R (1) If the resistance values are out of the specified limits:
R - replace the engine 1 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 - do a check of the wiring of the outlet oil temperature-sensor (Ref.
R ASM 24-21/01) for an open circuit, a short to ground or a short to
R shield condition between:
R . pin B/7 of the IDG 1 and pin A/9C of the GCU 1
R . pin B/8 of the IDG 1 and pin A/9D of the GCU 1
R . pins A/9C and A/10D of the GCU 1
R . pins A/9D and A/10D of the GCU 1.
R (a) If the wiring is not correct:
R - repair or replace as necessary.
R (b) If the wiring is correct:
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001) and
R (Ref. AMM TASK 24-22-34-400-001).
R 1 If the fault continues:_
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 B. When you replace a component or repair the wiring:
R - do the subsequent flight before you do the check of the Class 3 Faults
R of the GAPCU from the CFDS to make sure that the system operates
R correctly.
R If the test continues to give the fault message, continue the trouble
R shooting procedure.

_______________
R CAUTION : BEFORE YOU START THE CHECK OF IDG WIRING THAT INCLUDES CONNECTORS,
_______ R EXAMINE EACH CONNECTOR TO MAKE SURE THAT THERE IS NO OIL IN IT. R IF YOU FIND OIL, CLEAN THE CONNECTOR AND CONNECT IT AGAIN. R IF THE FAILURE CONTINUES, DO THE TROUBLE SHOOTING PROCEDURE AS R GIVEN BELOW.
R A. If the Class 3 Faults gives the maintenance message IDG2 (E2-4000XU) OIL
R OUT TEMP/ GCU2 (1XU2):
R - do an electrical resistance test of the outlet oil temperature-sensor
R of the IDG 2 between pins B/7 and B/8 (100 ohms plus or minus 10 ohms
R at the ambient temperature of the IDG case) (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).
