 - 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

__________________
 A. Test
 (1) Do the operational test of the THS actuator electrical control (Ref. AMM TASK 27-96-00-710-022).
 NOTE : Do the ground setting only with the ELAC 1.

 (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:
