- Do the trouble shooting procedure related to the maintenance message.

 (2) If the test does not give a maintenance message:

 - replace the RECEIVER-VOR/MKR, 1 (3RS1) (Ref. AMM TASK 34-55-31-000-001) and (Ref. AMM TASK 34-55-31-400-001).
 (a) If the fault continues:
 - replace the ANTENNA-VOR 1/2 (4RS) (Ref. AMM TASK 34-55-11-000-001) and (Ref. AMM TASK 34-55-11-400-001).

 May 01/05 CES 1 If the fault continues:

_
 - do a check and repair the wiring from the VOR 1/2 antenna
 (4RS) to the VOR/MKR receiver 1 (3RS1) (Ref. ASM 34-55/01) R and (Ref. ESPM 204416).
 B. Do the test given in Para. 3.

 A. Test Do the functional test of the VOR/MKR (Test of the VOR reception and identification) (Ref. AMM TASK 34-55-00-720-001).
 4. Fault Isolation
_______________
 A. If on the two NDs:
 . the VOR 2 data do not come into view
 . the red flag is shown:

 - do the BITE test of the VOR/MKR (Ref. AMM TASK 34-55-00-740-002).
 (1) If the BITE test gives a maintenance message: R - Do the trouble shooting procedure related to the maintenance R message. R
