_______________
 - ELAC-2 (2CE2) R - MODE XDCR of the servo control (33CE1)
 - wiring of the MODE XDCR SPLY signal from the servo control (33CE1) to the first terminal block

 - wiring of the MODE XDCR VS1, VS2 signal from the servo control (33CE1) to the ELAC 2 (2CE2)

 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).

 (a) If the ground scanning gives the maintenance message: L G AIL MODE XDCR 33CE1 OR INPUT OF ELAC 2

 - refer to the Para. Fault Isolation.

 (b) If the ground scanning gives the maintenance messages: L G AIL MODE XDCR 33CE1 OR INPUT OF ELAC 2 R B AIL MODE XDCR 33CE4 OR INPUT OF ELAC 2

 - refer to this procedure (Ref. TASK 27-90-00-810-810).

 4. Fault Isolation
_______________

 A. If the test gives the maintenance message: L G AIL MODE XDCR 33CE1 OR INPUT OF ELAC 2 - replace the ELAC-2 (2CE2), (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
R  (1) If the fault continues: - replace the MODE XDCR of the servo control (33CE1), (Ref. AMM TASK 27-14-51-000-005) and (Ref. AMM TASK 27-14-51-400-005). 
R R R R R R R R R R R R R  NOTE : The resistance of primary (pins A/K and A/L) and secondary____ (pins A/J and A/U) windings of the transducer must be between 30 ohms and 500 ohms. The insulation must be more than 100 Mohms. These values are given for information only. You can use these values to do checks of the component electrical part or of the wiring before you replace the component. But by this procedure, the check of the component mechanical part is not done. For primary winding (power supply): - if you do the resistance check from the avionics compartment, you must disconnect the transducer of the Right Blue Aileron Servo Control.
 (2) If the fault continues:
 (a) Do a check of the wiring of the MODE XDCR SPLY signal from the servo control (33CE1) to the first terminal block, (Ref. ASM 27-93/03): - if there is no continuity, repair the wiring - if there is continuity, see Para. (b).
 (b) Do a check and repair the wiring of the MODE XDCR VS1, VS2 signal from the servo control (33CE1) to the ELAC 2 (2CE2), (Ref. ASM 27-93/03).
 B. Do the test given in Para. 3.

 Failure of the Left Green Aileron Servo Control Servovalve
 1. Possible Causes
_______________
 - ELAC-2 (2CE2)

 - SERVO CTL-L AILERON, INBD G (33CE1)

 - servovalve of the servo control 33CE1

 - wiring POS XDCR signal from the servocontrol (33CE1) to the ELAC 2 (2CE2) COM and MON side
