Chiekotz 7/9/2010Simply disconnect your battery, turn on the headlight switch for about five to ten minutes, and re-connect the battery. This is pretty simple, but will likely result in you losing your radio presets and perhaps some other small things like that.
Most if not all scan tools have an option to clear or reset codes without the use of any tools or touching the battery. Consult your tool's manual for information on how to do it with your particular model.
