3. Fault Confirmation
__________________
A. Test
(1) Do an operational test of the wing-tip brake and the pressure-off brake (Ref. AMM TASK 27-51-00-710-001):
- if the test does not complete in less than 2 minutes do the fault isolation procedure in Para. 4.
- if the test is OK, no more maintenance work is necessary.
4. Fault Isolation
_______________
A. Procedure
(1) Abort the test as follows:
(a) Reset the circuit breaker of the channel on test.
(2) Interchange the SFCCs (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).
(a) Do the test in Para. 3. A.
- if the test is OK, do step (3)
- if the test does not complete, do step (4).

(3) Replace the unserviceable SFCC-1 (21CV) or SFCC-2 (22CV) that was the source of the initial fault.
(a) Do the test in Para. 3. A.
- if the test does not complete, do the next step.
(4) Replace the POWER CONTROL UNIT (6201CM) (Ref. AMM TASK 27-54-51-000-001) and (Ref. AMM TASK 27-54-51-400-001).
(a) Do the test in Para. 3. A:
- if the test does not complete, do the next step.
(5) Do a check of the aircraft wiring between the applicable SFCC and the PCU:
- do the repair.
(a) Do the test in Para. 3. A.

Explanation: Where the * = FLAP 1 or 2 (dependent on the selection) Where the ZZZZ is = SLAT or FLAP Where the XX------XX is = FLAP RELIEF ENABLED.
or = FLAP RELIEF DISABLED. or = FLAP RELIEF CODING FAIL.
Where the YY------YY is = MAX FLAP 35 DEG (CMF).
or = MAX FLAP 40 DEG (IAE).
or = MAX FLAP CODING FAIL.
Where the . is function set (1) or function reset (0).
Where the % is a logic 1 or a logic 0 as given by the input circuit.
