the only way to remove the tune would be to overwrite it with another tune or you have a pcm failure. You can have the battery out for years and it wont matter, it's not in the temporary memory.
the tune file should stay on the device unless someone deletes it (which on every tuner I've seen would require it to be connected to a laptop).
if the light on the traction control button is always off and won't turn on this is a hardware issue imho. Wiring, button, fuse etc...
