    My Bully Dog BDX Tuner Does Not Power up While Connected to my Vehicle. It Does, however, Power on While Connected to my PC.

    February 4th, 2021

    Why does my Bully Dog BDX Tuner not power up when connected to my vehicle?

    1. Have you tried connecting the device to a different vehicle? This can be a quick way to determine if this could be a device or vehicle issue.
    2. If you do not have access to another vehicle then you can check your vehicle fuses that power your OBDII port. (This varies by vehicle, please check vehicle's owners manual)


    If the device fails to power up at multiple vehicles and/or you can confirm that your OBDII port has power, we will need to do some live troubleshooting.
