Control (Activation for BITE Test) R AMM 27-96-00-740-001 BITE Test of the EFCS (Ground Scanning) ASM 27-93/12
3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the THS actuator electrical control (Ref. AMM TASK 27-96-00-710-022).
NOTE : Do the ground setting only with the ELAC 1.
____
(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: ELAC1 COM OR WIRING FROM THS ACTR XDCR2 9CE
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the two lists below: First list:
- ELAC1 COM OR WIRING FROM THS ACTR XDCR2 9CE
- ELAC1 OR WIRING FROM L B ELEV POS XDCR 34CE3
- ELAC1 OR WIRING FROM R B ELEV POS XDCR 34CE4 Second list:
- ELAC1 MON OR WIRING FROM THS ACTR XDCR2 9CE

- ELAC1 OR WIRING FROM L ELEV POS MON XDCR
- ELAC1 OR WIRING FROM R ELEV POS MON XDCR
- ELAC1 OR WIRING FROM L G ELEV MODE XDCR 34CE1
- ELAC1 OR WIRING FROM R Y ELEV MODE XDCR 34CE2
1_ First case:
Combination of maintenance messages of the first list, do this
trouble shooting procedure (Ref. TASK 27-90-00-810-811).
2_ Second case:
Combination of maintenance messages of the second list, do
this trouble shooting procedure (Ref. TASK 27-90-00-810-812).
3_ Third case:
Combination of maintenance messages of the first and second
lists, do this trouble shooting procedure (Ref. TASK 27-90-00-
810-813).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message: ELAC1 COM OR WIRING FROM THS ACTR XDCR2 9CE
- replace the ELAC-1 (2CE1), (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 from the ANI 2-3 XDCR COM signal of the ELAC 1 (2CE1) to the first terminal block, (Ref. ASM 27-93/12).
B. Do the tests given in Para. 3.
