- push the FLT CTL/ELAC 1 pushbutton switch (on this pushbutton switch, the OFF legend goes off).
4. Fault Isolation
_______________
A. If the test gives the maintenance message: L B AIL MODE VLV 33CE3
(1) Remove the ELAC1 (Ref. AMM TASK 27-93-34-000-001).
(2) At the ELAC1 receptacle, do a check of the resistance between pin AA/7G and pin AD/10C (Ref. ASM 27-93/02).
NOTE : The resistance must be between 40 and 100 Ohms.
____
(a) If the resistance is less than 40 Ohms:
- at the outboard aileron servocontrol (33CE3), do a check of the resistance of the solenoid valve between pin A/H and pin A/T (Ref. ASM 27-93/02).
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 (33CE3),
_ (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
R between pin A/H and pin A/T of the outboard aileron
R servocontrol (33CE3) (40 to 100 Ohms).
- If the resistance values are out of the specified limits:
. Replace the SERVO CTL-L AILERON, OUTBD B (33CE3) (Ref.
AMM TASK 27-14-51-000-001) and (Ref. AMM TASK 27-14-51-
400-001).

b Do again a check of the resistance of the solenoid valve
_ R between pin A/H and pin A/T of the outboard aileron R servocontrol (33CE3) (40 to 100 Ohms).
- If the resistance values are out of the specified limits: . Replace the SERVO CTL-L AILERON, OUTBD B (33CE3) (Ref. AMM TASK 27-14-51-000-001) and (Ref. AMM TASK 27-14-51-400-001). . Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).
- If the resistance values are in the specified limits: Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).
2 If the resistance values are in the specified limits:
_
R a_ Repair the wiring of the SOL VLV signal from the servoR control (33CE3) to the ELAC1 (2CE1) (Ref. ASM 27-93/02).
