View Full Version : Obd2 Port not working!

05-06-2013, 05:01 AM
I have a 2009 JKU and my OBD 2 port isn't working when I plug something in. I took a test light to it and there is no power and can't find a fuse for it. Any advice???

Wow, never heard of that before. There should be no fuse to it as it goes right to your computer. I might just make sure there aren't any loose wires coming out of it.

I work for a GPS company and we have devices that plug into the OBDII port on vehicles. In troubleshooting these during installation we have found that some individuals do not have power to the OBDII port. In several manufacturers I have found the OBDII's power to run through the same fuse as the cigarette lighter (mainly in Ford). I would check your fuses again, but like Eddie said haven't heard of this happening in the Jeep before, nor do I know if or what fuse it is linked to specifically.

I'll ask the obvious - you have the jeep on?

I've tried it with it off, in acc, in ignition poison and running.

while checking all connections also check your grounds - did you add any electrical extras?
