_______________
A. If you cannot start the WR1 test on the MCDU:
- do a check for ground at pin AB/10K of the weather radar transceiver 1 (1SQ1).
(1) If there is no ground:
- replace the XCVR-WEATHER RADAR, 1 (1SQ1) (Ref. AMM TASK 34-41-33-000-004) and (Ref. AMM TASK 34-41-33-400-003).

- replace the LGCIU-2 (5GA2) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(a) If there is still ground:
- do a check and repair the wiring of the GROUND AIR discrete from the LGCIU2 (5GA2) to the weather radar transceiver 1 (1SQ1) (Ref. ASM 34-41/01).
