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 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:
OVERSPEED
FUEL CONTROL UNIT P19 / ECB (59KD)
associated with the Fault Code Number (FCN) 201
- replace the FUEL CONTROL UNIT (P19) (Ref. AMM TASK 49-32-11-000-003) and (Ref. AMM TASK 49-32-11-400-003).
(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).
