3. Fault Confirmation
__________________
A. For the fault confirmation do the fault isolation.
4. Fault Isolation
_______________
A. Procedure
(1) Do the reset of the WTB's (Ref. AMM TASK 27-80-00-869-004).
(a) Do the operational test of the wing tip brake and the pressure-off brake (Ref. AMM TASK 27-81-00-710-001) to find the unserviceable system, then do the next step. CAUTION: DO NOT SHORT CIRCUIT THE WIRING TO THE SOLENOID VALVES.
DAMAGE TO THE SFCC CAN OCCUR
(2) Get access to the electrical connector on each valve block (Ref. AMM TASK 27-84-53-000-001):
(a) At the connector receptacle, use a Multimeter to measure the resistance between pins K and L for each POB solenoid (Ref. ASM 27-81/03), which must be as follows:
- for solenoid valves with Part No. 667C0000-02, between 71 Ohms and 84 Ohms
- for solenoid valves with Part No. 903A0000-01, between 53 Ohms and 60 Ohms
- for solenoid valves with Part No. 1106A0000-01 or 1111A0000-01, between 53 Ohms and 60 Ohms.
(b) If the resistance value:
- is not correct, replace the unserviceable POB Solenoid, (Ref. AMM TASK 27-84-53-000-002) and (Ref. AMM TASK 27-84-53-400-002)
- is correct, do the next step.
(3) Interchange SFCC-1 and SFCC-2 (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).
(a) Do the test given in step (1)
- if the fault moves to the opposite system, replace the SFCC-1 (21CV) or SFCC-2 (22CV) in the unserviceable system (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001)
- if the fault stays in the same system, replace the Pressure-off Brake,, (Ref. AMM TASK 27-84-52-000-001) and (Ref. AMM TASK 27-84-52-400-001).

(4) If the fault continues, replace the applicable POB Solenoid, (Ref. AMM TASK 27-84-53-000-002) and (Ref. AMM TASK 27-84-53-400-002).
5. Close-up
________
A. Remove the ground support and maintenance equipment, the special and standard tools and all other items.
B. Put the aircraft back to its initial configuration.
