__________________
 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
