A. If the test gives the maintenance message: WXR2 (1SQ2) BUS HAZARD/GPWC (1WZ) - If the second weather radar is not installed: . set the system switch to 1, the message goes out of view. - If the second weather radar is installed: . replace the GPWC (1WZ) (Ref. AMM TASK 34-48-34-000-001) and (Ref. AMM TASK 34-48-34-400-001).
(1) If the fault continues: - replace the XCVR-WEATHER RADAR, 2 (1SQ2) (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 of the RADAR 2 DATA INPUT bus from the weather radar transceiver 2 to the GPWC: from pins AB/5J, 6J to pins AB/6C, 6D (Ref. ASM 34-48/02).
B. Do the test given in Para. 3.
