3. Fault Confirmation
__________________
A. Read-out of ECB Trouble Shooting Data
(1) Put the APU MASTER SW to the ON position.
(2) Get access to the APU LAST LEG/PREVIOUS LEG report.
(3) Push the '>' adjacent to the related CFDS failure message:
- the MCDU menu shows:
OIL FILTER SWITCH SHOWS ELECTRICAL GROUND
- do the Fault Confirmation that follows:
(a) Start the APU (Ref. AMM TASK 49-00-00-860-008).
(b) Get access to the APU GND SCANNING menu.
(c) Shut down the APU (Ref. AMM TASK 49-00-00-860-009).

A. If the APU GND SCANNING menu gives the maintenance message:
LUBE PUMP FILTER SW P9 / GEN SCAV FILTER SW P5
associated with Fault Code Number (FCN) 101
- do a check for damage/contamination of the electrical connector P9 and P5 of the LUBE PUMP FILTER / GENERATOR SCAV FILTER.
(1) If the electrical connector P9 and/or P5 is damaged, do a repair. If it is
- contaminated, clean it.
(2) If the electrical connector are servicable. 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(171)
