND (Ref. ASM 36-12/00).
