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 test gives the maintenance message CHECK GCU2 PIN A9A, A9B IDG2 PIN B9, B8 WIRING:
- do a check of the wiring for open circuit or short to ground between respectively the IDG 2 pins B/9, B/8 and the GCU 2 pins A/9A, A/9B (Ref. ASM 24-21/01).
(1) If the wiring is not correct:
- repair it.

201-299, 301-399, Aug 01/05 CES (2) If the wiring is correct:
- do a check of the resistance between the pins B/8 and B/9 of the IDG 2.
NOTE : The normal value is 99.1 Ohms plus or minus 5 Ohms at 25.C.
____
(a) If the resistance value is out of the specified limits:
- replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
(b) If the resistance value is in the specified limits:
- replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
B. Do the test given in Para. 3.

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 1 BULB TOLERANCE and the upper ECAM DU warning IDG 1 OIL OVHT:
- do a check of the wiring: . for open circuit between the GCU 1 pin A/9A and the IDG 1 pin B/9 . for short to ground between the GCU 1 pin A/8A and the IDG 1 pin B/7 . for wire cross-connection between respectively the GCU 1 pins A/8A, A/9A, A/9B and the IDG 1 pins B/7, B/9, B/8 (Ref. ASM 24-21/01).
