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, the check engine light. An OBD-II scanner is NOT required for mLog.

Please note that mLog 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.

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.
