This is the security code for theft radio system; add it; the radio code generaly is in back side of the radio, or in the owners manual (last page). If you dont have anyone, need to call the Acura dealer with the VIN car number (sometimes need to pay for this service).
Hope helped (remember coment and rated this post).

Has anyone found the problem? My 2003 has #3 cyclinder misfire and I have replaced the plugs and wires. It runs rough at idle but smooths out at highway speed. Anyone have any knowledge on this? This sounds like a common problem.
P0303 is a misfire in cylider 3. This is almost always an ignition coil in this car. I would swap out all 8 with Motorcraft coils as well as spark plugs. If one is going, the others arent far behind and one bad one makes the others work harder.
