Is it safe to use OBD port for dash cam?
No, that’s bad because it blocks off the OBD2 port and the wire could get knocked out. You could splice in behind the port if you know which wire is switched 12V though.
Is the OBDII diagnostic port on a Ford Expedition working?
However as it turns out Ford decided not to support the standard ISO 9141-2 and ISO 14230-4 signals nor did they support SAE J1850 PWM for engine and vehicle diagnostics. Instead they moved forward with using CAN bus signals (ISO 15765-4 and SAE-J2284) communications for OBD II diagnostics.
What is the location of the OBD port?
The OBD Port, is the location where you can plug in any OBD tool into the vehicle to pull vehicle information. It is also the primary location of tracking devices such as dongles as the port provides ongoing power to the device. There are two generations of OBD ports, OBD1 and OBD-ii aka OBD2.
Why is the diagnostic port on my OBDII not working?
I checked the fuse, as some have said this can be the culprit, however having power there left me skeptical, but yes the fuse was fine as I had expected it to be. Wiring going to the port looks good. I’m going to disconnect the battery and let it sit for a while and then hook it up and try again, but other then that I have no ideas.
What is the ISO pin on a Ford Expedition?

What’s the fuse for the OBDII diagnostic port?
Another very helpful thread. Went to scan the truck after replacing the fuse box, plugged in the scanner and nothing… Saw this thread and threw my USB dongle in the power outlet and presto, no light. Checked fuse 41 (2003 EB 5.4), a 20A fuse.
What to do if your OBD port is not working?
Both the OBD port and cig lighter share the same fuse. Or, just try swapping a new fuse in there. I have heard of times where a fuse that “looks” fine turns out to be faulty. If it isn’t that, then I’d say it’s probably time to start backtracing and seeing if you have a broken wire somewhere. Does your cigarette lighter/port have power?
Only the K line ISO pin is connected and not the L line ISO pin. The only thing connected to the K line ISO pin is the Restraint Control Module and the Parking Aid Module again not the PCM.
