A. Test
(1) Do the functional test of the VOR/MKR (Ref. AMM TASK 34-55-00-720-001).
4. Fault Isolation
_______________
A. If there is no audio signal on the loud speakers during the test, when the MKR data are shown on the PFD:
- replace the RECEIVER-VOR/MKR, 1 (3RS1) (Ref. AMM TASK 34-55-31-000-001) and (Ref. AMM TASK 34-55-31-400-001).
(1) If the fault continues:
- replace the AMU (1RN) (Ref. AMM TASK 23-51-34-000-001) and (Ref. AMM TASK 23-51-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring of the MARKER AUDIO bus from the AMU (1RN) to the VOR/MKR receiver 1 (3RS1) (Ref. ASM 34-55/01).
B. Do the test given in Para. 3.
