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).

B. Do this operational test to make sure that the system operates correctly.
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(2) On the ELEC panel 35VU:
- push, release and push again the GEN 2 pushbutton switch (3XU2).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 2 (Ref. AMM TASK 71-00-00-710-003).
C. Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the ECAM control panel: On the lower ECAM display unit:
- push the ELEC key to get the ELEC - the correct electrical parameters of
page. GEN 2 are shown and the AC 2 busbar is supplied by the GEN 2.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 2 (Ref. AMM TASK 71-00-00-710-028).
(2) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
