_______________
 A. If the test gives the maintenance message DMC2/1
 (1WT2/1)/DDRMI(1FN)/DME2(2SD2):

 - 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

 - do a check and repair the wiring between the DME interrogator 2 and the first terminal block: for pins AB/3G, 3H of the DME interrogator 2 (Ref. ASM 34-51/01)
