(Activation for the BITE Test)
AMM 27-96-00-740-001 BITE Test of the EFCS (Ground Scanning)
ASM 27-94/08
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).
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).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
SEC2 MON OR WIRING TO L G ELEV SERVO VLV 34CE1
- replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
(a) Replace the XDCR UNIT-ELEV POS, L (49CE1) (Ref. AMM TASK 27-92-13-000-001) and (Ref. AMM TASK 27-92-13-400-001).
(2) If the fault continues:
- replace the servovalve of the servocontrol 34CE1 (Ref. AMM TASK 27-34-51-000-008) and (Ref. AMM TASK 27-34-51-400-003).
(3) 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).
(4) If the fault continues:
(a) Do a check of the wiring of the SV XDCR V1 signal from the servocontrol (34CE1) to the SEC 2 (1CE2) (Ref. ASM 27-94/08):
- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.
(b) Do a check of the wiring of the SV XDCR SPlY signal from the servocontrol (34CE1) to the first te minal block (Ref. ASM 27-94/08).
- if there is continuity, see Para. (c)
- if there is no continuity, repair the above wiring.
(c) Repair the wiring of the POS XDCR MON signal from the transducer unit (49CE1) to the SEC 2 (1CE2) (Ref. ASM 27-94/08).
B. Do the tests given in Para. 3.

Failure of the Left Green Elevator-Servocontrol Mode-Transducer
1. Possible Causes
_______________
- mode selector valve transducer of the servocontrol (34CE1)
- wiring of the MODE XDCR SPLY signal from the servocontrol (34CE1) to the first terminal block
- wiring of the MODE XDCR V1 signal from the servocontrol (34CE1) 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).
(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 MODE XDCR 34CE1
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the list below: L ELEV POS MON XDCR OF ELAC1/SEC1 L G ELEV MODE XDCR 34CE1 R B ELEV POS MON XDCR OF ELAC1/SEC1
