A. If the test gives the maintenance message AFS : CHK ADIRU 1/2/3 (ISSUED BY : FAC 1):
- replace the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(1) If the fault continues:
- do a check and repair the wiring of the ADC SW and ATT SW discretes (from the FAC 1 (1CC1) to the first terminal block) (Ref. ASM 22-68/01).

3. Fault Confirmation
__________________
A. Test
(1) Do the operational tests of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FAC 1:
(a) with the FLT CTL/FAC1 pushbutton switch (12CC1) released.
(b) with the FLT CTL/FAC1 pushbutton switch (12CC1) pushed.
4. Fault Isolation
_______________
A. If only the first test gives the maintenance message AFS: FAC1/P-B SW 12CC1:
- replace the FAC-1 (1CC1), (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(1) If the fault continues:
- do a check and repair the wiring of the FAC ENGD SW COM and FAC ENGD SW MON discretes (from the FAC 1 (1CC1) to the FLT CTL/FAC 1 pushbutton switch (12CC1)), (Ref. ASM 22-65/01).
