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 SHUTDOWN report.
(3) Push the '>' adjacent to LRU DATA:
- the MCDU menu shows
NO LRU FAULT DETECTED
(4) Start the APU and apply Bleed Air for 20 seconds, minimum (Ref. AMM TASK 49-00-00-860-008).

R **ON A/C 001-049, 101-105, 107-107, 151-154, 201-207,
A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
HIGH OIL TEMPERATURE
OIL COOLER/COOLING FAN ASSEMBLY
associated with the Fault Code Number (FCN) 211
- do a check for
blockage of the air intake duct
blockage of the APU inlet housing
OIL COOLER ducting for blockage or contamination.
(1) If there is no blockage or contamination:
- replace the OIL TEMPERATURE SENSOR (Ref. AMM TASK 49-94-15-000-001) and (Ref. AMM TASK 49-94-15-400-001).
(a) If the fault continues:
- do a replacement of the OIL COOLER (Ref. AMM TASK 49-91-44-000-004) and (Ref. AMM TASK 49-91-44-400-004).
(b) If the fault continues:
- replace the COOLING-FAN ASSEMBLY (Ref. AMM TASK 49-52-51-000-002) and (Ref. AMM TASK 49-52-51-400-002).
(c) If the fault continues:
- replace the APU GENERATOR (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001).
