Config-2 Aug 01/05 CES (1) If the fault continues:
- replace the FUEL CONTROL UNIT (8022KM) (Ref. AMM TASK 49-32-11-000-002) and (Ref. AMM TASK 49-32-11-400-002).
(a) 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.

A. Do a visual check on the oil sight glass on the accessory drive gearbox:
- do the oil servicing (Ref. AMM TASK 49-90-00-600-004).
- calculate the APU oil consumption.
4. Fault Isolation
_______________
(Ref. Fig. 201/TASK 49-00-00-991-003)
A. If the APU oil consumption is higher than the GRAPH A on Fig. 001:
- examine the APU externally for oil leaks on oil system components and oil lines (Ref. AMM TASK 49-00-00-790-002).
(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 49-00-00-790-002).
(a) If the fault continues:
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-003) and (Ref. AMM TASK 49-11-11-000-003).
B. Do the test given in para. 3.
