CAUTION : DO NOT SWAP FLIGHT CONTROL COMPUTERS. IF THERE IS A SHORT CIRCUIT,
_______ YOU WILL CAUSE DAMAGE TO A SERVICEABLE COMPUTER WHEN YOU SWAP THEM.
1. Possible Causes
_______________
- SERVO CTL-R ELEVATOR, OUTBD B (34CE4)
- SEC-2 (1CE2)
- solenoid valve of the servocontrol 34CE4
- wiring of the SOL VLV2 signal from the servocontrol (34CE4) to the SEC2 (1CE2)
- wiring from the SEC2 (1CE2) COM part to the SEC2 MON part

__________________
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 1 and FLT CTL/ELAC 2 pushbutton switches (on these pushbutton switches the OFF legends come 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 test gives the maintenance message:
SEC2 MON OR WIRING TO R B ELEV SOL VLV 34CE4
(1) Remove the SEC2 (Ref. AMM TASK 27-94-34-000-001).
(2) At the SEC2 receptacle, do a check of the resistance between the pin AB/15D and the pin AE/15G (Ref. ASM 27-94/08).
NOTE : The resistance must be between 40 and 100 Ohms.
____
(a) If the resistance is less than 40 Ohms:
- at the outboard elevator servocontrol (34CE4), do a check of the resistance of the solenoid valve between the pin C/J and the pin C/U (Ref. ASM 27-94/08).
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 34CE4 (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 pin C/J and the pin C/U of the outboard elevator servocontrol (34CE4) (40 to 100 Ohms).
- If the resistance values are out of the specified limits: . Replace the SERVO CTL-R ELEVATOR, OUTBD B (34CE4) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001). . Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
- If the resistance values are in the specified limits: Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
2 If the resistance values are in the specified limits:
_ a Repair the wiring of the SOL VLV2 signal from the
_ servocontrol (34CE4) to the SEC2 (1CE2), from the pin C/J to the pin AB/15D and from the pin C/U to the pin AE/15G (Ref. ASM 27-94/08):
b Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001)
_ and (Ref. AMM TASK 27-94-34-400-001).
(b) If the resistance is more than 100 Ohms:
- at the outboard elevator servocontrol (34CE4), do a check of the resistance of the solenoid valve between the pin C/J and the pin C/U (Ref. ASM 27-94/08).
