    What is an OBD-II connector and does my car have one

    Please note, an OBD-II scanner is not required for the TripLog solution.

    On-board diagnostics (OBD) is an automotive term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems, for example, check engine light.

    OBD-II compliant vehicles.

    • Please note that TripLog requires your vehicle to support a very specific code: OBD PID 31 “Distance traveled since codes cleared”. Vehicles that are OBD-II compliant may or may not support this code and it is hard to predict which vehicles will support this code simply based on their makes and models. Please consult your vehicle’s owner’s manual and other information available online to see if your vehicle supports this code.
    *The vehicle names may differ from the actual vehicle but should serve as a reference for successful pairing.

    What is an OBD-II scan tool and where can I buy one?

    An OBD-II scan tool is a small device that plugs in to the OBD connector and transfers data via Bluetooth to mobile devices.

    You can find many choices on the web. Make sure it has the ELM327 interface and is proven to work with other Android apps, like Torque.

    We’ve tested:


    ScanTool OBDLink LX

    ScanTool OBDLink MX
    for Ford and GM

    How does TripLog for Android work with the OBD-II scan tool (optional)?

    1. Plug the OBD-II scan tool in to the OBD connector, and start the engine.
    2. Go to Android System Settings > Bluetooth > Search for devices > Pair with it (the security code usually is 1234 or 12345, check the device manual).
    3. Open TripLog Android app > menu > Settings > OBD-II Device Settings > OBD-II Scanner Type > Bluetooth. OBD-II Bluetooth Device > select the newly paired device.
    4. On the same settings page > Setup Vehicle Odometer > Yes > app will try to connect to the scan tool, once it finds it > select the vehicle > enter the current odometer from dashboard. If it fails to connect, read the popup message and try again.
    5. Start a trip as usual. The app will automatically read odometer from the scan tool.
    • Due to the fact that OBD devices only give distance in kilometers, if you use miles, there might be some loss of precision and resulting in readings being 1 mile off.
