A. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
ELAC1 OR WIRING FROM FAC1/2 or
ELAC2 OR WIRING FROM FAC1/2
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-932) related to the DSI 15/18 output discret digital signal of the ELAC 1 and ELAC 2 (Ref. ASM 27-92/37).
B. Do the test given in Para. 3.
