4. Fault Isolation
_______________
A. If the test gives the maintenance message NO RADAR 1 DATA:
- replace the CFDIU (1TW), (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(1) If the fault continues:
- replace the XCVR-WEATHER RADAR, 1 (1SQ1), (Ref. AMM TASK 34-41-33-000-004) and (Ref. AMM TASK 34-41-33-400-003).
(a) If the fault continues:
- do a check and repair the wiring from the CFDIU (1TW) to the weather radar transceiver 1 (1SQ1) from pins AA/11B, 11C to pins AB/1J, 1K , (Ref. ASM 31-32/02).
B. Do the test given in Para. 3.B.
