How many seconds should battery be disconnected to reset computer?

It depends on the vehicle. You'll need to refer to the owners manual for specifics. Most vehicle manufacturers don't require that you disconnect the batery any more. Why would you want to reset all of the radio buttons every time you change the oil? On the other hand, if you're talking about resetting an error condition, many of the OBD code scanners can send a reset pulse to the computer, and you don't even need to unplug anything... except the OBD code scanner when you're finished. I just noticed that this is a Caddilac question, many GM vehicles have an "Oil Service" reset button under the hood, in the fuse panel that is adjacent to the battery. With the keyswitch ON but the engine not running, press and hold the button for about 10 seconds. If someone is watching the dashoard they should probably see the oil light flash a couple times. When you're done, turn the key off. Next time you start the engine, the oil change light should act normal again (bulb test when you first turn on the key). 5 minutes.

If code 12 means the battery or computer has been disconnected how do you reconnect the computer?
Can you be more specific? Was your battery disconnected or did it lose it's charge? If you did not disconnect the computer, it would not need to be reconnected. If your battery was dead or disconnected, simply remove the positive battery cable for about 10 minutes and re-connect it. This should clear your code. Even if the code does not clear you should have no problems with the function of your car.
