(b) If the resistance is less than 100 Megohms:
- at the SERVO CTL-L ELEVATOR, INBD G (34CE1), do a check of the insulation of the solenoid valve between pin C/K (pin C/L) and the ground.
1 If the resistance is less than 100 Megohms:
_ Replace the solenoid valve (Ref. AMM TASK 27-34-51-000-005) and (Ref. AMM TASK 27-34-51-400-004).
a Do again a check of the insulation of the solenoid valve
_ between pin C/K (pin C/L) and the ground. If the resistance is less than 100 Megohms: . Replace the SERVO CTL-L ELEVATOR, INBD G (34CE1) (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).
2 If the resistance is more than 100 Megohms:
_
a Repair the wiring of the solenoid valve signal from the
_ SERVO CTL-L ELEVATOR, INBD G (34CE1) to the ELAC-1 (2CE1).
b Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001)
_ and (Ref. AMM TASK 27-93-34-400-001).

CES Loss of the Signal of the Left Green Elevator-Servocontrol Solenoid Valve by the ELAC 1
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-L ELEVATOR, INBD G (34CE1)
- ELAC-1 (2CE1)
- ELAC-2 (2CE2)
- solenoid valve of the servocontrol 34CE1
- wiring of the SOL VLV1 signal from the servocontrol (34CE1) to the ELAC1 (2CE1)
- wiring from the ELAC1 (2CE1) COM part to the ELAC1 COM part
- wiring from the ELAC1 (2CE1) COM part to the ELAC1 MON part
- wiring from the ELAC1 (2CE1) MON part pins AE/13A and AE/10C to the first terminal block

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 L G ELEV SOL VLV 34CE1:
(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/14J and the pin AE/14A (Ref. ASM 27-93/07).
NOTE : The resistance must be between 40 and 100 Ohms.
