(1) If the wiring is not correct:
- repair it.
(2) If the wiring is correct:
- do a check of the resistance between the pins B/7 and B/8, then between the pins B/8 and B/9 of the IDG 1.
NOTE : The normal value is 99.1 Ohms plus or minus 5 Ohms at 25.C.
____
(a) If the oil-out bulb resistance is less than the oil-in bulb resistance:
- replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
(b) If the oil-out bulb resistance is not less than the oil-in bulb resistance:
- replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).

A. Test
Not applicable.
NOTE : The BITE test permits to do a check of the GCU only. The fault
____ confirmation related to IDG 2 BULB TOLERANCE is not possible on ground.
4. Fault Isolation
_______________
CAUTION : BEFORE YOU START THE CHECK OF IDG WIRING THAT INCLUDES CONNECTORS,
_______ EXAMINE EACH CONNECTOR TO MAKE SURE THAT THERE IS NO OIL IN IT. IF YOU FIND OIL, CLEAN THE CONNECTOR AND CONNECT IT AGAIN. IF THE FAILURE CONTINUES, DO THE TROUBLE SHOOTING PROCEDURE AS GIVEN BELOW.
A. If the fault symptom is identified by the CFDS message IDG 2 BULB TOLERANCE and the upper ECAM DU warning IDG 1 OIL OVHT:
- do a check of the wiring: . for open circuit between the GCU 2 pin A/9A and the IDG 2 pin B/9 . for short to ground between the GCU 2 pin A/8A and the IDG 2 pin B/7 . for wire cross-connection between respectively the GCU 2 pins A/8A, A/9A, A/9B and the IDG 2 pins B/7, B/9, B/8 (Ref. ASM 24-21/01).
