__________________
A. Test
(1) Do the functional test of the DME (Ref. AMM TASK 34-51-00-720-001).
4. Fault Isolation
_______________
A. If the DME 1 data do not come into view on the ND:
- do the BITE test of the DME (Ref. AMM TASK 34-51-00-740-002).
(1) If the test gives a maintenance message: R - Do the trouble shooting procedure related to the maintenance R message. R
(2) If the test does not give a maintenance message:
- replace the INTRG-DME, 1 (2SD1) (Ref. AMM TASK 34-51-33-000-001) and (Ref. AMM TASK 34-51-33-400-001).
(a) If the fault continues:
- replace the ANTENNA-DME, 1 (3SD1) (Ref. AMM TASK 34-51-11-000-002) and (Ref. AMM TASK 34-51-11-400-002).
1 If the fault continues:
_
- do a check and repair the wiring from the DME antenna 1 (3SD1) to the DME interrogator 1 (2SD1) (Ref. ASM 34-51/01).
B. Do the test given in Para. 3.

_______________
A. If the test gives the maintenance message FMGC2(1CA2)/RMP2(1RG2)/DME2(2SD2): - on the center pedestal, on the RMP 2, push the NAV and the VOR
pushbutton switches (the green LED on these pushbutton switches comes on)
- do the BITE test of the DME (Ref. AMM TASK 34-51-00-740-002).
(1) If the test does not give the maintenance message
FMGC2(1CA2)/RMP2(1RG2)/ DME2(2SD2):
