R B. If the BITE test gives the message TEST PASSED:
R - do an electrical resistance test of the IDG 2 disconnect solenoid for
R an open circuit or a high resistance condition between pin A/12 and pin
R A/13 of the IDG 2 (3 ohms plus or minus 1 ohm) (Ref. ASM 24-21/01).
R (1) If the resistance values are out of the specified limits:
R - replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040)
R and (Ref. AMM TASK 24-21-51-400-040).
R (2) If the resistance values are in the specified limits:
R - replace the RELAY-IDG 2 DISC CTL (4XT)
R - do a dynamic disconnect test of the IDG 2 (Ref. AMM TASK 24-21-00-R 720-041).
R (a) If the test is OK:
R - stop the trouble shooting.
R (b) If the test is not OK:
R - do a check of the wiring for an open circuit or a short to
R ground between pin A1 of the IDG 2 disconnect control relay
R (4XT) and pin A/12 of the IDG 2 (Ref. ASM 24-21/01).
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-2 (1XU2) (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 2 IDG (4000XU) (Ref. AMM TASK 24-21-R 51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
R C. Do the test given in para. 3.

R and the upper ECAM-DU warning GEN 1 FAULT:
R (1) If one of these CFDS messages:
R - IDG1 (E1-4000XU) OIL OUT TEMP/ GCU1 (1XU1)
R - IDG1 (E1-4000XU) LOW OIL PRESSURE
R comes into view with IDG1 (E1-4000XU), do the trouble shooting for
R these messages first:
