4. Fault Isolation
_______________
A. If the test gives the maintenance message NO HF2 DATA:
- 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:
- replace the CFDIU (1TW) (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring from the HF 2 transceiver (3RE2) to the CFDIU (1TW) (Ref. ASM 23-11/02).
B. Do the test given in Para. 3.B.
