I have had the MPV1 pro for at least 6 or 7 years now. I havn't used it in about a year and I pulled it out to access a computer and it wont let me in. It says interface can not be found. I have tried it on 3 vehicles and won't read. The busy light does flash slowly when plugged in. I can read my license info off the MPV1. Does this sound like a possible bad obd2 to serial cable? thoughts?
