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).
(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:
L G AIL SERVO VLV 33CE1
- replace the servovalve of the servo control 33CE1, (Ref. AMM TASK 27-14-51-000-003) and (Ref. AMM TASK 27-14-51-400-003).
NOTE : The resistance must be 500 ohms +/- 10 %.

(1) If the fault continues:
- do a check of the wiring POS XDCR signal from the servocontrol (33CE1) to the ELAC 2 (2CE2) COM and MON side, (Ref. ASM 27-93/03).
(2) If the fault continues:
- replace the ELAC-2 (2CE2), (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(3) If the fault continues:
- replace the SERVO CTL-L AILERON, INBD G (33CE1), (Ref. AMM TASK 27-14-51-000-001) and (Ref. AMM TASK 27-14-51-400-001).
B. Do the test given in Para. 3.

CES Failure of the Left Green Aileron Servo Control Solenoid Valve
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 AILERON, INBD G (33CE1)
- ELAC-2 (2CE2)
- solenoid valve of the servo control (33CE1)
- wiring of the SOL VLV signal from the servo control (33CE1) to the ELAC2 (2CE2)
