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 content indication shows high fluid level on the lower ECAM DU:
 - 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 Blue reservoir.

 - Do a check of the pressure of the Blue system accumulator (Ref. AMM TASK 29-10-00-200-005).

 - Do a check of the pressure of the Blue hydraulic reservoir (Ref. AMM TASK 29-10-00-200-002).

 (1) If the three hydraulic fluid quantity indicators show different quantities and the pressures of the accumulator and the reservoir are correct:

 (a) Do the troubleshooting of the quantity indication system (Ref. TASK 29-12-00-810-803).

 (2) If the three hydraulic fluid quantity indicators show high level and the pressures of the accumulator and the reservoir are correct:

 (a) Drain the hydraulic fluid until you have the correct fluid quantity in the reservoir (Ref. AMM TASK 29-10-00-680-003).

 (b) Pressurize the reservoir of the Blue hydraulic system (Ref. AMM TASK 29-14-00-614-002).

 (3) If the three hydraulic fluid quantity indicators show high level, the pressure of the accumulator is correct, but the reservoir pressure is less than the permitted tolerance:
 (a) Do a check for external gas leaks on the reservoir and repair the defective components as necessary (Ref. AMM TASK 29-10-00-200-002).

 (b) If you find no external gas leaks, or the fault continues: 1 Do the troubleshooting for the loss of the reservoir

_ pressurization (Ref. TASK 29-12-00-810-801).
 2 Drain the hydraulic fluid until you have the correct fluid
_ quantity in the reservoir (Ref. AMM TASK 29-10-00-680-003).
 3 Pressurize the reservoir of the Blue hydraulic system (Ref.
_
 AMM TASK 29-14-00-614-002).

 4 After 5 minutes, read the gage of the fluid quantity indicator
_
 of the Blue reservoir.

 a If the difference of the fluid quantity is not more than 1
_
 liter:

 - No further actions are necessary. b If the difference of the fluid quantity is more than 1
_
 liter:

 - Do the bleeding procedures of the Blue hydraulic system (Ref. AMM TASK 29-00-00-870-008) and (Ref. AMM TASK 29-00-00-870-009).
 (c) If the fault continues: 1 Do the troubleshooting procedure (Ref. TASK 29-12-00-810-818).
_

 (4) If the three hydraulic fluid quantity indicators show high level, the pressure of the reservoir is correct, but the accumulator pressure is less than the permitted tolerance:
 (a) Do the troubleshooting procedure (Ref. TASK 29-12-00-810-818).
 B. Do the procedure as given in Para. 3. B. to make sure that the operation of the hydraulic quantity indication is correct.

________

 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).
