 A. Test Do the BITE test of the VOR/MARKER (system 1) (Ref. AMM TASK 34-55-00-740-002).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message DMC1/2 (1WT1/2)/DDRMI (1FN)/VOR1 (3RS1):
 - do the SYSTEM TEST of the DMC1 (Ref. AMM TASK 31-60-00-740-004).
 (1) If the test gives a maintenance message related to a DMC1 fault:

 - replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).

 (2) If the test is OK:

 - remove the DMC1

 - do a check and repair the wiring between the DMC1 and the first terminal block: for pins AA/9C, 9D (Ref. ASM 34-55/01)

 - install the DMC1.

 B. Do the test given in Para. 3.

__________________
 A. Not applicable, you cannot confirm this fault on the ground.
 4. Fault Isolation
_______________
 A. If the fault symptom is identified by the crew observation, incorrect identification codes shown on the NDs:
 - do the functional test of the VOR/MKR (Ref. AMM TASK 34-55-00-720-001).
 (1) If the test is OK:
 - no maintenance action is required.
 NOTE : The display of incorrect identification codes on the NDs can

____ result from a bad transmission from the ground station.
 (2) If the test is not OK:
 - refer to the procedure (Ref. TASK 34-55-00-810-812) and (Ref. TASK 34-55-00-810-814) (para. fault isolation only).
