- do a check of the oil level in the APU oil reservoir:
(1) If the oil level in the APU oil reservoir is not sufficient:
- do the oil servicing (Ref. AMM TASK 49-90-00-600-004) and replace the OIL PRESSURE SWITCH (8091KM) (Ref. AMM TASK 49-94-14-000-002) and (Ref. AMM TASK 49-94-14-400-002).
(a) If the FCN 043 continues:
- do check and repair the wiring from the ECB (59KD) AB/C5, J4 to the OIL PRESSURE SWITCH (8091KM) P14/1, 2 (Ref. ASM 49-61/02).
1 If the FCN 043 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. Oil Level Check and Test
(1) Do a check of the oil level in the APU oil reservoir and do the oil servicing if you find that the oil level is not sufficient (Ref. AMM TASK 49-90-00-600-004).
(2) Do the self-test of the ECB (59KD) (Ref. AMM TASK 49-00-00-710-005).
4. Fault Isolation
_______________
A. If the test gives the maintenance message:
OIL PRESS SW (8091KM) AND OIL LEVEL SNSR (8089KM)
Fault Code Number: 140
Additionally:
Fault Code Number: 43 and 50
or
Fault Code Number: 43 and 49
NOTE : The APU SHUTDOWNS report gives the maintenance message:
____ SENSOR FAILURE - OIL PRESS SW (8091KM) AND OIL LEVEL SNSR (8089KM) APU Auto Shut Down Fault Code Number: 140
NOTE : Message does not appear in case of self-test of the ECB
____
- replace the OIL LEVEL SENSOR (8089KM) (Ref. AMM TASK 49-93-17-000-001) and (Ref. AMM TASK 49-93-17-400-001).
- replace the OIL PRESSURE SWITCH (8091KM) (Ref. AMM TASK 49-94-14-000-002) and (Ref. AMM TASK 49-94-14-400-002).
(1) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C5, J4 to the OIL PRESSURE SWITCH (8091KM) P14/1, 2 (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/H2, J4 to the OIL LEVEL SENSOR (8089KM) P8/1, 2 (Ref. ASM 49-61/02).
(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.
