- do this trouble shooting procedure (Ref. TASK 27-90-00-810-824).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
R B ELEV MODE XDCR 34CE4
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-933) related
to the ANI 7-X analog input signal of the ELAC MON and SEC MON (Ref. R ASM 27-93/08) and (Ref. ASM 27-94/08).
(1) If the fault continues:
- replace the mode selector valve transducer of the servocontrol (34CE4) (Ref. AMM TASK 27-34-51-000-006) and (Ref. AMM TASK 27-34-51-400-005).
NOTE : The resistance of primary and secondary windings must be
____
between 30 ohms and 500 ohms.
(2) If the fault continues:
(a) Do a check of the wiring of the MODE XDCR SPLY signal from the servocontrol (34CE4) 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) Repair the wiring of the MODE XDCR V1 signal from the servocontrol (34CE4) to the first terminal block (Ref. ASM 27-93/08).
B. Do the tests given in Para. 3.
Loss of the Right Blue Elevator-Servocontrol Mode-Transducer by the SEC 2

_______________
- SEC-2 (1CE2)
- wiring of the R B SERVO CTL MODE POS (ANI 7-2) from the SEC 2 (1CE2) MON part to the first terminal block

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).
(a) If the ground scanning gives the maintenance message: SEC2 OR WIRING FROM R B ELEV MODE XDCR 34CE4
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the list below: SEC2 OR WIRING FROM L B ELEV MODE XDCR 34CE3 SEC2 OR WIRING FROM L ELEV POS MON XDCR SEC2 OR WIRING FROM R B ELEV MODE XDCR 34CE4 SEC2 OR WIRING FROM R ELEV POS MON XDCR SEC2 MON OR INPUT OF THS ACTR XDCR3 9CE
