Loss of the DME 1 Tuning Data
 1. Possible Causes
_______________
 - FMGC-1 (1CA1)

 - RMP-COM/NAV FREQ SEL, 1 (1RG1)

 - INTRG-DME, 1 (2SD1)

 - wiring of the FMGC OWN CB 1 bus from the FMGC 1 (1CA1) to the first
 terminal block

 - wiring of the DATA FROM FMGC bus from the COM/NAV FREQ SEL RMP 1 (1RG1) to the first terminal block

 - wiring of the NAV DATA OUTPUT bus from the COM/NAV FREQ SEL RMP 1 (1RG1) to the first terminal block

 - wiring of the FREQ FUNCT SELECT DATA INP A bus from the DME interrogator 1 (2SD1) to the first terminal block

_______________
 A. If the test gives the maintenance message FMGC1(1CA1)/RMP1(1RG1)/DME1(2SD1): - on the center pedestal, on the RMP 1, 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
 FMGC1(1CA1)/RMP1(1RG1)/ DME1(2SD1):

 - do the Interface test of the IR (system 1) (Ref. AMM TASK 34-14-00-740-001).
 (a) If the Interface test of the IR gives a maintenance message related of a FMGC 1 failure:
 - replace the FMGC-1 (1CA1) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
 1 If the fault continues:
_
 - do a check and repair the wiring of the FMGC OWN CB 1 bus from the FMGC 1 (1CA1) to the first terminal block (Ref. ASM 22-86/02).
 (b) If the Interface test of the IR does not give a maintenance message related of a FMGC 1 failure:
 - replace the RMP-COM/NAV FREQ SEL, 1 (1RG1) (Ref. AMM TASK 23-13-13-000-001) and (Ref. AMM TASK 23-13-13-400-001).
 1 If the fault continues:
_
 - do a check and repair the wiring of the DATA FROM FMGC bus from the COM/NAV FREQ SEL RMP 1 (1RG1) to the first terminal block (Ref. ASM 23-13/01).
 (2) If the test gives again the maintenance message
 FMGC1(1CA1)/RMP1(1RG1)/ DME1(2SD1):

 - do the BITE test of the VOR/MKR (Ref. AMM TASK 34-55-00-740-002).
 (a) If the BITE test gives a maintenance message related of a RMP 1 failure:
 - replace the RMP-COM/NAV FREQ SEL, 1 (1RG1) (Ref. AMM TASK 23-13-13-000-001) and (Ref. AMM TASK 23-13-13-400-001).
 1 If the fault continues:
_
 - do a check and repair the wiring of the NAV DATA OUTPUT bus from the COM/NAV FREQ SEL RMP 1 (1RG1) to the first terminal block (Ref. ASM 34-51/01).
 (b) If the BITE test does not give a maintenance message related of a RMP 1 failure:
 - replace the INTRG-DME, 1 (2SD1) (Ref. AMM TASK 34-51-33-000-001) and (Ref. AMM TASK 34-51-33-400-001).
