I think that my check engine light port is not working and that my light is not working either. I mean I do not think the light comes on even though there is a problem that should make the light come on. Can u tell me how to find out if my port has power and how to know if my obd2 is working? There are several electrical problems that my car has had for a while like the radio going back and forth from radio to cd just out of nowhere and the high mounted break light(the third brake light)not working. Also a while back someone riged a cable from my fuse box under the hood to my fuse box under my dashboard, and that made the port start working, but the cable fell off and I do not know which fuse it came from and which one it went to in order to try to re-right. So, I need help to check if my obd2 system is working and to fix it if it is not. And the radio and third brake light too but the obd2 is first priority.
