Disklavier

I second Carol's wise advice.  Perhaps you know the old proverb, "Fools 
go where angels fear to tread."  Unless you know what you are doing, you 
are well-advised to stay out of the Test and Maintenance modes.  They 
are there for qualified Yamaha-trained technicians.  However, I believe 
that anyone who owns a Disklavier, has every right to risk screwing it 
up and to pay someone to undo his folly.

That said, and at your own risk, you enter the Test Mode with the 
"Power" switch off.  You then hold down the "L" and "R" buttons while 
depressing the "Power" switch to "ON".  The LCD will indicate that you 
have reached the "Test Mode" and will indicate that the "+" and "-" 
buttons will scroll through the menu of available tests.  The ">> (Song 
Select)" button will scroll through sub-menus and "Play/Pause will 
activate a test.  Shut the "Power" switch off to leave the Test Mode.

You enter the Maintenance Mode with the "Power" switch off.  You then 
hold down the "<<" and ">>" (Song Select) buttons while  depressing the 
"Power" switch to "ON".  The LCD will indicate that you have reached the 
"Maintenance Mode".  Press "R" or "L" to scroll through the menu of 
available procedures.  The "Play/Pause" button will activate a 
procedure.  Shut the "Power" switch off to leave the Maintenance Mode.

I've said too much.  Don't ask me for further details.

BTW, your Disklavier surely must have a Maintenance Mode--otherwise, I 
don't know how anyone could do the calibrations for keyboard and pedal 
playback.
