(5) Replace the applicable proximity-sensor (Ref. AMM TASK 52-71-12-000-001) and (Ref. AMM TASK 52-71-12-400-001):
- if the fault continues, do step (6).
(6) Replace the applicable LGCIU:
- if the PFR shows a message related to proximity-switches 28W, 30W, 32W or 34W, replace the LGCIU-1 (5GA1), (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001)
- if the PFR shows a message related to proximity-switches 05MJ or 12MJ, replace the LGCIU-2 (5GA2) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(a) Do the test in Para 3.A.
NOTE : To identify a TGT POS fault, the LGCIU has to be correctly
____ connected to the related proximity sensor. Thus a check of the aircraft wiring is not necessary.

A. Test
(1) You cannot create the fault condition on the ground. NOTE : The fault messages shown on the Post Flight Report occur
____ because the NLG door/s move away from the locked down position before the NLG completes the retraction cycle.
4. Fault Isolation
_______________
A. Procedure
(1) Do the task (Ref. TASK 32-31-00-810-854) and make sure that these proximity sensors PROX SNSR-NLG R DOOR OPEN, SYS 1 (36GA), PROX SNSR-NLG L DOOR OPEN, SYS 1 (37GA), PROX SNSR-NLG R DOOR OPEN, SYS 2 (38GA) and PROX SNSR-NLG L DOOR OPEN, SYS 2 (39GA) and the clearance with their related targets are OK.
