(Ref. AMM TASK 27-94-34-400-001).
(b) If the resistance is more than 10 Ohms: 1 Replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and
_ (Ref. AMM TASK 27-94-34-400-001). Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).
2 If the fault continues:
_
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
3 If the fault continues:
_ a Do a check of the wiring of the ACS1 SPLY XDCR signal from
_ the SEC1 MON side to the COM side, pins AE/10D and AE/10E to pins AB/8F and AB/8E (Ref. ASM 27-94/07).
- if the wiring is correct, see Para b_
- if the wiring is not correct, repair the above wiring. b Do a check and repair the wiring of the ACS1 SPLY XDCR COM
_ signal from the SEC1 MON side to the second terminal block, pins AB/9E and AB/9F (Ref. ASM 27-94/07).
B. Do the test given in para. 3.

__________________
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 G ELEV POS XDCR 34CE1 SEC2 OR WIRING FROM R Y ELEV POS XDCR 34CE2 SEC2 COM 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).
(2) At the SEC2 receptacle, do a check of the resistance between the pin AA/12F and the pin AA/12G (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).
