- ELAC-1 (2CE1)
- RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2)
- Electronic Module 2
- wiring of K3-1 signal from the ELAC 1 (2CE1) to the first terminal block
- wiring of the DSI-49 signal from the ELAC 1 (2CE1) to the ELAC 1 (2CE1)
- wiring of the K3-1B signal from the ELAC 1 (2CE1) to the first terminal block
- 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

(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
NOTE : Wait 60 seconds before you start the BITE test.

4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
THS ACTR SERVO MOT2 9CE OF ELAC1
R (1) Remove the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2) (Ref. IPC
R 27920803020).
R (2) Do a check of the resistance between pin X1 and X2 of the relay.
R (a) if the resisance is less than 280 ohms:
R - replace the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2).
R - replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001)
R (Ref. AMM TASK 27-93-34-400-001).
R (b) If the resistance is more than 400 ohms:
R - replace the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2).
R (c) If the resistance is between 280 and 400 ohms:
R - install the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2)
R - see Para (3).
R (3) 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).
R (4) If the fault continues:
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-932) related to the DSI 24 discret input signal of the ELAC 1 and SEC 1 (Ref. ASM 27-93/12) (Ref. ASM 27-93/13) (Ref. ASM 27-94/12) (Ref. ASM 27-94/13) and
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-933) related to the ANI 2-3 analog input signal of the ELAC 1 and SEC 1 (Ref. ASM 27-93/12) and (Ref. ASM 27-94/12).
R (5) If the fault continues:
- replace the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2) Ref. IPC 27920803.
R (6) If the fault continues:
