(3) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(4) Operate the sidestick for ailerons, spoilers and elevators at full travel for 5 min.
(5) Operate the rudder pedals at full travel for 5 min.
(6) Operate the flap and slat control lever at full travel for 5 min.
4. Fault Isolation
_______________
A. If the test gives:
-the message HYD Y RSVR OVHT on the upper ECAM DU,
-the PTU P/BSW FAULT light on panel 40VU,
-the YELLOW ENG 1 PUMP P/BSW FAULT light on panel 40VU,
-the OVHT flag on the HYD page of the lower ECAM DU:
- measure the temperature with a temperature sensor adjacent to the XMTR-TEMP, Y RSVR (3381GR).
(1) If the temperature is more than 95 +2.2 -2.2 deg.C (203.00 +3.96 -
3.96 deg.F):
- do a check of the internal leakage of the Yellow hydraulic system (Ref. AMM TASK 29-00-00-280-003).
NOTE : Make sure that the cargo door selector of the AFT cargo door
____ is not jammed in the OPEN or CLOSE position.
(a) Do a check for local increase of the temperature and unusual noise specially at the subsequent components. Replace the components as necessary.
1 CHECK VALVE- ELEC PUMP DELIVERY, Y (3083GM) (Ref. AMM TASK 29-
_
24-21-000-001).
a Do a visual inspection of the CHECK VALVE- ELEC PUMP
_ DELIVERY, Y (3083GM) for damage and missing parts.
b If parts are missing, do the susequent before you install
_ the new check valve:

- Examine the Yellow HP filter (3048GM) (Ref. AMM TASK 29-13-45-610-001) and the Yellow HP manifold (Ref. AMM TASK 29-13-14-000-001) and (Ref. AMM TASK 29-13-14-400-001) to find these parts.
c Install the CHECK VALVE- ELEC PUMP DELIVERY, Y (3083GM)
_ (Ref. AMM TASK 29-24-21-400-001).
2 RELIEF VALVE-HP, Y (3063GM) (Ref. AMM TASK 29-13-32-000-001)
_ and (Ref. AMM TASK 29-13-32-400-001).
3 FILTER-RSVR RETURN, Y (3002GM) (Ref. AMM TASK 29-13-44-610-
_
001).
4 FILTER-HP, Y (3048GM) (Ref. AMM TASK 29-13-45-610-001).

5 CHECK VALVE-HP FILTER, Y (3059GM) (Ref. AMM TASK 29-00-00-910-
_ 003). R
R 6_CHECK VALVE-HP MANIFOLD RETURN, Y (3022GM) (Ref. AMM TASK 29-00-00-910-003).
R 7_ RELIEF VALVE-BRK SYS, Y (3067GM) (Ref. AMM TASK 32-44-15-000-R 001) and (Ref. AMM TASK 32-44-15-400-001).
(b) If the internal leakage is more than permitted:
- examine the system to find the defective component,
- replace or repair the defective component.
(c) If the internal leakage is not more than permitted:
- do a check of the filter elements of the FILTER-ENG 2 PUMP CASE DRAIN, Y (3084GM) , FILTER-HP, Y (3048GM) and FILTER- RSVR RETURN, Y (3002GM).
(d) If the filter elements are dirty:
- replace the filter element (Ref. AMM TASK 29-13-43-610-040) or (Ref. AMM TASK 29-13-44-610-001) or (Ref. AMM TASK 29-13-45-610-001)
(2) If the temperature is less than 95 +2.2 -2.2 deg.C (203.00 +3.96 -
3.96 deg.F):
- do a check for continuity between: XMTR-TEMP, Y RSVR (3381GR) connector A/A and connector A/B (Ref. ASM 29-33/01).
(a) If there is continuity:
- replace the XMTR-TEMP, Y RSVR (3381GR) (Ref. AMM TASK 29-33-11-000-003) (Ref. AMM TASK 29-33-11-400-003).

(b) If there is no continuity:
- make sure that the wiring is not connected to GND between: XMTR-TEMP, Y RSVR (3381GR) connector A/B and the RELAY-Y RSVR OVHT FAULT (3705GD) connector Z (Ref. ASM 29-33/01) and (Ref. ASM 29-13/01).
1 If the wiring is connected to GND:
_ - repair the wiring as necessary.
(c) If the fault continues:
- make sure that the wiring is not connected to GND between: XMTR-TEMP, Y RSVR (3381GR) connector A/B and the SDAC-1 (1WV1) connector 4G (Ref. ASM 29-33/01).
1 If the wiring is connected to GND:
_ - repair the wiring as necessary.
(d) If the fault continues:
- make sure that the wiring is not connected to GND between: XMTR-TEMP, Y RSVR (3381GR) connector A/B and the SDAC-2 (1WV2) connector 4G (Ref. ASM 29-33/01).
