If you are talking about the SES light, you need a code reader to turn it off.

5. Replace fuses
6. Start the car and the make sure the light has went off

This worked for me. The only thing is, mine didn't say "PCM BAT or PCM IGN", it was something like PCM B and PCM 1 or PCM I or something of that nature.

Ohh, didnt know about that one. Do now!

Also, unless you know what the code is/was and if it was fixed, turning off the light/reseting the computer will erase all of the past codes. Just suggesting you get it fixed, unless you have already done/had it done.
