The map command works only in command mode, after you have typed the colon :

If your current map command worked from text input mode you would be typing text and all of a sudden the program would quit. Bad choice, if it worked.

To debug your .exrc file try starting ex because the error message from .exrc errors is only visible for a very short time. q! quits ex.

ab works only in text-input mode when the abbreviation or keystroke map you created is typed standalone - it has to be a word all by itself - no characters except space, tab, or return.

So your ab is okay, just a learning curve issue. Do not create an abbreviation of simple text that will take you out of text mode and do a force quit.
