3. Fault Confirmation
__________________
A. Test
(1) This task is for the fault as reported in the "LAST LEG REPORT" by the LGCIU-1 (2) and is valid only if there are "NO" reported CFDIU faults.
(2) On the A/C, set the MCDU to the interactive mode (MENU MODE) and access the L/G SYSTEM REPORT. The fault confirmation is that the SYSTEM REPORT is not available.

Nov 01/00 CES B. LGCIU Reset and Initialization.
(1) At the circuit breakers for LGCIU-1 (2).
(a) Open the circuit breakers.
(b) Close the circuit breakers.
(c) Examine the ECAM for the fault warning.
(d) If the fault warning on the ECAM clears, set the MCDU to MENU MODE and access the L/G SYSTEM REPORT.
(2) If the SYSTEM REPORT is available, dialog is available and the LGCIU-1 (2) is reset and the ECAM fault warning clears.
(3) Do GROUND SCANNING and make sure the fault condition is cleared from the ground log.
(4) If you can not set the SYSTEM REPORT for the LGCIU-1, do the procedure for the CFDIU switching to back-up mode, (Ref. AMM TASK 31-32-00-869-001).
NOTE : This procedure is not available for the LGCIU-2.
____
(5) Do the procedure at Para. 4.B.(1), If dialog is not available, replace the LGCIU-1 (5GA1) (Ref. AMM TASK 32-31-71-000-001) (Ref. AMM TASK 32-31-71-400-001)
(6) Do the procedure at Para 4.B.(1) to reset the LGCIU-1 and to clear the ECAM warning.
(7) If you cannot set the SYSTEM REPORT for LGCIU-2.
(a) Remove ground power.
(b) Swap LGCIU-1 with LGCIU-2.
(c) Do the procedure for CFDIU switching to back-up mode (Ref. AMM TASK 31-32-00-869-001)
(d) Do the Para. 4.B.(1)
(8) If the SYSTEM REPORT is not available, replace the LGCIU-2,
(9) Install the LGCIU-1 in its initial location.
(10) Repeat Para.4.B.(1) to reset the LGCIU-2 and clear the ECAM warning.

Feb 01/98 CES
(11) If the fault still shows, do the CFDIU BITE (Ref. AMM TASK 31-32-00-740-002)
(a) If the CFDIU BITE shows a fault condition, do the CFDIU Trouble Shooting (Refer to TSM 31-32-00)
(b) If the CFDIU shows a "NO" fault condition, do a check of the A/C wiring/interface from the CFDIU ARINC tray to the LGCIU 1 (2) ARINC tray (Ref. ASM 32-31/02)
5. Close-up
________
A. Put the aircraft back to its initial configuration.
