(1) Depressurize the Green, Yellow and Blue hydraulic systems, but not the reservoirs (Ref. AMM TASK 29-00-00-864-001).
(2) Put the warning notices in position to tell persons not to pressurize the hydraulic systems:
- in the flight compartment on the hydraulic section 40VU of the overhead panel,
- on the ground service panels of the Green, Yellow and Blue hydraulic systems.
(3) Open the access doors 196BB and 197FB.
(4) Open the right main door of the main landing gear (Ref. AMM TASK 32-12-00-010-001).
(5) Read the pressure gages (1383GM, 2383GM, 3383GM) on each hydraulic reservoir.
(6) If the reservoir pressure indication is more than 52 +2 -2 psi (3.5852 +0.1378 -0.1378 bar):
(a) Do the functional test of the pressurizing system of the hydraulic reservoirs (Ref. AMM TASK 29-14-00-720-001).
4. Fault Isolation
_______________
A. If the reservoir pressure increases during the test to more than 50 +2 -2 psi (3.4473 +0.1378 -0.1378 bar):
(1) Replace the PRESSURE REDUCING VALVE (Ref. AMM TASK 29-14-43-000-001) and (Ref. AMM TASK 29-14-43-400-001).
(2) Take a fluid sample from each hydraulic system to make sure that the contamination of the hydraulic fluid is in the approved values (Ref. AMM TASK 12-32-29-281-001).
B. Do the functional test of the pressurizing system of the hydraulic reservoirs again to make sure that the function is correct (Ref. AMM TASK 29-14-00-720-001).
5. Close-up
________
A. Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s): 2701GJ, 2702GJ, 3801GX, 3802GX, 3803GX

A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) On the overhead panel 40VU, look for the FAULT light of the YELLOW/ENG 2 PUMP P/BSW.
4. Fault Isolation
_______________
A. If the Fault Confirmation gives:
- the YELLOW/ENG 2 PUMP P/BSW FAULT on panel 40VU:
- replace the BOARD-ANN LT TEST & INTFC (20LP) (Ref. AMM TASK 33-14-33-000-001) and (Ref. AMM TASK 33-14-33-400-001).

(1) If the fault continues:
- do a check and repair the wiring between the: BOARD-ANN LT TEST & INTFC (20LP) pin A/10 and the P/BSW-HYD/YELLOW/ENG 2 PUMP (3703GD) pin A/7 (Ref. ASM 33-14/22).
B. Do the operational test of the annunciator light test system (Ref. AMM
TASK 33-14-00-710-001) to make sure that the operation is correct.
5. Close-up
________
A. De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
