__________________
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, FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton

Aug 01/03 CES 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:
SEC1 MON OR WIRING TO L B ELEV SERVO VLV 34CE3
- replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
(a) replace the XDCR UNIT-ELEV POS, L (49CE1) (Ref. AMM TASK 27-92-13-000-001) and (Ref. AMM TASK 27-92-13-400-001).
(2) If the fault continues:
- replace the servovalve of the servocontrol 34CE3 (Ref. AMM TASK 27-34-51-000-008) and (Ref. AMM TASK 27-34-51-400-003).
(3) If the fault continues:
(a) Replace the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).
(4) If the fault continues:
(a) Do a check of the wiring of SV XDCR V1 signal from the servocontrol (34CE3) to the SEC 1 (1CE1) (Ref. ASM 27-94/07):
- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.
(b) Do a check of the wiring of the SV XDCR SPLY signal from the servocontrol (34CE3) to the first terminal block (Ref. ASM 27-94/07):
- if there is continuity, see Para. (c)
- if there is no continuity, repair the above wiring.
R (c) Check and repair the wiring of the POS XDCR MON signal from the R transducer unit (49CE1) to the SEC 1 (1CE1) (Ref. ASM 27-94/07):
B. Do the tests given in Para. 3.
