How do you disable the check engine light on a Subaru Forester?

I too know the frustration of Subaru check engine lights. The quick way is either black tape over the light on the dash or remove the bulb. Keep in mind that although you may know the code and the problem (both of mine routinely issue P0420 for a catalytic converter even though I've replaced same more than once) there may be additional problems crop up and you will get no additional warning. --Ken
