  1. Install the ELM327 OBD2 software package of your choice.
    • For ease of use we suggest the ScanMaster-ELM Demo or EasyOBD-II
  2. Connect the ELM Interface to your computer and allow the drivers to automatically install.
    • Make sure your computer is connected to the internet and your computer is allowed to download new drivers.
    • If the drivers fail to install, attempt to install the drivers manually.
  3. Identify the COM-Port associated to the device in the Device Manager.
    • Consider opening the device manager before you plug in the OBD-II adapter so you can see the item added to the device list in real-time.
  4. Start your vehicle or have the ignition switch on with power to the battery.
  5. Connect your ELM327 Interface to the OBD-II adapter in your vehicle.
    • The OBDII plug is normally located under the steering column; No tools are required to locate it. If you are having trouble, keep in mind that it is no further than 3 feet away from the driver.
  6. Open the OBD-II software and connect to the interface by selecting the COM-Port associated to the device.
    • If the COM-Port is set higher than the software allows, you will need to change the COM-Port in the Device Manager by right clicking on properties. More information about this is provided in our Comprehensive ELM327 Guide.
    • If the software fails to connect to the interface, un-install it from the Device Manger and reinstall the drivers by plugging in back in.
  7. Go online and connect to the vehicles ECU. Trouble codes and real-time data should now be available to you.
