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 ELEV pos XDCR 34CE1 COM E2/S2:USE STBY XDCR
- refer to Para. Fault Isolation.

(b) If the ground scanning gives at least two maintenance messages of the list below: L G ELEV pos XDCR 34CE1 COM E2/S2:USE STBY XDCR R Y ELEV pos XDCR 34CE2 COM E2/S2:USE STBY XDCR ELAC2 COM OR INPUT OF THS ACTR XDCR1 9CE SEC2 COM OR INPUT OF THS ACTR XDCR3 9CE
- do this trouble shooting procedure (Ref. TASK 27-90-00-810-823).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
L G ELEV POS XDCR 34CE1 COM E2/S2 : USE STBY XDCR
- deactivate the defective RVDT and connect the spare RVDT (Ref. AMM TASK 27-34-00-040-001) and (Ref. AMM TASK 27-34-00-440-001).
(1) If the fault continues:
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-933) related to the ANI 2-X analog input signal of the ELAC COM and SEC COM (Ref. ASM 27-93/07) and (Ref. ASM 27-94/07).
(2) If the fault continues:
- replace the SERVO CTL-L ELEVATOR, INBD G (34CE1) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).
NOTE : The resistance of primary and secondary windings must be
____
between 30 ohms and 500 ohms.
(3) If the fault continues:
(a) Do a check of the wiring of the POS XDCR COM SPLY signal from the servocontrol (34CE1) to the first terminal block (Ref. ASM 27-93/08):
- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.
(b) Do a check and repair the wiring of the POS XDCR COM V1, V2 signals from the servocontrol (34CE1) to the first terminal block (Ref. ASM 27-93/08).
B. Do the tests given in Para. 3.
