__________________
A. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-
00-740-001). R
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
ELAC2 COM OR BUS2 FROM ADR1
- 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 DGI 07 signal from the ELAC 2 (2CE2) to the first terminal block, COM part only (Ref. ASM 27-92/52).
R (2) If the fault continues:
R - do the following trouble shooting procedures.
R (a) Airspeed Discrepancy on the PFD or on the Standby Airspeed
R Indicator (Ref. TASK 34-11-00-810-870)
R (b) Altitude or Airspeed Discrepancy between CAPT PFD and F/O PFD
R (Ref. TASK 34-13-00-810-998)
R (c) Different Angle of Attack Value on the three ADIRUs (Ref. TASK
R 34-11-00-810-861).
B. Do the test given in Para. 3.
Loss of the ADR 2 BUS 3 for the ELAC 1
1. Possible Causes
_______________
- ELAC-1 (2CE1)
- wiring of the DGI 07 signal from the ELAC 1 (2CE1) to the first terminal block
