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 FCDC2 SDI INPUTS:
- replace the FCDC-2 (3CE2) (Ref. AMM TASK 27-95-34-000-001) and (Ref. AMM TASK 27-95-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the PIN PROGRAM (DSI 11/5 and DSI 12/5) signal from the FCDC2 (3CE2) to the ground terminal (Ref. ASM 27-95/05).
B. Do the test given in Para. 3. R
