(2) If the operational test of the automatic change-over function does not give the maintenance message AFS: FAC2/RT ENGD CHG-OV:
- replace the FAC-1 (1CC1), (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(a) If the fault continues:
- do a check and repair the wiring of the RUD TR OWN ENGD COM and RUD TR OWN ENGD MON discretes (from the FAC 1 (1CC1) to the first terminal block), (Ref. ASM 22-68/03).
B. Do the test given in Para. 3.A.(1).
