3. Fault Confirmation
__________________
A. Not applicable, the fault is evident.
NOTE : You can get more data from the:
____
- Aircraft Maintenance Manual (AMM) Chapters 26-12-00, 26-21-00, 28-24-00, and 76-12-00 - Description and Operation (D and O)
- Trouble Shooting Manual (TSM), Task Supporting Data, (Ref. P. Block 301)
- Aircraft Schematic Manual (ASM) (Ref. ASM 26-21/02), (Ref. ASM 28-24/01), and (Ref. ASM 76-12/01).
4. Fault Isolation
_______________
A. On the ENG/APU FIRE PANEL (1WD) located on the overhead panel 20VU, make sure that the ENG 1 FIRE PUSH pushbutton switch (P/BSW) is in the closed and guarded position.
(1) On the ECAM Control Panel 11VU, push (in) the FUEL P/BSW to get the FUEL system page on the ECAM lower display unit (DU).
(2) Set the ENG/MASTER 1 (3KC) switch (panel 115VU) to OFF.
(3) Disconnect the electrical supply cable connector (9QG-A) from the ACTUATOR-LP FUEL VALVE, ENG 1 (9QG).
(4) Examine the ENG 1 LP fuel valve symbol on the FUEL system page.
(a) If the ENG 1 LP fuel valve symbol shows in transit (diagonal amber line):
1_ Temporarily put a ground/earth on free connector 9QG-A, pin B
and examine the ENG 1 LP fuel valve symbol on the FUEL system
page, - make note.
2_ Remove the ground/earth temporarily placed on free connector
9QG-A, pin B.
3_ Temporarily put a ground/earth on free connector 9QG-A, pin D
and examine the ENG 1 LP fuel valve symbol on the FUEL system
page, - make note.
4_ Remove the ground/earth temporarily placed on free connector
9QG-A, pin D.
5_ If in steps 1_ and 3_ the LP fuel valve symbol agrees with the
table that follows:

--------------------------------------------------------------
- do a check (Ref. AWM 28-24-01) of the aircraft wiring (motor 1/ground/earth) between the ACTUATOR-LP VALVE, ENG 1 (9QG) connector 9QG-A, pin E and the ground/earth point 4001VN(521STA332).
6 Repair all the unserviceable wiring and connectors.
_
7 Connect the electrical supply cable connector 9QG-A to the
_ ACTUATOR-LP VALVE FUEL VALVE, ENG 1 (9QG).
8 Do the Operational Test of the ENG 1(2) LP Fuel Valve
_ 12QM(13QM) (Ref. AMM TASK 28-24-00-710-002).
