3. Fault Confirmation
__________________
A. Make sure that this(these) circuit breaker(s) is(are) closed:

B. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(3) On the ECAM control panel on the center pedestal, push the HYD pushbutton switch. Make sure that the HYD page is shown on the system display of the ECAM.
(4) Look for fault indications on the upper ECAM DU, the lower ECAM DU and panel 40VU.
4. Fault Isolation
_______________
A. If the Fault Confirmation gives:
- the message HYD B RSVR LO LVL on the upper ECAM DU
- the contents indication (shows low-fluid level) on the lower ECAM DU in amber,
- the BLUE ELEC PUMP P/BSW FAULT on panel 40VU,
- the single chime and the MASTER CAUT lights come on:
- do a visual check of the quantity shown on the mechanical indicator of the Blue reservoir.
(1) If the quantity shown is more than or equal to 2.4 l (0.6340 USgal):
- do a check for 28 VDC between: LOW LEVEL SWITCH connector B/A and connector B/C (Ref. ASM 29-31/02).
(a) If there is no 28 VDC:
- do a check of the wiring between: LOW LEVEL SWITCH connector B/C and CB (1832GQ) and repair the wiring as necessary (Ref. ASM 29-31/02).
(b) If there is 28VDC:
- replace the LOW LEVEL SWITCH (Ref. AMM TASK 29-12-41-000-003) and (Ref. AMM TASK 29-12-41-400-003).
