2004 XC90 OBD II port stopped working

Hi all,

The OBD II port on my 2004 XC90 stopped working properly. While I probably wouldn't care so much normally, I use a Metromile tracker (auto insurance priced per mile), and without a signal, they'll charge me as if I'm driving 150 miles per day.

I checked the interior fuses and tried a Wi-Fi OBDII reader that also doesn't connect properly.

Is there anything else I should be looking for?

Any help would be greatly appreciated.

cheers,
Bruno

Check fuse #22 in the panel at the left side of the dashboard. Refer to page 145 (Maintenance) in this https://volvo.custhelp.com/app/manuals/ ... /om_id/635 manual.

Thanks, wanderüne. I've gone through fuse 22, as well as every fuse under the hood, in the cabin, and in the trunk. Everything checks out, but I'm still not getting a steady connection. (It did connect properly once with ignition in 'on' position but engine off.)

Also, strangely, the moonroof stopped working. That fuse also looks OK. Any ideas would be welcome!
