B. Safety Precautions
(1) On the center pedestal, on ENG panel 115VU:
(a) Make sure that the ENG/MODE selector switch is in the NORM position.
(b) Make sure that the ENG/MASTER 1(2) control switch was in the OFF position not less than five minutes before you do this procedure.
(c) Put WARNING NOTICE(S) in position to tell persons not to operate:

The ENG/MODE selector switch, and
The ENG/MASTER 1(2) control switch.

(2) On the ENG section of maintenance panel 50VU:
(a) Make sure that the ON legend of the FADEC GND PWR/1(2) pushbutton switch is off.
(b) Put a WARNING NOTICE(S) in position to tell persons not to energize FADEC 1(2).

Subtask 73-29-00-860-100-A

D. Aircraft Maintenance Configuration
(1) On the ENG section of maintenance panel 50VU:

Release the FADEC GND PWR 1(2) pushbutton switch (the ON legend comes on).

(2) After the FADEC is energized, wait a minimum of 60 seconds before you start the test. If you do not wait 60 seconds, the interactive mode stops the EEC self-test which can cause unwanted faults and the OMAP software part number (SW2) will not be displayed.
(3) On the left or right Multipurpose Control and Display Unit (MCDU), get the SYSTEM REPORT/TEST/ENG page (Ref. AMM TASK 31-32-00-860-012).
(4) Make sure that the landing gear system is not simulated in the flight configuration (Ref. AMM TASK 32-69-00-860-001).

4. Procedure
