ATCMacro Meldas 500 HELP!

I have a problem with the ATC device. In my DYNA MYTE 4800, the ATC doesn't move when I put a function on MDI mode for the tool change.
First time I think it was the syntax of the function, I tried whit M06 T10 instead of T10 M6, and the outcome still the same 'P290 IF SNT. ERROR'. When I looked in Mitsubishi manual for that failure code it said that I need to 'Check the code'.
I keep searching and I found a procedure to 'remove the edit program lock (A) (B) and (C)' but not sure if this will help. At this point, I don't know what else to do.
What I think, is that I need to re-program the ATC macro (don't know where exactly to do this)for the 09001 ATC-MACRO NEW, which is this:
M66;
M09;
G4P1
IF[#1005 EQ 1] GOTO 9;
G28 Z0. M19;
M32;
G4 P100;
N5 G30 Z0 P2;
G4 P100;
M33;
G4 P200;
N8 G28 Z0;
G4 P10;
M34;
M35;
N9 M67;
M99;

Well, that's the best I can do for the moment...I'm stuck.
Thanks!
