(1) If there is a ground signal and 115VAC:
- replace the OIL HEATER (8093KM) (Ref. AMM TASK 49-96-51-000-001) and (Ref. AMM TASK 49-96-51-400-001).
(a) 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).
(2) If there is no ground signal:
- do a check and repair the wiring from the APU OIL HEATER (2KT) P6/2 to the ground (Ref. ASM 49-96/01).
(3) If there is no 115VAC power supply.
- replace the APU AUX CTL RELAY (32KD) (Ref. ASM 49-96/01).
(a) If the fault continues:
- do a check and repair the wiring from the APU OIL HEATER (2KT) P6/1 to the SERVICE BUS 2 (214XP-B) (Ref. ASM 49-96/01).

3. Fault Confirmation
__________________
A. Do a read out of the APU SHUTDOWNS report.
4. Fault Isolation
_______________ **ON A/C 001-003, 051-062,
A. If the APU SHUTDOWNS report gives the the maintenance message:
LOW OIL PRESSURE - LOW OIL LEVEL:
- do a check of the oil level.
(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 49-91-53-400-001).
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).
R **ON A/C 063-099, 401-499,
A. If the APU SHUTDOWNS report gives the the maintenance message:
LOW OIL PRESSURE - LOW OIL LEVEL:
with the LRU TROUBLE SHOOT DATA menu information
OIL LEVEL SHOWS LOW
Fault Code Number: 099
- do a check of the oil level.
(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).
