(e) If the fault continues:
- do the operational test of the central warning system (Ref. AMM TASK 31-50-00-710-001).
1 If the test gives the maintenance message SDAC1 : Y HYD TEMP
_
XMTR 3381GR:
- replace the SDAC-1 (1WV1), (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
2 If the test gives the maintenance message SDAC2 : Y HYD TEMP
_
XMTR 3381GR:
- replace the SDAC-2 (1WV2), (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
B. If the test gives:
-No messages on the upper and lower ECAM DU,
-No FAULT lights on the panel 40VU:
(1) Do the operational test of the VALVE-Y PUMP FIRE, ENG 2 (3046GD) (Ref. AMM TASK 29-10-00-710-001).
NOTE : If the VALVE-Y PUMP FIRE, ENG 2 (3046GD) is not in the fully
____ open position, this can be the cause of an overheat of the hydraulic system.

(2) If the operational test gives an unsatisfactory operation of the VALVE-Y PUMP FIRE, ENG 2 (3046GD), replace the VALVE-Y PUMP FIRE, ENG 2 (3046GD):
- (Ref. AMM TASK 29-13-52-000-001) and
- (Ref. AMM TASK 29-13-52-400-001).
(3) Do a check of the engine pump for a possible cavitation condition (Ref. AMM TASK 29-00-00-280-006).
NOTE : A cavitation condition of the engine pump is possible when the
____ engine pump operates with the engine pump fire valve closed (if you set the ENG 1 (2) FIRE pushbutton on the Eng/APU fire panel), or with the reservoir below the low level (ECAM indication).
C. When the VALVE-Y PUMP FIRE, ENG 2 (3046GD) was not the cause of the
malfunction:
- Do the test as given in Para. 3. B. to make sure that operation is correct (no message shown).
5. Close-up________
A. Aircraft Maintenance Configuration
(1) Make sure that the Yellow hydraulic system is de-pressurrized (Ref. AMM TASK 29-24-00-864-001).
(2) Make sure that the aircraft electrical circuits are de-energized (Ref. AMM TASK 24-41-00-862-002).
