__________________
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 B ELEV POS XDCR 34CE3 COM E1/S1 : USE STBY XDCR
- refer to Para. Fault Isolation.

(b) If the ground scanning gives at least two maintenance messages of the list below: L B ELEV POS XDCR 34CE3 COM E1/S1 : USE STBY XDCR R B ELEV POS XDCR 34CE4 COM E1/S1 : USE STBY XDCR THS ACTR XDCR2 9CE
R - do this trouble shooting procedure (Ref. TASK 27-90-00-810-R 819).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
L B ELEV POS XDCR 34CE3 COM E1/S1 : 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, OUTBD B (34CE3) (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 (34CE3) to the first terminal block (Ref. ASM 27-93/07):
- 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 (34CE3) to the first terminal block (Ref. ASM 27-93/07).
B. Do the tests given in Para. 3.
Loss of the Signal of the Left Blue Elevator-Servocontrol Position-Transducer
by the SEC 1
1. Possible Causes
_______________
- SEC-1 (1CE1)
- wiring of the POS XDCR COM (ANI 2-1) signal from the SEC 1 (1CE1) to the first terminal block
