3. Fault Confirmation
__________________
A. Test
Not applicable.
NOTE : As the GEN 1 was set to OFF because of a true failure, the fault
____
confirmation is not necessary.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the CFDS message IDG 1 LOW OIL PRESSURE and the upper ECAM DU warning IDG 1 OIL LO PR:
NOTE : You can find this message with other CFDS fault messages. Do this
____
trouble shooting procedure first.
- do a check of the IDG1 oil level (Ref. AMM TASK 24-21-00-210-046).
(1) If the oil level is low:
- do a visual inspection of the IDG1 and external system (tubings, cooler) for oil leaks (Ref. AMM TASK 24-21-00-210-047).
(a) If you find no leak:
- add oil (Ref. AMM TASK 12-13-24-612-041).
(2) If the oil level is correct:
- do a check of the Differential Pressure Indicator (DPI) of the IDG1 (Ref. AMM TASK 24-21-00-210-046).
(a) If the DPI is extended:
- do the alternate procedure (Ref. TASK 24-21-00-810-815).
(b) If the DPI is not extended:
- do an inspection of the IDG1 filter element (Ref. AMM TASK 24-21-00-210-044).

1 . If the IDG1 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 IDG1 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 IDG1 oil filter (Ref. AMM TASK 24-21-51-000-041) and (Ref. AMM TASK 24-21-51-400-041),
- fill the IDG1 with oil (Ref. AMM TASK 12-13-24-612-041).
a If the fault continues:
_
- remove the wiring harness from IDG1 connector C and do a check for ground between the EGIU1 (22XU1) pin AA/5B, the GCU1 (1XU1) pin AA/15D and IDG1 wiring harness pin C/A (Ref. ASM 24-21/01).
. 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-1 (22XU1) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002) or,
- the GCU-1 (1XU1) (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).
