3. Fault Confirmation
__________________
A. Test
(1) Make sure that the Post Flight Report does not show any hydraulic system faults.
(2) Move the slats (Ref. AMM TASK 27-80-00-866-004) and (Ref. AMM TASK 27-80-00-866-005).
R (a) Examine the SFCC, SLT ON GROUND FAULTS page for a PCU valve block R message.
R (3) If a valve block message is shown, or the A/C has had this fault R before, do the fault isolation procedure.
4. Fault Isolation
