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).

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) Do the operational test of the Green hydraulic system (Ref. AMM TASK 29-11-00-710-001).
(5) 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 content indication shows high fluid level on the lower ECAM DU, or
- The content indication shows low fluid level on the lower ECAM DU, or
- The content indication fluctuates between high and low fluid level on the lower ECAM DU after pressurization of the hydraulic system during the operational test, or the subsequent warnings come into view:
- The HYD G ENG 1 PUMP LO PR on the upper ECAM DU,
- The LO flag of the Green hydraulic system on the HYD page of the lower ECAM DU,
- The Green ENG 1 PUMP P/BSW FAULT on panel 40VU,
- Do a visual check of the fluid quantity shown on the mechanical indicator (1834GQ) on the ground service panel of the Green hydraulic system.
- Do a visual check of the fluid quantity shown on the fluid content indicator of the Green reservoir.
- Do a check of the pressure of the Green system accumulator (1070GM) (Ref. AMM TASK 29-10-00-200-003).
- Do a check of the pressure of the Green hydraulic reservoir (Ref. AMM TASK 29-10-00-200-002).
(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).
