__________________
 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 ELEV SERVO VLV 34CE1

 - replace the servovalve of the servocontrol 34CE1 (Ref. AMM TASK 27-34-51-000-008) and (Ref. AMM TASK 27-34-51-400-003).
 NOTE : The resistance must be 500 ohms +/- 10 %.
____

 (1) If the fault continues:
 - do a check and repair the wiring of the SV signal from the servocontrol (34CE1) to the first terminal block (Ref. ASM 27-93/08).
 B. Do the test given in Para. 3.

 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 1 and FLT CTL/ELAC 2 pushbutton switches (on these pushbutton switches the OFF legends come 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 test gives the maintenance message: SEC2 COM OR WIRING TO L G ELEV SERVO VLV 34CE1
 - replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
 (1) If the fault continues:
 (a) Do a check of the wiring of the L ELEV SV (ANO 1) signal from the SEC 2 (1CE2) COM part to the MON part, from pins AA/1A, 1B to pins AD/1J, 1K (Ref. ASM 27-94/08):

 - if there is continuity, see Para. (b)

 - if there is no continuity, repair the above wiring.

 (b) Repair the wiring from the SEC 2 (1CE2) MON part, pins AD/1F, 1G to the first terminal block (Ref. ASM 27-94/08).

 B. Do the tests given in Para. 3.
