B. Test Do the ground scanning of the CFDIU (Ref. AMM TASK 31-32-00-740-003).
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS:CLOCK:
- replace the CLOCK (2FS), (Ref. AMM TASK 31-21-21-000-001) and (Ref. AMM TASK 31-21-21-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the clock (2FS) pins A/W, X to the first terminal block , (Ref. ASM 31-21/01).
B. Do the test given in Para. 3.B.

4. Fault Isolation
_______________
A. If the fault symptom is identified by GMT indication in amber crosses on the lower ECAM DU:
- open the circuit breaker 2TW.
- close the circuit breaker 2TW.
(1) If the circuit breaker trips:
- replace the CFDIU (1TW) (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(2) If the fault continues
- replace the CFDIU (1TW) (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
