3. Fault Confirmation
__________________
NOTE : Continue with the step B. when the crew reported that the HYD B ELEC
____ PUMP LO PRESS warning was shown for a short time during the start of the engines.
A. Do the operational test of the Blue hydraulic system (Ref. AMM TASK 29-12-00-710-001).
B. Do the subsequent test when the HYD B ELEC PUMP LO PRESS warning was shown for a short time during the start of the engines.
(1) Start the engine No. 2 (Ref. AMM TASK 71-00-00-710-003).
(2) Start the engine No. 1 (Ref. AMM TASK 71-00-00-710-003).
(3) Look at the upper ECAM DU for the warning HYD B ELEC PUMP LO PRESS.
(4) Shutdown the engines (Ref. AMM TASK 71-00-00-710-028).
4. Fault Isolation
_______________
R A. If the test gives:
R - the HYD B ELEC PUMP LO PR on the upper ECAM DU,
R - the LO flag of the BLUE hydraulic system on the HYD page of the lower
R ECAM DU,
R - the BLUE ELEC PUMP P/BSW FAULT on panel 40VU,
R do the subsequent steps:
R - examine if the Blue electric pump operates.
R (1) If the ELEC PUMP-B (2075GJ) operates:
R - look on the ECAM SD - DU and do a check of the pressure indication:
R (a) If the pressure is less than 1450 psi (99.9739 bar):
R 1_ Do a check of the nitrogen charge pressure of the Blue
R hydraulic power accumulator (Ref. AMM TASK 29-10-00-200-008).
R a_ If necessary, replace the ACCU-B PWR (2070GM) (Ref. AMM
R TASK 29-12-42-000-001) and (Ref. AMM TASK 29-12-42-400-R 001).
R 2_ If the fault continues:
R a_ Replace the ELEC PUMP-B (2075GJ) (Ref. AMM TASK 29-12-51-R 000-001) and (Ref. AMM TASK 29-12-51-400-001).
R NOTE : Replace the ELEC PUMP-B (2075GJ) with the ELEC
____ R PUMP-Y (3075GX) which is interchangeable, if a new R pump is not available (Ref. AMM TASK 29-24-51-000-R 001) and (Ref. AMM TASK 29-24-51-400-001).

R (b) If the pressure is more than 1450 psi (99.9739 bar):
R - do a check for continuity between:
R PRESS SW-ELEC PUMP, B (2074GJ) connector A/A and connector A/C
R and repair the wiring as necessary (Ref. ASM 29-12/01).
R 1_ If there is continuity:
R - replace the PRESS SW-ELEC PUMP, B (2074GJ) (Ref. AMM TASK
R 29-12-17-000-001) and (Ref. AMM TASK 29-12-17-400-001).
R 2_ If there is no continuity:
R - do a check of the wiring for a GND connection between:
