(2) At the ELAC1 receptacle, do a check of the resistance between the pin AB/7K and the pin AB/8K (Ref. ASM 27-93/07):
(a) If the resistance is less than 10 Ohms:
1 Do this procedure (Ref. TASK 27-90-00-810-801).
_
2 Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and
_ (Ref. AMM TASK 27-93-34-400-001).
3 Replace the SEC-1 (1CE1) (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 signal from the ELAC1 MON side to the COM side (Ref. ASM 27-93/07): . pins AE/1J and AE/1K to pins AE/10B and AE/11B of ELAC1 MON side . pins AE/10A and AE/11A of the ELAC1 MON side to pins AB/7J and AB/8J of the ELAC1 COM side.
1 If the wiring is not correct:
_
- repair it

b Install the SEC1 (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 ELAC1 COM side to the first terminal block, pins AB/7K and AB/8K (Ref. ASM 27-93/07).
