B. Test
(1) Energize the aircraft electrical circuits AMM 24-41-00-861-002.
(2) Make sure that the fuel C/Bs that follow are closed:
(4) Open the REFUEL panel door 192MB/522KB/622KB or (if installed) set the cockpit refuel PWR P/BSW (23QU) to on.
(5) Monitor the upper ECAM Display Unit (DU), left memo section of the display, for the refueling message REFUELG.
(6) If the memo REFUELG:
(a) Is shown, maintenance steps are not necessary.
(b) Is not shown, go to Para. 4.A.
4. Fault Isolation(1) Energize the aircraft electrical circuits AMM 24-41-00-861-002.
(2) Make sure that the fuel C/Bs that follow are closed:
- 1QJ
- 1QT
- 2QT
- 8QT
- 2QU.
(4) Open the REFUEL panel door 192MB/522KB/622KB or (if installed) set the cockpit refuel PWR P/BSW (23QU) to on.
(5) Monitor the upper ECAM Display Unit (DU), left memo section of the display, for the refueling message REFUELG.

Subtask 28-25-00-810-058-A ** ON A/C NOT FOR ALL
A. Procedure
(1) Make sure that the REFUEL panel door is open.
(2) At the CTL PNL-REFUEL/DEFUEL (800VU), do the steps that follow to check the availability of the different 28VDC refueling supplies:
(a) 28VDC Refueling Bus 1 501PP
1 C/B-1QJ output
Do the HI LVL LTS TEST AMM 12-11-28-650-003 to see if they come on/illuminate.
2 C/B-2QU output
Monitor the FLOODLIGHT-REFUEL/DEFUEL CTL PNL (32QU) to see if it is on/illuminated.
(b) 28VDC Refueling Bus 2 502PP
1 C/B-8QT
Monitor the displays of the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT) and the IND-FUEL QTY MULTI TANK (6QT) to see if they come on/are energized.
(3) If all three of the checks in step (2) operate or illuminate correctly, go to step (6).
(4) If one of the checks in step (2) does not operate or illuminate correctly, go and do the applicable troubleshooting.
(5) If all three of the checks in step (2) do not operate or illuminate correctly, do Refueling not Possible (Ref. TSM TASK 24-67-00-810-801).
(6) Temporarily replace the FQIC [3QT] AMM 28-42-34-000-001 and AMM 28-42-34-400-001.
(7) If the REFUELG memo message is shown:
Subtask 28-25-00-810-058-B ** ON A/C NOT FOR ALL (1) Make sure that the REFUEL panel door is open.
(2) At the CTL PNL-REFUEL/DEFUEL (800VU), do the steps that follow to check the availability of the different 28VDC refueling supplies:
(a) 28VDC Refueling Bus 1 501PP
1 C/B-1QJ output
Do the HI LVL LTS TEST AMM 12-11-28-650-003 to see if they come on/illuminate.
2 C/B-2QU output
Monitor the FLOODLIGHT-REFUEL/DEFUEL CTL PNL (32QU) to see if it is on/illuminated.
(b) 28VDC Refueling Bus 2 502PP
1 C/B-8QT
Monitor the displays of the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT) and the IND-FUEL QTY MULTI TANK (6QT) to see if they come on/are energized.
(3) If all three of the checks in step (2) operate or illuminate correctly, go to step (6).
(4) If one of the checks in step (2) does not operate or illuminate correctly, go and do the applicable troubleshooting.
(5) If all three of the checks in step (2) do not operate or illuminate correctly, do Refueling not Possible (Ref. TSM TASK 24-67-00-810-801).
(6) Temporarily replace the FQIC [3QT] AMM 28-42-34-000-001 and AMM 28-42-34-400-001.
(7) If the REFUELG memo message is shown:
- complete the installation of the FQIC (3QT) AMM 28-42-34-000-001 and AMM 28-42-34-400-001.
- install the initial FQIC (3QT) AMM 28-42-34-000-001 and AMM 28-42-34-400-001
- the C/B-FUEL/FQI/CHANNEL/1 AND 2 (8QT) and the FQIC rack connector AB, pin 9D (refuel bus powered input supply wire to the FQIC).
NOTE: This is the 28VDC (discrete) input that causes the ARINC label 276, bit 21 to be set to a 1.
