4. Fault Isolation
_______________
A. If the tests give the maintenance message R B ELEV MODE VLV 34CE4:
(1) Remove the RELAY-THS MOT 3 INHIBITION 1 (51CE) and RELAY-THS MOT 3 INHIBITION 2 (52CE) (Ref. IPC 27920803).
(2) Do a check of the resistance and insulation of the relays.
NOTE : The resistance of the winding (pins X1 and X2) must be betwwen
____ 280 and 400 ohms; the insulation must be more than 500 KiloOhms.
(a) If the resistance and the insulation are in the specified limits:
- replace the RELAY-THS MOT 3 INHIBITION 1 (51CE) and/or RELAY-THS MOT 3 INHIBITION 2 (52CE) (Ref. IPC 27920803).
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001), (Ref. AMM TASK 27-93-34-400-001).
(b) If the resistance is more than the specified limits:
- replace the RELAY-THS MOT 3 INHIBITION 1 (51CE) and/or RELAY-THS MOT 3 INHIBITION 2 (52CE).
(c) If the resistance and the insulation are between the specified limits:
- install the RELAY-THS MOT 3 INHIBITION 1 (51CE) and RELAY-THS MOT 3 INHIBITION 2 (52CE)
- see Para (3).
(3) If the fault continues:
(4) Remove the ELAC2 (Ref. AMM TASK 27-93-34-000-001).
(5) At the ELAC2 receptacle, do a check of the resistance between the pin AB/14K and the pin AE/14B (Ref. ASM 27-93/08).
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/K and the pin C/L (Ref. ASM 27-93/08).
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 the pin C/K and the pin C/L 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 ELAC-2 (2CE2) (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-2 (2CE2) (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 (34CE4) to the ELAC2 (2CE2), from the pin C/K to the pin AB/14K and from the pin C/L to the pin AE/14B (Ref. ASM 27-93/08):
b Replace the ELAC-2 (2CE2) (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 outboard elevator servocontrol (34CE4), do a check of the resistance of the solenoid valve between the pin C/K and the pin C/L (Ref. ASM 27-93/08).
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 the pin C/K and the pin C/L 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). . Install the ELAC2 (Ref. AMM TASK 27-93-34-400-001).
