- do a check of the wiring of K3-1 signal from the ELAC 1 (2CE1) to the first terminal block COM part and MON part (Ref. ASM 27-93/12).
(a) If there is no continuity, repair the wiring.
(b) If there is continuity:
- do a check of the wiring of the DSI-49 signal from the ELAC 1 (2CE1) to the ELAC 1 (2CE1) COM part and MON part (Ref. ASM 27-93/12).
1 If there is no continuity, repair the wiring.
_
2 If there is continuity:
_
- do a check of the wiring of the K3-1B signal from the ELAC 1 (2CE1) to the first terminal block, (Ref. ASM 27-93/12).
a If there is no continuity, repair the wiring.
_
b If there is continuity:
_
- do a check and repair the wiring of the relay (36CE2) to the ELAC 1 (2CE1) and to the THS actuator (9CE), wiring of the fault signal from the ELAC 1 (2CE1) to the first terminal block, (Ref. ASM 27-93/12).
B. Do the tests given in Para. 3.
Loss of the ADR 1 BUS 3 for the ELAC 1
1. Possible Causes
_______________
- ELAC-1 (2CE1)

4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
ELAC1 COM OR BUS3 FROM ADR1
or
ELAC1 MON OR BUS3 FROM ADR1
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the DGI 06 signal from the ELAC 1 (2CE1) to the first terminal block, COM or MON part as shown in the maintenance message (Ref. ASM 27-92/50).
