1_ If the fault continues:
 - remove the weather radar transceiver 1
 - remove the radio altimeter transceiver 1
 - do a check and repair the wiring from the radio altimeter
 transceiver 1 to the weather radar transceiver 1: from pins
 AB/2G, 3G to pins AB/1C, 2C (Ref. ASM 34-41/02)
 - install the weather radar transceiver 1
 - install the radio altimeter transceiver 1.

 (b) If the CLASS 3 FAULTS report gives the maintenance message RA2(2SA2)/WXR1(1SQ1):
 - replace the XCVR-RA, 2 (2SA2) (Ref. AMM TASK 34-42-33-000-001) and (Ref. AMM TASK 34-42-33-400-001).
