(Ref. TASK 71-00-00-710-001). causes the engine pump of the Green (Yellow) hydraulic system to turn. The ECAM lower display unit (DU) shows the pressure in the Green (Yellow) hydraulic system is 3000 psi approximately.
2.
Operate the sidestick and rudder
pedals so that the control
surfaces move continuously.
3.
On the ECAM Lower DU:
-monitor and make a note of the
Green (Yellow) hydraulic fluid

4. On the ENG/APU FIRE panel 1WD of the overhead panel 20VU: On the ENG/APU FIRE panel 1WD of theoverhead panel 20VU:
- lift the guard and push and release the ENG 1 FIRE (ENG 2 FIRE) P/BSW. - the SQUIB lights of the ENG 1FIRE/AGENT 1 and ENG 1 FIRE/AGENT 2(ENG 2 FIRE/AGENT 1 and ENG 2 FIRE/AGENT 2) come on.
- continue to operate the side stick and the rudder pedals On the ECAM lower DU:
NOTE : The noise that you can____ hear comes from the engine driven pump and is normal
- the fire valve symbol of the GREEN (YELLOW) hydraulic system changes from in-line and green-colored to 90 degrees out-of-line and amber-colored,
- the index of the Green (Yellow) hydraulic fluid level moves up,
- the pressure in the Green (Yellow) hydraulic system decreases to less than 700 psi in not more than 60 s from operation of the P/BSW.
The single chime audio warning operates.
On the glareshield panels 130VU and 131VU:
- the MASTER CAUT lights come on.
NOTE : The FAULT light of the GREEN/ENG____ 1 PUMP (YELLOW/ENG 2 PUMP) P/BSW can come on, if the applicable N2 engine value is reached.
5. Stop the operation of the sidestick and rudder pedals.

- push the ENG 1 FIRE (ENG 2 FIRE) P/BSW, - make sure that the P/BSW guard goes back to its initial position. - the SQUIB lights of the ENG 1FIRE/AGENT 1 and ENG 1 FIRE/AGENT 2(ENG 2 FIRE/AGENT 1 and ENG 2FIRE/AGENT 2) go off.
On the ECAM lower DU:
- the fire valve symbol of the GREEN (YELLOW) hydraulic system changes from 90 degrees out-of-line and amber-colored to in-line and
green-colored.
- the pressure in the Green (Yellow) hydraulic system increases,
- the index of the Green (Yellow) hydraulic fluid level goes back to its initial position.
On the glareshield panels 130VU and 131VU:
- the MASTER CAUT lights go off.
NOTE : It is possible that you must____ reset the MASTER CAUT lights, if messages other than ENGINE NO. 1(2) shut down, be displayed on the ECAM.
7. Stop the dry motoring of the left (right) engine (Ref. TASK 71-00-00-710-001).
8. Open the overhead panel 49VU to get access to the pins of the circuit breaker 1703GK (3702GD).
