A. If the test confirms the fault:
- replace the EGIU-1 (22XU1) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
(1) If the fault continues:
- replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring between (Ref. ASM 24-21/01): . the pin AB/7 of the IDG1 (4000XU) and the pin AA/8A of the GCU1 (1XU1) . the pin AB/8 of the IDG1 (4000XU) and the pin AA/9B of the GCU1 (1XU1) . the pin AB/9 of the IDG1 (4000XU) and the pin AA/9A of the GCU1 (1XU1)
- do a check and repair the wiring between (Ref. ASM 24-22/02): . the pin AB/9A of the GCU1 (1XU1) and the pin AA/4C of the EGIU1 (22XU1) . the pin AB/9B of the GCU1 (1XU1) and the pin AA/4D of the EGIU1 (22XU1) . the pin AB/9C of the GCU1 (1XU1) and the pin AA/5A of the EGIU1 (22XU1). Then make sure that the ground wire is correctly connected to the pin AA/5C of the EGIU1 (22XU1).
- do a check and repair the wiring between (Ref. ASM 31-54/03): . the pin AA/1A of the EGIU1 (22XU1) and the pin AB/10G of the SADC1 (1WV1) . the pin AA/1B of the EGIU1 (22XU1) and the pin AB/10H of the SADC1 (1WV1) . the pin AA/1C of the EGIU1 (22XU1) and the pin AB/10G of the SADC2 (1WV2) . the pin AA/1D of the EGIU1 (22XU1) and the pin AB/10H of the SADC2 (1WV2)
