(1) If the three hydraulic fluid quantity indicators show the same quantity, the pressure of the reservoir is correct, but the accumulator pressure is less than the permitted tolerance:
(a) Do a check for external gas leaks on the power accumulator and repair the defective components as necessary (Ref. AMM TASK 29-10-00-200-003).
(b) If you find no external gas leaks, or the fault continues:
1_ Replace the ACCU-Y PWR (3070GM) (Ref. AMM TASK 29-13-42-000-
001) and (Ref. AMM TASK 29-13-42-400-001).
2_ Do the bleeding procedures of the Yellow hydraulic system
(Ref. AMM TASK 29-00-00-870-004), (Ref. AMM TASK 29-00-00-870-
005), (Ref. AMM TASK 29-00-00-870-006) and (Ref. AMM TASK 29-
00-00-870-007).
B. Do the procedure as given in Para. 3. B. to make sure that the operation of the hydraulic quantity indication is correct.
5. Close-up
________
A. Put the aircraft back to the serviceable condition.
(1) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(2) De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).

3. Fault Confirmation
__________________
A. Do the operational test of the Yellow hydraulic system (Ref. AMM TASK 29-13-00-710-002).
4. Fault Isolation
_______________
A. If the test gives:
- the message HYD Y SYS LO PR on the upper ECAM DU,
- a system pressure indication of 3000 psi on the lower ECAM DU,
- an intermittent PTU indication in amber on the lower ECAM DU:
(1) Do the ground scanning of the AFS (Ref. AMM TASK 22-91-00-710-001).
(a) If the ground scanning shows the messages:
- AFS: HYD 3151GN
- AFS: ELAC
- SFCC 2: WRONG INHIBIT SIGN FROM CARGO DOOR YELLOW SYSTEM
- replace the TIME RELAY (3816GX).
B. Do the fault confirmation procedure as given in Para. 3. to make sure that the operation is correct.
