(b) At the ECAM Control Panel, set the WHEEL page:
- if a triangle symbol is red, do the fault isolation procedure for the downlock proximity switch identified in the CFDS message
- if a triangle symbol (which was initially red) goes green, the fault has gone.
NOTE : The red triangle symbol is shown in the position of the
____ nose, left, or right L/G leg, applicable to the downlock proximity switch indentified in the CFDS message. The
Aug 01/05R CES
WHEEL page indications do not identify which LGCIU system has the fault.
4. Fault Isolation_______________
A. Procedure
(1) Do an inspection of the applicable MLG or NLG downlock
proximity-switch sensor and target clearances:
- for the MLG downlock proximity sensors (14GA,15GA,16GA,17GA) do the procedure in the AMM (Ref. AMM TASK 32-31-73-200-001)
- for the NLG downlock proximity sensors (18GA,19GA) do the procedure in the AMM (Ref. AMM TASK 32-31-73-200-002).
(2) Do the test in Para. 3.A.(2)(b).
NOTE : The LGCIU BITE test can not identify errors in
____ proximity-switch target position. Differences between downlock (and uplock) proximity switches (which occur for more than 30 seconds) are sensed independently and the data is used to update the Last Leg Report, Ground Scanning and the WHEEL page.

3. Fault Confirmation
__________________
A. Test
(1) Do a BITE test of the LGCIU-1 (5GA1) or LGCIU-2 (5GA2) identified on the Post Flight Report (PFR):
- if the message LGCIU1(2)/VALVES 40GA/41GA is shown, do the fault isolation procedure in Para. 4.A.
- if a different message is shown, do the trouble shooting procedure related to the maintenance message.
4. Fault Isolation
_______________
A. Procedure
(1) Do the fault isolation procedure for the SEL VALVE-L/G (40GA) (Ref. TASK 32-31-00-810-806).
(a) Do the test in Para. 3.A.:
- if the fault continues, do the next step.
(2) Do the fault isolation procedure for the SEL VALVE-L/G DOORS (41GA) (Ref. TASK 32-31-00-810-807).
(a) Do the test in Para. 3.A.
