It appears my OBD connector has some sort of problem. Or maybe its deeper than the connector itself. Ive plugged my Rovacom lite into the OBD socket. The connector powers the unit but won't communicate. I thought maybe it was the laptop I purchased second hand. So I said let me try a different one. I have a hand held unit that I keep in my car. I plug it in, it powers up. Once I try to get it to read codes, it goes through whatever it does at start up. Then says there's an error or problem with the connection and won't communicate with the truck. As much as I want to pull the lower panel out where the connector is and rummage around looking for a frayed wire, I figured it would be best to post here to get a more knowledgable opinion from you guys before I do more harm than good. Thanks in advance for any and all replies.
