3. Fault Confirmation
__________________
A. Check/Test
(1) Before you start the APU for the operational test, do the subsequent checks:
(a) Do a check and make sure that the cooling fan inlet duct, the oil cooler inlet duct and the oil cooler outlet duct are correctly attached and in the correct condition.
- correct/replace as necessary.

(b) Do a check and make sure that the LUBE-PUMP OIL FILTER and the GENERATOR OIL FILTER are not protruded.
(2) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-004).
NOTE : Operate the APU for min. 15 minutes under full load. This
____ makes sure that the oil temperature increases sufficiently.

A. If an APU shutdown occurs during the operational test of the APU and the test gives the maintenance message:
GENERATOR HIGH OIL TEMP - GEN SCAVENGE PUMP OR GENERATOR 8XS OR ECB 59KD:
- replace the GEN-APU (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001).
(1) If the fault continues:
- replace the GENERATOR SCAVENGE PUMP (Ref. AMM TASK 49-91-52-000-001) and (Ref. AMM TASK 49-91-52-400-001).
(2) 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).
(3) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C3, C4 to the APU GENERATOR (8XS) P4/3, 4 (Ref. ASM 49-61/02)
(4) If the fault continues:
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
