- do a visual check on the oil sight glass on the accessory drive gearbox and make sure that the oil level in the APU oil reservoir is sufficient.
(1) If the oil level is not sufficient:
- do the oil servicing (Ref. AMM TASK 49-90-00-600-004).
- calculate the APU oil consumption.
(a) If there is a sudden increase in the APU oil consumption:
- carefully examine the APU externally and make sure that you do not find leaks on the oil system components or oil lines.

Config-2 Aug 01/05 CES 1 If you find external oil leaks:
_
- correct/replace as necessary.
2 If you do not find external oil leaks:
_ - examine the APU for internal oil leaks. a If the fault continues:
_
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-003) and (Ref. AMM TASK 49-11-11-400-003).
(b) If the oil level is sufficient:
- do a check and repair the wiring from the ECB (59KD) AB/H2, J4 to the OIL LEVEL SENSOR (8089KM) P8/1, 2, (Ref. ASM 49-61/02).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002)
B. Do the test given in para. 3.
