A. Test
(1) On the FCU, make sure that the A/THR pushbutton switch is pushed.
(2) Do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FMGC 1.
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS: FMGC1/ATHR2 ENG WIRG:
- replace the FMGC-1 (1CA1), (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the ATH OPP ENGD COM OPP and ATH OPP ENGD MON OPP discretes (from the FMGC 1 (1CA1) to the first terminal block) (Ref. ASM 22-31/01).
