Hi all! My CX-5's Obd2 port is not responsive after recent battery change. I believe I must have blown then Obd2 fuse. Does anyone know what fuse or fuse number it is? Thanks!
I saw this but all I know is that the obdii is a data port. I have never read it supplies DC, like usb. So I wonder if the data lines are fused. It would be unusual.
Hey, I have the same issue now. Was there ever a diagnosis?
Turned the power on?Obvious thing first, have you turned the power on (the CX-5)?
The OBD connector has power to it even with the ignition off, if this is what you are referring to.Obvious thing first, have you turned the power on (the CX-5)?
The OBD connector does not have power with the ignition off.The OBD connector has power to it even with the ignition off, if this is what you are referring to.
If there is no power then why does my obd2 scan tool turn on when I plug it in without ever pushing the start button. It doesn't have batteries.I've replaced countless batteries in Mazdas, I'd say over 300. I've never experienced something like that. You can try clearing the KAM (disconnect negative battery terminal and hold the brake pedal down for at least 30+ seconds) and reconnecting. Trying using your scan tool again. Make sure it's KOEO and it SHOULD work.

I'm not aware of a fuse specific to the OBD. I can look into further tomorrow at work, hope this helps though!

For some reason my Scangauge ( which is plugged into the obdii port )lights up when I plug in a battery charger.Exactly what Jmaz said. There has to be power to the OBD connector. I have two OBD devices and they both power up as soon as they are plugged into the OBD connector while the car is turned off.
@thispart, you're mistaken.
