__________________
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:
- the MCDU menu shows
NO LRU DETECTED
(4) Start the APU and apply Bleed Air for 20 seconds, minimum (Ref. AMM TASK 49-00-00-860-008).

A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO ACCELERATION
STARTERMOTOR (8KA)/APU ROTATION
associated with Fault Code Numbers (FCN) 212
- do a check of the aircraft BATTERIES (Ref. AMM TASK 24-38-00-210-001).
(1) If the fault continues:
- do a check for APU internal damage.
- do a check for contamination of the MAGNETIC-DRAIN PLUG (Ref. AMM TASK 49-91-42-200-004).
NOTE : If the MAGNETIC-DRAIN PLUG is not contaminated, continue
____
without starting the APU.
- .
- remove the end cap of the STARTER MOTOR (8KA).
- use a socket and a ratchet on the shaft of the STARTER MOTOR (8KA) to turn the APU counterclockwise (in the direction of the arrow on the housing). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 机载辅助动力 2(65)
