 3. Fault Confirmation
__________________
 A. Test
 (1) Do the operational test of the ADF (Ref. AMM TASK 34-53-00-710-002).
 4. Fault Isolation
_______________
 A. If on the two NDs:
 . the ADF 2 data do not come into view
 . the red flag is shown:

 - do the BITE test of the ADF (Ref. AMM TASK 34-53-00-740-003).
 (1) If the BITE test gives a maintenance message:
 - Do the trouble shooting procedure related to the maintenance message.

 May 01/05R CES

 (2) If the BITE test does not give a maintenance message:
 - replace the RECEIVER-ADF, 2 (2RP2) (Ref. AMM TASK 34-53-31-000-002) and (Ref. AMM TASK 34-53-31-400-002).
 (a) If the fault continues:
 - do a check and repair the wiring of the BEARING OUTPUT 2 bus from the ADF receiver 2 (2RP2) to the first terminal block (Ref. ASM 34-53/01).
 B. If on the CAPT ND only: . the ADF 2 data do not come into view . the red flag is shown:
 - make sure that on the center pedestal, on the SWITCHING panel 8VU, the EIS DMC selector switch is at CAPT 3:
 (1) If no:

 - replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the ADF 2 INPUT bus from the DMC 1 (1WT1) to the first terminal block (Ref. ASM 34-53/01).

 (2) If yes:

 - replace the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the ADF 2 INPUT bus from the DMC 3 (1WT3) to the first terminal block (Ref. ASM 34-53/01).
 C. If on the F/O ND only: . the ADF 2 data do not come into view . the red flag is shown:
 - make sure that on the center pedestal, on the SWITCHING panel 8VU, the EIS DMC selector switch is at F/O 3:
 (1) If no:
 - replace the DMC-2 (1WT2) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the ADF 2 INPUT bus from the DMC 2 (1WT2) to the first terminal block (Ref. ASM 34-53/01).

 - replace the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the ADF 2 INPUT bus from the DMC 3 (1WT3) to the first terminal block (Ref. ASM 34-53/01).
