A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO ACCELERATION
DEOIL SOLENOID P15
associated with the Fault Code Number (FCN) 133
- do a check for damage/contamination of the electrical connector P15 of the DE-OIL SOLENOID VALVE (P15)
(1) If the electrical connector P15 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector P15 is OK:
- use a multimeter to do a resistance check across the pin 1 to the pin 2 of the DE-OIL SOLENOID VALVE (P15)
(a) If the resistance value is > 80 Ohms:
- replace the DE-OIL SOLENOID VALVE (P15) (Ref. AMM TASK 49-91-49-000-003) and (Ref. AMM TASK 49-91-49-400-003).
(b) If the resistance value is in the specified limit:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J4 to the DE-OIL SOLENOID (P15) P15/1 and the DE-OIL SOLENOID (P15) P15/2 to GND (Ref. ASM 49-61/01).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
B. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO ACCELERATION

- do a check for damage/contamination of the electrical connector P15 of the DE-OIL SOLENOID VALVE (P15)
(1) If the electrical connector P15 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector P15 is OK:
- use a multimeter to do a resistance check across pin 1 and pin 2; required value > 10 Ohms and pin 1 and pin 3; required value > 100 kOhms of the DE-OIL SOLENOID VALVE (P15)
(a) If the resistance values are out of the specified limits:
- replace the DE-OIL SOLENOID VALVE (P15) (Ref. AMM TASK 49-91-49-000-003) and (Ref. AMM TASK 49-91-49-400-003).
(b) If the resistance values are in the specified limits:
- use a multimeter to do a resistance check across pin 2 and pin 3; required value > 10 Ohms and pin 2 and pin 15; required value > 100 kOhms of the DATA MEMORY MODULE (P20)
1_ If the resistance values are out of the specified limits:
- replace the DATA MEMORY MODULE (P20) (Ref. AMM TASK 49-73-
32-000-001) and (Ref. AMM TASK 49-73-32-400-001).
2 If the resistance values are in the specified limits:
_
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J4 to the DE-OIL SOLENOID (P15) P15/1 and the DE-OIL SOLENOID (P15) P15/2 to GND and the ECB (59KD) AB/J4 to the DATA MEMORY MODULE (P20) P20/2 and the DATA MEMORY MODULE (P20) P20/2 to GND (Ref. ASM 49-61/01).
a If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
