3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the side stick assembly (activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
NOTE : Before you start the operational test procedure, release the
____ FLT CTL/ELAC 2 pushbutton switch (on this pushbutton switch the OFF legend comes on).
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the tests give the maintenance message ELAC1 OR WIRING TO R Y ELEV SOL VLV 34CE2:
(1) Remove the ELAC1 (Ref. AMM TASK 27-93-34-000-001).
(2) At the ELAC1 receptacle, do a check of the resistance between the pin AB/14K and the pin AE/14B (Ref. ASM 27-93/07).
NOTE : The resistance must be between 40 and 100 Ohms.
____
(a) If the resistance is less than 40 Ohms:
- at the inboard elevator servocontrol (34CE2), do a check of the resistance of the solenoid valve between the pin C/K and the pin C/L (Ref. ASM 27-93/07).
NOTE : The resistance must be between 40 and 100 Ohms.
____
1 If the resistance values are out of the specified limits:
_ a Replace the solenoid valve of the servocontrol 34CE2 (Ref.
_ AMM TASK 27-34-51-000-005) and (Ref. AMM TASK 27-34-51-400-004).
b Do again a check of the resistance of the solenoid valve
_ between the pin C/K and the pin C/L of the inboard elevator servocontrol (34CE2) (40 to 100 Ohms).
- If the resistance values are out of the specified limits: . Replace the SERVO CTL-R ELEVATOR, INBD Y (34CE2) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001). . Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
- If the resistance values are in the specified limits: Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).

2 If the resistance values are in the specified limits:
_
a Repair the wiring of the SOL VLV1 signal from the
_ servocontrol (34CE2) to the ELAC1 (2CE1), from the pin C/K to the pin AB/14K and from the pin C/L to the pin AE/14B (Ref. ASM 27-93/07):
b Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001)
_ and (Ref. AMM TASK 27-93-34-400-001).
(b) If the resistance is more than 100 Ohms:
- at the inboard elevator servocontrol (34CE2), do a check of the resistance of the solenoid valve between the pin C/K and the pin C/L (Ref. ASM 27-93/07).
