someone suggested doin this: You can reset the computer by disconnecting both battery cables and touching the disconnected cables together for a couple seconds. Reconnect everything and fire it up. You may have to give it some gas (pedal) to get it started, and it may idle erratically for a bit, as the computer may have to re-learn the various sensor parameters.[/QUOTE]

I Don't know any better but couldn't this harm the computer using this method don't want to screw the computer up just to get a lite on the dash to go out I seriously do not know anything on this so a little timid I guess???:???:

That method is safe however, wait at least 5 mins before you short out the positive to the negative cables after disconnecting them from the battery. remember, the air bag system has a capacitor that needs to discharge at a normal rate. If the cables are shorted prior to it's normal discharge, it may damage the airbag controller module.
