 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).
