(7) On the Valveblock, do a check for circuit isolation.
(a) For the POB solenoid connect the pins L & K together.
(b) Connect one test lead of the 45Vdc Isolation Tester to the pins LK and the other test lead to pin G.
(c) Supply a test signal for 5 seconds and read the shown resistance value
(d) the resistance value must be greater than 100Megohms.
(8) If the POB SOLENOID fails one of the two tests at Para 4.A.(2) and
(3) replace the POB solenoid (Ref. AMM TASK 27-54-52-000-001) (Ref. AMM TASK 27-54-52-400-001)
(9) If the tests at Para 4.A(2). and (3) are satisfactory.
(10) Do the operation given in Para 4.A.(1).
(11) Set the MCDU to MENU MODE and access the FLP ON GROUND FAULTS page and make sure that the ground log is clear.
(12) If the CFDS shows the same fault message,then the fault is with the PCU valveblock
(a) Examine the valveblock FILTERS (Ref. AMM TASK 27-54-53-000-003) (Ref. AMM TASK 27-54-53-400-003) and clean/replace the examined item.
(b) Do the test at Para.4.A.(1) and do a check of the FLP ON GROUND FAULTS page, If the fault stays.
(c) Examine the VALVE BLOCK-FLAP 1 (23CV) or VALVE BLOCK-FLAP 2 (24CV) and replace the faulty item. (Ref. AMM TASK 27-54-53-000-001) (Ref. AMM TASK 27-54-53-400-001)
(d) Do the operation at Para.4.A.(1) and make sure the ground log is clear.
(e) Do the SFCC 1 (2) reset, refer to Para.3.B.
