(2) If the test gives the message LGCIUx(5GAx)/VHFy(1RCy), do the procedure in Para. 4. A.
NOTE : x = 1 with y = 1, x = 2 with y = 2, x = 2 with y = 3.

4. Fault Isolation
_______________
A. Procedure
(1) Do a BITE test of the applicable LGCIU (Ref. AMM TASK 32-69-00-740-001).
(2) If the test gives a fault message that includes the LGCIU, replace the applicable LGCIU-1 (5GA1) or LGCIU-2 (5GA2), (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(3) If the test gives the message TEST OK:
- do a check of the aircraft wiring between the applicable transceiver and the applicable LGCIU, (Ref. ASM 23-12/00), (Ref. ASM 23-12/00) or (Ref. ASM 23-12/00)
- repair all the unserviceable wiring and connectors
- do the test in Para. 3.A.
(4) If the fault continues:
- replace the applicable XCVR-VHF, 1 (1RC1), XCVR-VHF, 2 (1RC2) or XCVR-VHF, 3 (1RC3), (Ref. AMM TASK 23-12-33-000-001) and (Ref. AMM TASK 23-12-33-400-001).

A. Test
Functional Test of the Normal Extension and
Retraction of the Landing Gear
Removal of the Landing Gear Normal Control lever
(6GA)
Installation of the Landing Gear Normal Control Lever
(6GA)
Removal of the LGCIU (5GA1, 5GA2)
Installation of the LGCIU (5GA1, 5GA2)
(1) If the L/G lever does not move to the UP position during a L/G retraction, do the Functional Test of the Normal Retraction and Extension of the Landing Gear (Ref. AMM TASK 32-31-00-720-002):
- if the control lever does not move, because the retraction inhibit baulk solenoid does not release correctly, do the fault isolation procedure in Para. 4.A. (1)
- if the control lever moves correctly, when LGCIU 1 only is in control, do the fault isolation procedure in Para. 4.A.(7)
- if the control lever moves correctly, when LGCIU 1 only is in control and also when LGCIU 2 only is in control, then no more maintenance work is necessary.
NOTE : System 1 and System 2 each operate the baulk solenoid circuit
____ independently. Thus for the baulk solenoid circuit not to operate there must be two faults, one in each system. Thus it is necessary to isolate System 2 and trouble shoot System 1, then isolate System 1 and trouble shoot System 2.

A. Procedure
(1) If the Post Flight Report (PFR) shows a shock-absorber proximity-sensor maintenance message, do the trouble shooting procedure related to the maintenance message.
