4. Fault Isolation
_______________
A. If the test gives the maintenance message NO AEVC DATA:
- replace the CFDIU (1TW) (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(1) If the fault continues:
- replace the AEVC (10HQ) (Ref. AMM TASK 21-26-34-000-001) and (Ref. AMM TASK 21-26-34-400-001).

(2) If the fault continues:
- do a check and repair the wiring from the CFDIU (1TW) to the AEVC (10HQ) from pins AA/3D, 3E to pins AB/13A, 14A (Ref. ASM 31-32/06).
B. Do the test given in Para. 3.B.
