A. Read-out of ECB Trouble-Shooting Data
(1) Put the APU MASTER SW to the ON position.
(2) Get access to the APU SHUTDOWN report.
(3) Push the '>' adjacent to LRU DATA:

A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO ACCELERATION
OIL TEMP SENSOR P11
associated with the Fault Code Number (FCN) 55
- do a check for damage/contamination of the electrical connector P11 of the OIL TEMP SENSOR (P11)
(1) If the electrical connector P11 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector P11 is OK:
- use a multimeter to do a resistance check across pin A and pin B of the OIL TEMP SENSOR (P11).
(a) If the resistance value is > 200 Ohms:
- replace the OIL TEMP SENSOR (P11) (Ref. AMM TASK 49-94-15-000-001) and (Ref. AMM TASK 49-94-15-400-001).
(b) If the resistance value is in the specified limit:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J5,B8 to the OIL TEMP SENSOR (P11) P11/A,B (Ref. ASM 49-61/01).
