3. Fault Confirmation
__________________
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: ELAC2 MON OR INPUT OF THS ACTR XDCR1 9CE ELAC2 OR WIRING FROM L ELEV POS MON XDCR ELAC2 OR WIRING FROM R ELEV POS MON XDCR ELAC2 OR WIRING FROM L B ELEV MODE XDCR 34CE3 ELAC2 OR WIRING FROM R Y ELEV MODE XDCR 34CE4
(1) Remove the ELAC2 (Ref. AMM TASK 27-93-34-000-001) and the SEC2 (Ref. AMM TASK 27-94-34-000-001).

(2) At the ELAC2 receptacle, do a check of the resistance between the pin AB/7K and the pin AB/8K (Ref. ASM 27-93/08):
(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 value is more than 10 Ohms:
- do a check of the wiring of the ACS1 SPLY signal from the ELAC2 MON side to the COM side (Ref. ASM 27-93/08): . pins AE/1J and AE/1K to pins AE/11B and AE/10B of the ELAC2 MON side . pins AE/10A and AE/11A of the ELAC2 MON side to pins AB/8J and AB/7J of the ELAC2 COM side.
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 ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
2 If the wiring is correct:
_ a Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001)
_ and (Ref. AMM TASK 27-93-34-400-001).
b Install the SEC2 (Ref. AMM TASK 27-94-34-400-001).
_
c If the fault continues:
_
- do a check and repair the wiring of the ACS1 SPLY MON signal from the ELAC2 COM side to the first terminal block, pins AB/7K and AB/8K (Ref. ASM 27-93/08).
B. Do the test given in para. 3.
