A. If the ground scanning gives at least two maintenance messages of the list below: L B ELEV POS XDCR 34CE3 COM E1/S1 : USE STBY XDCR R B ELEV POS XDCR 34CE4 COM E1/S1 : USE STBY XDCR THS ACTR XDCR2 9CE
(1) Remove the ELAC1 (Ref. AMM TASK 27-93-34-000-001) and the SEC1 (Ref. AMM TASK 27-94-34-000-001).
(2) At the SEC1 receptacle, do a check of the resistance between the pin AA/12F and the pin AA/12G (Ref. ASM 27-94/07):
(a) If the resistance is less than 10 Ohms:
1 Do this procedure (Ref. TASK 27-90-00-810-801).

_ (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:
_
- do a check and repair the wiring of the ACS1 SPLY XDCR signal from the SEC1 COM side to the second terminal block, pins AA/12F and AA/12G (Ref. ASM 27-94/07).
B. Do the test given in para. 3.
