Most common code to show up with a tuner. It will also show up if you have unplugged the batteries. Stands for KEEP ALIVE MEMORY. No big deal, mine shows it all the time. Clear the code with the SCMT and it should go away. It will not hurt anything though.

(At least that's what mine did back when I had my SCMT... Forget about that code and drive!!
