3. Fault Confirmation__________________
A. Do the self test of the ECB (59KD) (Ref. AMM TASK 49-00-00-710-001).
4. Fault Isolation
_______________
**ON A/C 001-003, 051-062,
A. If the test gives the maintenance message:
LOW OIL LEVEL:
- 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 below the ADD mark:
- do the oil servicing (Ref. AMM TASK 49-90-00-600-001).
- calculate the APU oil consumption.
(a) If the APU oil consumption is more than 65 cm3 (3.96 in.3) per APU operating hour:
- examine the APU externally for oil leaks on the oil system components or oil lines (Ref. AMM TASK 49-00-00-790-001).
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 leakage (Ref. AMM TASK 49-00-00-790-001).
- remove, clean and install the TURBINE BEARING CAVITY VENT (Ref. AMM TASK 49-91-53-000-001) and (Ref. AMM TASK 49-91-53-000-001).
a If the fault continues:
_
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-000-001).
(2) If the oil level is above the ADD mark:
- replace the OIL LEVEL SWITCH P8 (Ref. AMM TASK 49-93-16-000-001) and (Ref. AMM TASK 49-93-16-400-001).
(a) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/H2, H3, H4 to the OIL LEVEL SWITCH P8/3, 2, 1 (Ref. ASM 49-61/02).
(b) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001)R **ON A/C 063-099, 401-499,
A. If the test gives the maintenance message:
LOW OIL LEVEL:
with the LRU TROUBLE SHOOT DATA menu information:
OIL LEVEL SHOWS LOW
Fault Code Number: 099
- 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.
