(3) If the refuel system operates correctly with manual control:
- set the MCDU to:
(a) The SYSTEM REPORT/TEST (FUEL).
(b) The FQIS STATUS page.
(4) Replace any LRUs listed on the FQIS STATUS page. Refer to the list of faults in P. Block 101 (ATA 28-42) for the appliceable task number.
(5) Do the pressure refuel with auto control.
(6) If the fault continues:
(a) Set the MCDU to INPUT PARAMETERS page 3, (the bit position -state cross-reference).
(b) Examine the bit positions in the Table that follows:

NOTE : If an above signal is not correct, (a 1 not shown), Refer
____ to the Para. shown in the end column.
NOTE : The preselector(s) INC/DEC switch input to the FQIC will
____ only show a 1 while the INC/DEC switch is held in that position. Not at the central/rest position.
(7) For the automatic refuel mode to be active check the conditions that follow in conjunction with the Table above:
(a) The ground/flight discrete input is set to ground.
(b) The refuel selected discrete is active. The logic for this, incorporated in the aircraft wiring, is condition 1_ or 2_ below:
1 Refuel panel door open and the MODE SELECT switch on the
_ external refuel panel set to REFUEL.
2 The cockpit refuel panel power switch set to on, and the
_ cockpit refuel panel CTL (Control) switch set to on.
(c) All the REFUEL VALVE switches are set to NORMAL.
(8) For an automatic refuel to start make that the conditions are as follows:
(a) Refuel bus power has been present for more than 7 seconds.
(b) Automatic refuel mode is active (see Para. 7).
(c) The displayed preselector FQ is 100kg (200lb) greater than the actual fuel quantity.
