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) Pressurize the Yellow hydraulic system with the electric pump (Ref. AMM TASK 29-24-00-863-001).
(5) Look for fault indications on the upper ECAM DU, the lower ECAM DU and panel 40VU.
(6) Depressurize the Yellow hydraulic system (Ref. AMM TASK 29-24-00-864-001).
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 Yellow hydraulic system with the electric pump, or the subsequent warnings come into view:
- The HYD Y ELEC PUMP LO PR on the upper ECAM DU,
- The LO flag of the Yellow hydraulic system on the HYD page of the lower ECAM DU,
- The Yellow ELEC 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 Yellow reservoir.
- Do a check of the pressure of the Yellow system accumulator (3070GM) (Ref. AMM TASK 29-10-00-200-003).
- Do a check of the pressure of the Yellow hydraulic reservoir (Ref. AMM TASK 29-10-00-200-002).
