A. If the test gives the maintenance message HF 2 NO DATA FROM CFDIU:
- replace the XCVR-HF, 2 (3RE2) (Ref. AMM TASK 23-11-33-000-001) and (Ref. AMM TASK 23-11-33-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the BUS 2 OUTPUT signal,(from the HF 2 transceiver (3RE2) pins AB/4A, 4B to the first terminal block)(Ref. ASM 31-32/03).
