(1) If the fault continues:
- do a check of the wiring POS XDCR signal from the servocontrol (33CE4) 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-R AILERON, OUTBD B (33CE4), (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 Right Blue 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-R AILERON, OUTBD B (33CE4)
- ELAC-2 (2CE2)
- solenoid valve of the servo control (33CE4)
- wiring of the SOL VLV signal from the servo control (33CE4) to the ELAC2 (2CE2)

B. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
NOTE : Before you push the line key adjacent to the START GROUND SCAN
____ indication, release the FLT CTL/ELAC 2 pushbutton switch on the overhead panel 24VU (on this pushbutton switch the OFF legend comes on) and wait for 30 s.
C. Put the aircraft back to its initial configuration.
(1) Depressurize the aircraft hydraulic systems (Ref. AMM TASK 29-10-00-864-003), (Ref. AMM TASK 29-23-00-864-001), (Ref. AMM TASK 29-24-00-864-001).
(2) On the overhead panel 24VU:
- push the FLT CTL/ELAC 2 pushbutton switch (on this pushbutton switch, the OFF legend goes off).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
R B AIL MODE VLV 33CE4
(1) Remove the ELAC2 (Ref. AMM TASK 27-93-34-000-001).
(2) At the ELAC2 receptacle, do a check of the resistance between pin AA/7J and pin AD/10A (Ref. ASM 27-93/03).
NOTE : The resistance must be between 40 and 100 Ohms.
____
(a) If the resistance is less than 40 Ohms:
- at the outboard aileron servocontrol (33CE4), do a check of the resistance of the solenoid valve between pin A/H and pin A/T (Ref. ASM 27-93/03).
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 servo control (33CE4),
_ (Ref. AMM TASK 27-14-51-000-004) and (Ref. AMM TASK 27-14-51-400-004).
b Do again a check of the resistance of the solenoid valve
