R (1) Make sure that the Post Flight Report does not show any hydraulic R system faults. R
(2) Move the flaps (Ref. AMM TASK 27-50-00-866-008) (Ref. AMM TASK 27-50-00-866-009).
R (a) Examine the SFCC, FLP ON GROUND FAULTS page for a valveblock R message. R
R (b) If a valveblock message is shown, or the A/C has had this fault R before, do the fault isolation procedure.
4. Fault Isolation
_______________
R A. Procedure
R (1) Interchange the SFCC1 and SFCC2 (Ref. AMM TASK 27-51-34-000-001) and R (Ref. AMM TASK 27-51-34-400-001).
R (2) Move the flaps, Ref. Para. 3.A. (2).

R (3) If the fault moves to the other system, replace the applicable SFCC-1
R (21CV) or SFCC-2 (22CV), (Ref. AMM TASK 27-51-34-000-001) and (Ref.
R AMM TASK 27-51-34-400-001).
R (4) If the fault does not move:
R - and the fault message includes the FIN 23CV or 24CV go to Para. (7)
R - and the fault message does not include the FIN 23CV or 24CV
R continue this procedure.
R (5) Do a check of the circuit resistance and circuit isolation of the
R extend and retract solenoid valves as follows:
R CAUTION: DO NOT SHORT CIRCUIT THE WIRING TO THE SOLENOID VALVES.
R DAMAGE TO THE SFCC CAN OCCUR.
R NOTE : A test is not available for the LVDT.____
R (a) Get access to the electrical connector at the applicable VALVE
R BLOCK-FLAP 1 (23CV) or VALVE BLOCK-FLAP 2 (24CV), (Ref. AMM TASK
27-54-53-000-001).
R (b) Use a Multimeter and at the connector do a check and make a note
R of the resistance values between:
R - for SFCC1/VALVE BLOCK-FLAP 1 (23CV), (EXTEND) pins T and U,
R (RETRACT) pins J and H (Ref. ASM 27-51/02)
R - For SFCC2/VALVE BLOCK-FLAP 2 (24CV), (EXTEND) pins T and U,
R (RETRACT) pins J and H (Ref. ASM 27-51/03).
R (c) The resistance values must be as follows:
R - for solenoid valves with Part No. 667C0000-02, between 71 Ohms
R and 84 Ohms.
R - for solenoid valves with Part No. 903A0000-01, between 53 Ohms
R and 60 Ohms.
R - for solenoid valves with Part No. 1106A0000-01 or 1111A0000-01,
R between 53 Ohms and 60 Ohms.
R (d) At the valveblock electrical connector, do a check for circuit
R isolation:
R 1_ For the EXTEND solenoid connect the pins U and T together.
R 2_ For the RETRACT solenoid connect the pins J and H together.
