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).

 (2) If the APU Last Leg Report gives the maintenance message:
 INLET T-P SNSR (8013KM): Fault Code Number: 008 or 009
 - replace the INLET T-P SENSOR (8013KM) (Ref. AMM TASK 49-23-17-000-001) and (Ref. AMM TASK 49-23-17-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring (Temperature Side of the Sensor) from the ECB (59KD) D3, E6 to the INLET T-P SENSOR P22/ 6, 5 (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.

 3. Fault Confirmation__________________
 A. Test
 (1) Do the operational test of the APU fuel low pressure warning (Ref. AMM TASK 49-31-00-710-002).

 (2) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-008).

 4. Fault Isolation
_______________

 A. If the APU Last Leg Report gives the maintenance message:
 FUEL LOW PRESS / LOW FUEL PRESS SW (5030QM): Fault Code Number: 112
 - do the operational test of the APU fuel pump-system (Ref. AMM TASK 28-22-00-710-001) and make sure that no air is in the APU fuel line.
 (1) If the fault continues:
 - replace the APU FUEL LP-SWITCH (5030QM) (Ref. AMM TASK 28-22-14-000-001) and (Ref. AMM TASK 28-22-14-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring from the ECB 59KD AB/B7, B8 to the APU FUEL LP-SWITCH (5030QM) P17/1, 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. If the operational test of the APU fuel low pressure warning gives that the FUEL LO PR advisory is abnormally on:
 - do the trouble shooting of the APU fuel low pressure (Ref. TASK 28-22-00-810-801).
 C. Do the test given in para. 3.
