A. If the APU Last Leg Report gives the maintenance message:
OIL TEMP SNSR (8084KM) AND GENERATOR (8XS)
Fault Code Number: 122
Additionally:
Fault Code Number: 010 or 011 and 012 or 013
Subtask 49-00-00-710-233-B ** ON A/C NOT FOR ALL OIL TEMP SNSR (8084KM) AND GENERATOR (8XS)
Fault Code Number: 122
Additionally:
Fault Code Number: 010 or 011 and 012 or 013
NOTE: FCN 010-013 on Class 3 Faults Page
NOTE: The APU SHUTDOWNS report gives the maintenance message:
SENSOR FAILURE - OIL TEMP SNSR 8084KM AND GENERATOR 8XS
APU Auto Shut Down Fault Code Number: 122
SENSOR FAILURE - OIL TEMP SNSR 8084KM AND GENERATOR 8XS
APU Auto Shut Down Fault Code Number: 122
NOTE: Message does not appear in case of self-test of the ECB
- do check and repair the wiring from the ECB (59KD) AB/C2, D2 to the OIL TEMPERATURE SENSOR (8084KM) P25/1, 2 ASM 496102. ESPM 2052210 ESPM 2053210 ESPM 205321A.
The value must be: 106 Ohms at 15 degree C. (+/- 0.385 Ohms per degree C.). - do check and repair the wiring from the ECB (59KD) AB/C3, C4 to the APU GENERATOR (8XS) P4/3, 4 ASM 496102. ESPM 2052210 ESPM 2053210 ESPM 205321A.
The value must be: 96 Ohms at 15 degree C. (+/- 0.385 Ohms per degree C.)
- replace the SENSOR - TEMPERATURE, HIGH OIL [8084KM] AMM 49-91-51-000-002 and AMM 49-91-51-400-002.
- replace the GEN-APU [8XS] AMM 24-23-51-000-001 and AMM 24-23-51-400-001.
B. Do the test given in Para. 3.
