A. If the test gives the maintenance message DMC3 : NO RA1 DATA:
- replace the XCVR-RA, 1 (2SA1) (Ref. AMM TASK 34-42-33-000-001) and (Ref. AMM TASK 34-42-33-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the ALTITUDE BUS 2 from the RA transceiver 1 (2SA1) to the first terminal block (Ref. ASM 34-42/01).
