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 ground scanning gives at least two maintenance messages of the list below: SEC2 OR WIRING FROM L B ELEV MODE XDCR 34CE3 SEC2 OR WIRING FROM L ELEV POS MON XDCR SEC2 OR WIRING FROM R B ELEV MODE XDCR 34CE4 SEC2 OR WIRING FROM R ELEV POS MON XDCR SEC2 MON OR INPUT OF THS ACTR XDCR3 9CE
(1) Remove the ELAC2 (Ref. AMM TASK 27-93-34-000-001) and the SEC2 (Ref. AMM TASK 27-94-34-000-001).

CES
(2) At the SEC2 receptacle, do a check of the resistance between the pin AB/9E and the pin AB/9F (Ref. ASM 27-94/08):
(a) If the resistance is less than 10 Ohms:
1 Do this procedure (Ref. TASK 27-90-00-810-801).
_ 2 Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and
_
(Ref. AMM TASK 27-93-34-400-001).
3 Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and
_
(Ref. AMM TASK 27-94-34-400-001).
(b) If the resistance is more than 10 Ohms:
- do a check of the wiring of the ACS1 SPLY XDCR signal from the SEC2 MON side to the COM side: . pins AE/10E and AE/10D to pins AB/8E and AB/8F (Ref. ASM 27-94/08).
1 If the wiring is not correct:
_
- repair it
- install the ELAC2 (Ref. AMM TASK 27-93-34-400-001) and the SEC2 (Ref. AMM TASK 27-94-34-400-001).
a If the fault continues:
_
- replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
2 If the wiring is correct:
_ a Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001)
_ and (Ref. AMM TASK 27-94-34-400-001).
b Install the ELAC2 (Ref. AMM TASK 27-93-34-400-001).
_
c If the fault continues:
_
- do a check and repair the wiring of the ACS1 SPLY MON signal from the SEC2 COM side to the first terminal block, pins AB/9E and AB/9F (Ref. ASM 27-94/08).
B. Do the test given in para. 3.
