(d) If the fault continues:
- replace the QUANTITY INDICATOR - TRANSMITTER (Ref. AMM TASK 29-11-41-000-002) and (Ref. AMM TASK 29-11-41-400-002).
(2) If the quantity shown is less than 3.5 l (0.9245 USgal):
(a) 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).
(b) Make sure that the drain valve of the hydraulic reservoir has no leaks.
1 If the drain valve has a leak:
_
- replace the drain valve.
2 If the drain valve has no leaks:
_
- do a check of the hydraulic lines and the components for leaks (Ref. AMM TASK 29-00-00-790-001) and repair them.
3 If the fault continues:
_
- do a check of the internal leakage of the Green hydraulic system (Ref. AMM TASK 29-00-00-280-001).
a If the internal leakage rate is too high:
_
- repair the defective component.
b If the fault continues, or you can not find a defective
_
component:
- remove a fuel sample from each water drain-valve (Ref. AMM TASK 12-32-28-281-001),
- do a check for contamination of the fuel with hydraulic fluid after each removal of a fuel sample.
c If you find hydraulic fluid contamination in one or more
_
fuel samples:
- do a check of the hydraulic lines and components in the applicable tank area for leaks and repair them.

B. If the Fault Confirmation gives:
- the message HYD G RSVR LO LVL on the upper ECAM DU,
- the contents indication (shows low fluid level) on the lower ECAM DU in amber:
- Do a visual check of the quantity shown on the mechanical indicator of the Green reservoir.
(1) If the quantity shown is more than or equal to 2.6 l (0.6868 USgal):
(a) 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).
(b) Do a check for 26 VAC between: QUANTITY INDICATOR - TRANSMITTER connector A/D and connector A/E (Ref. ASM 29-31/01).
1 If there is no 26 VAC:
_
- do a check of the wiring between: QUANTITY INDICATOR - TRANSMITTER connector A/D and CB (1831GQ) and repair the wiring as necessary (Ref. ASM 29-31/01).
2 If the fault continues:
_
- do a check for a ground signal between: QUANTITY INDICATOR - TRANSMITTER connector A/E and ground (Ref. ASM 29-31/01).
a If there is no ground signal:
_ - repair the wiring between QUANTITY INDICATOR -TRANSMITTER connector A/E and ground (Ref. ASM 29-31/01).
(c) If the fault continues:
- replace the QUANTITY INDICATOR - TRANSMITTER (Ref. AMM TASK 29-11-41-000-002) and (Ref. AMM TASK 29-11-41-400-002).
(d) If the fault continues:
- do the troubleshooting procedure for the loss of the GREEN RSVR QTY input of the SDAC-1 (1WV1) (Ref. TASK 31-54-00-810-833).
1 If the fault continues:
_
- do the troubleshooting procedure for the loss of the GREEN RSVR QTY input of the SDAC-2 (1WV2) (Ref. TASK 31-54-00-810-834).
