 A. If the test gives the maintenance message DMC1/2
 (1WT1/2)/DDRMI(1FN)/DME1(2SD1):

 - do the EIS system test (for 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 does not give a maintenance message related to a DMC1 fault:

 - remove the DMC1

 - do a check and repair the wiring between the DMC1 and the first terminal block: for pins AA/7A, 7B of the DMC1 (Ref. ASM 34-51/01)

 - install the DMC1.

 B. Do the test given in Para. 3.

 Loss of the DME Antenna 2 Signals
 1. Possible Causes
_______________
 - INTRG-DME, 2 (2SD2)

 - ANTENNA-DME, 2 (3SD2)

 - wiring between the DME interrogator 2 and the DME antenna 2

 4. Fault Isolation
_______________
 A. If the test gives the maintenance message DME2 ANTENNA (3SD2):
 - swap the INTRG-DME, 2 (2SD2) and the DME interrogator 1 (Ref. AMM TASK 34-51-33-000-001) and (Ref. AMM TASK 34-51-33-400-001).
 (1) If the fault stops:

 - replace the DME interrogator that you installed on side 1.

 (2) If the fault continues:

 - remove the DME interrogator 2

 - disconnect the coaxial connector from the DME antenna 2 (Ref. AMM TASK 34-51-11-000-002)

 - do a check of the wiring between the DME interrogator 2 and the DME antenna 2: for pin AB/C of the DME interrogator 2 (Ref. ASM 34-51/01).
