AMM 27-96-00-740-001 BITE Test of the EFCS (Ground Scanning)
ASM 27-93/08
3. Fault Confirmation
__________________
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: ELAC2 OR WIRING FROM R Y ELEV MODE XDCR 34CE4
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the two lists below: First list:
- ELAC2 COM OR INPUT OF THS ACTR XDCR1 9CE
- ELAC2 OR WIRING FROM L G ELEV POS XDCR 34CE1
- ELAC2 OR WIRING FROM R Y ELEV POS XDCR 34CE2 Second list:
- ELAC2 MON OR INPUT OF THS ACTR XDCR1 9CE
- ELAC2 OR WIRING FROM L ELEV POS MON XDCR
- ELAC2 OR WIRING FROM R ELEV POS MON XDCR

Feb 01/03R CES
- ELAC2 OR WIRING FROM L B ELEV MODE XDCR 34CE3
- ELAC2 OR WIRING FROM R Y ELEV MODE XDCR 34CE4
1_ First case:
Combination of maintenance messages of the first list, do this
trouble shooting procedure (Ref. TASK 27-90-00-810-814).
2_ Second case:
Combination of maintenance messages of the second list, do
this trouble shooting procedure (Ref. TASK 27-90-00-810-815).
3_ Third case:
Combination of maintenance messages of the first and second
lists, do this trouble shooting procedure (Ref. TASK 27-90-00-
810-816).
4. Fault Isolation
_______________
A. If the test gives the maintenance message: ELAC2 OR WIRING FROM R B ELEV MODE XDCR 34CE4
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the MODE XDCR (ANI 7-2) signal from the ELAC 2 (2CE2) MON part to the first terminal block (Ref. ASM 27-93/08).
B. Do the tests given in Para. 3.
