1 . If the IDG2 filter element is damaged or,
_ . If the filter element is bypassed (metal particles on the filter element) or, . If you think it was bypassed (filter not installed correctly, or filter O-ring damaged, or you are not sure that the filter element was bypassed) or, . If you smell a fuel odour from the filter element or the filter cover:
 - replace the IDG2 oil cooler (Ref. AMM TASK 73-11-60-000-002) and (Ref. AMM TASK 73-11-60-400-002).

 - clean the tubings of the external system:

 NOTE : Clean the tubings in a shop.
____
 a Remove the tubings (Ref. AMM TASK 24-21-49-000-003), (Ref.
_ AMM TASK 24-21-49-000-004), clean them, and install them (Ref. AMM TASK 24-21-49-400-003), (Ref. AMM TASK 24-21-49-400-004).
 2 If the filter element shows signs of contamination (contains
_ large metallic chips or shows signs of internal damage):
 - replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
 3 If the filter element does not show signs of contamination:
_
 - drain the oil (Ref. AMM TASK 12-13-24-680-040),

 - replace the IDG2 oil filter (Ref. AMM TASK 24-21-51-000-041) and (Ref. AMM TASK 24-21-51-400-041),

 - fill the IDG2 with oil (Ref. AMM TASK 12-13-24-612-041).

 a If the fault continues:
_
 - remove the wiring harness from IDG2 connector C and do a check for ground between the EGIU2 (22XU2) pin AA/5B, the GCU2 (1XU2) pin AA/15D and IDG2 wiring harness pin C/A (Ref. ASM 24-21/01).
 * If there is ground:
 - remove the EGIU2 and the GCU2 one after the other and do a check for ground:

 . if there is ground:

 - remove the EGIU1 and the GCU1 one after the other and do a check for ground:

 * if there is no ground:
 - replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002) or,

 - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).

 * if there is ground, repair the wiring.
 . If there is no ground:
 - replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
