12 Battery input to PCM disconnected during last 50 key starts. Check and test the battery feed circuit pin no.3 on the computer

12 just means the ignition switch was turned off. It's only a problem if it comes back during a test drive and you read the codes before turning the ignition switch off. Every car has this code but some models don't bother to display it.

(Hi rasmataz. Happy Thursay!)
