- do the operational test of the LAND CAT III capability (Ref. AMM TASK 22-97-00-710-001)
- do the Ground Scanning of the AFS (Ref. AMM TASK 22-91-00-710-001).
(1) If there is one or several CFDS messages related to the AFS: R - do the trouble shooting procedure related to the maintenance R message. R R For defective LRU(s), see the Fault Symptoms List..

(2) If there is no CFDS message: - do a check on the Post Flight Report for other CFDS messages related to:
- Radio Altimeter System (via the FMGC), - ADIRS System, - Landing Gear Extension/Retractation System, - Slats/Flaps System.
R R R (a) If there is one or several CFDS messages: - do the trouble shooting procedure related to the maintenance message.
R For defective LRU(s), see the Fault Symptoms List..
R R (b) If there is no CFDS message, no trouble shooting is necessary except if the warning appears at the takeoff phase: - do the lubrification of the MLG (torque link and gland housing) (Ref. AMM TASK 12-22-32-640-001). If fault continues:
- check the hydraulic level (A/C on jacks) and the pressurization of the MLG shock absorber (Ref. AMM TASK 12-14-32-614-003) and (Ref. AMM TASK 12-12-32-611-004).
B. If the fault continues:
- replace the FAC-1 (1CC1) or/and FAC-2 (1CC2) and (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 OWN bus and the FAC HLTY MON (OWN & OPP) discretes between the FACs and the FWCs: (Ref. ASM 22-65/01) (Ref. ASM 22-69/01).
C. Do the test gives in Para 3.

C. Test
(1) Open the circuit breaker 5CC1 for more than 5 seconds.
(2) After 10 seconds, close the circuit breaker 5CC1.
(3) After 2 minutes, do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FAC 1.
