 4. Fault Isolation
_______________
 A. If the test gives the maintenance messages:
 AFS: CHK DMC 1 - FMGC 1 CKT (ISSUED BY: FG1) and
 AFS: CHK DMC 1 - FMGC 2 CKT (ISSUED BY: FG2)

 (1) Do the test given in Para. 3 with the EIS DMC selector switch (18WT) on the SWITCHING panel (8VU) at CAPT/3.
 (a) If the fault continues:
 - replace the PFD-CAPT (2WT1) (Ref. AMM TASK 31-63-22-000-001) and (Ref. AMM TASK 31-63-22-400-001).

 (2) If the fault continues:

 - replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).

 (3) If the fault continues:

 - do a check and repair the wiring of the PFD OWN VALID discrete from the DMC 1 (1WT1) to the first terminal block (Ref. ASM 22-85/04).
 B. If the test gives the maintenance messages:
 AFS: CHK DMC 2 - FMGC 2 CKT (ISSUED BY: FG2) and
 AFS: CHK DMC 2 - FMGC 1 CKT (ISSUED BY: FG1)

 (1) Do the test given in Para. 3 with the EIS DMC selector switch (18WT) on the SWITCHING panel (8VU) at F/O/3.

 (a) If the fault continues:
 - replace the PFD-F/O (2WT2) (Ref. AMM TASK 31-63-22-000-001) and (Ref. AMM TASK 31-63-22-400-001).

 (2) If the fault continues:

 - replace the DMC-2 (1WT2) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).

 (3) If the fault continues:

 - do a check and repair the wiring of the PFD OPP VALID discrete from the DMC 2 (1WT2) to the first terminal block (Ref. ASM 22-85/04).
 C. Do the test given in Para. 3.
