__________________
A. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message CHECK PITCH CHANGE OVER OF SEC1:
- replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
(a) Do a check of the wiring of the PITCH NOT AVAIL IN ELAC2 (DSI11 and DSI22) signals from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/32):
- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.

(b) Do a check of the wiring of the PITCH NOT AVAIL IN ELAC1 (DSI10 and DSI26) signals from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/33):
- if there is continuity, see Para. (c)
- if there is no continuity, repair the above wiring.
(c) Do a check of the wiring of the L ELEV NOT AVAIL IN SEC2 (DSI13 and DSI27) signals from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/34):
- if there is continuity, see Para. (d)
- if there is no continuity, repair the above wiring.
(d) Do a check of the wiring of the R ELEV NOT AVAIL IN SEC2 (DSI15 and DSI23) signals from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/34):
- if there is continuity, see Para. (e)
- if there is no continuity, repair the above wiring.
(e) Do a check of the wiring of the L ELEV NOT AVAIL IN SEC1 (DSI05) signal from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/35):
- if there is continuity, see Para. (f)
- if there is no continuity, repair the above wiring.
(f) Do a check and repair the wiring of the R ELEV NOT AVAIL IN SEC1 (DSI06) signal from the SEC1 (1CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/35).
B. Do the test given in Para. 3.
