C. Aircraft Maintenance Configuration
(1) On the center pedestal, on the ENG panel 115VU, make sure that the ENG/MASTER 1 and ENG/MASTER 2 control switches are at OFF.
(2) On the overhead panel, on the maintenance panel 50VU, release the ENG/FADEC GND PWR/1 and 2 pushbutton switches (the ON legend of these pushbutton switches comes on).

A. GROUND SCANNING test of the DMC1 (2 or 3)
5. Close-upNOTE: This test is for the DMC1. For the DMC2 and DMC3, use the indication between parentheses.
| ACTION | RESULT |
|---|---|
| 1. On the MCDU: - press the line key adjacent to the EIS1 (2 or 3) indication | - the DMC1 (2 or 3) main menu page comes into view - a green MAINTENANCE MODE message comes into view on the CAPT PFD, ND, EWD SD (F/O PFD and ND with the DMC2), (no cockpit effect with the DMC3) |
| - press the line key adjacent to the GROUND SCANNING indication | - the NO FAULT DETECTED indication comes into view |
| - wait for 15s to confirm that no trouble shooting data has occured | - make sure that the message NO FAULT DETECTED is still displayed |
| - push the line key adjacent to the RETURN indication. | |
