OBDII Port not working

[WTFJ80]

Hey guys, I am having some issues with my OBDII port not working on my 2010 Nissan Altima. I have had a sale fall through because the scanner couldn't communicate with the car to let them know that there were no issues... now it seems as though there is one.

I already checked the fuses and they all seem to be in perfect working order.

Not sure what else I can do right now. Anyone have an idea of what might be wrong with it?

Thanks!

Check for continuity and ground at the plug

Are you using a cable, or a blue-tooth dongle? My 4Runner is finicky, and I've had the fuse blow. Try replacing the fuse anyway, or swapping with another known-good one.

I could probably help you, i hacked vehicle CAN ports for a living a while back lol. PM me and i can walk you through what to check

^ This. Mine didn't work in our 100. For some reason the fuse didn't "look" bad. Replaced and worked.

Another help if you need it.

I also do ecu programmingand know those systems very well.

I also know a few Nissan software engineers.
So pm me if you get stuck.

Carbon, do you work at the nissan proving grounds in copa? I used to test there. Bruce let me have free access to a GTR to drive around the track - super fun!

NTC is my favorite of the 20 or so proving grounds I visit each year. Second favorite is HPCC. Only because I'm the only guy testing out there.

NTC is 78miles each way from the house. Makes for really long days.
AGP is 8 miles. Toyota is 15
I have seen Bruce in a year. He renewed me last time I needed it.

The GTR is a hoot. But Superbike testing on the oval is a lot more fun. You can see the ground go by at your feet.

Sweet! I have tested at Nissan, Volvo/Ford, Old Chrysler (whitmann, across from the ford/volvo proving grounds) and are setup to test at the GM proving grounds in Yuma and NATC up in Nevada. The only proving ground that i have had trouble getting into was VW.

If you go to yuma. Watch for the rail gun across the highway.

I'm sure we have crossed paths at some point.
