Go to the tech section, its under ECU reset. Very easy to do, make sure you read the whole post.

just unplug your battery terminal and leave it unplugged for about a minute. plug it back in and you should be good to go

 

Go to the Tech Section, Mike (Mikochu) shows you how to reset w/o unplugging the negative terminal, and by pulling a specific fuse.
