R A. If the fault symptom is identified by the CFDS message IDG1 (E1-4000XU)
R PMG/ GCU1 (1XU1) and the upper ECAM-DU warning GEN 1 FAULT:
R (1) If the CFDS message comes into view with the fault codes 104 (UV TRIP
R / SOPMG keyword), 187 (PMG OPEN / SHORT keyword) or 260 (UF TRIP /
R SOPMG keyword):
R - do a check of the resistance of the IDG 1 PMG stator (Ref. ASM 24-R 22/01) between:
R . pins B/12 and B/13 (1 ohm plus or minus 0.05 ohm)
R . pins B/12 and B/14 (1 ohm plus or minus 0.05 ohm)
R . pins B/13 and B/14 (1 ohm plus or minus 0.05 ohm).
R (a) If the resistance values are out of the specified limits:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-R 040) and (Ref. AMM TASK 24-21-51-400-040).
R (b) If the resistance values are in the specified limits:
R - do a check of the wiring of the IDG 1 PMG stator (Ref. ASM 24-R 22/01) for a short circuit, an open circuit, a short to ground
R or a short to shield between:
R . pin B/12 of the IDG 1 and pin C/10 of the GCU 1
R . pin B/13 of the IDG 1 and pin C/11 of the GCU 1
R . pin B/14 of the IDG 1 and pin C/9 of the GCU 1
R . pins C/10, C/11, C/9 and pin C/7 of the GCU 1 (short to R shield of the PMG wiring).
R 1_ If the wiring is not correct:
R - repair or replace as necessary.
R 2_ If the wiring is correct:
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001)
R and (Ref. AMM TASK 24-22-34-400-001).
R a_ If the fault continues:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-R 51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
R (2) If the CFDS message comes into view with the fault code 189 (PMG SHT
R TO CHAS keyword):
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001) and (Ref.
R AMM TASK 24-22-34-400-001).
R (a) If the fault continues:
R - do a check of the wiring of the IDG 1 PMG stator (Ref. ASM 24-R 22/01) for a short circuit, an open circuit, a short to ground
R or a short to shield between:
R . pins C/10 and C/7 of the GCU 1
R . pins C/11 and C/7 of the GCU 1
R . pins C/9 and C/7 of the GCU 1.
R 1_ If the wiring is not correct:
R - repair or replace as necessary.

R 2 If the wiring is correct:_
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-
R 000-040) and (Ref. AMM TASK 24-21-51-400-040).

R (1) Aircraft Maintenance Configuration
R (a) Energize the aircraft electrical circuits
