(a) Check the wiring of the WXR1 OUTPUT BUS from the DMC1 (1WT1) pins AB/14B, 14C to the FO ND DU (3WT2) (Ref. ASM 31-61/00)
(b) Check the wiring between the DMC1 (1WT1) and the WEATHER RADAR-XCVR 1 (1SQ1) and the WEATHER RADAR-XCVR 2 (1SQ2) (Ref. ASM 31-62/00) (Ref. ASM 34-41/00)
- install the DMC1 (1WT1) (Ref. AMM TASK 31-63-34-400-001)
- install the FO ND DU (3WT2) (Ref. AMM TASK 31-63-22-400-001)

(2) If the fault continues:
- replace the XCVR-WEATHER RADAR, 1 (1SQ1) (Ref. AMM TASK 34-41-33-000-004) (Ref. AMM TASK 34-41-33-400-003)
(3) If the fault continues:
- remove the DMC1 (1WT1) (Ref. AMM TASK 31-63-34-000-001)
- remove the FO ND DU (3WT2) (Ref. AMM TASK 31-63-22-000-001)
- remove the WEATHER RADAR-XCVR1 (1SQ1) (Ref. AMM TASK 34-41-33-000-004)
(a) Check the wiring of the WXR1 OUTPUT BUS from the DMC1 (1WT1) pins AB/14B, 14C to the FO ND DU (3WT2) (Ref. ASM 31-61/00)
