FAQ:
Q: What does OBD2 stand for in car software?
A: What is OBD2 software? OBD stands for “onboard diagnostics,” and is a protocol included in all modern vehicles. OBD2 software lets you access and interprets this data. Just connect your device to your car with an adapter, and you’ll get dealer-level access to emission data, sensor readings, and diagnostic trouble codes.
Q: Which is the best OBD2 software for Mac?
A: Car Scanner ELM OBD2 is the best OBD2 software for Mac and Android users, though it lacks access to some of the PIDs offered by other options. On the affordable end of the spectrum, EasyOBDII Premium Software provides in-depth OBD diagnostics at a price of just over twenty bucks.
Q: How can I send data to an OBD-II adapter?
A: OBD-II will never send data on it’s own, it listens for a command you send and based on that command it will send an answer. So basically you have to do two things if you have a running connection: Send the correct commands to the OBD-II device.
Q: Is there free do it yourself OBD software?
A: OBD-2 do-it-yourself diagnostics puts owner in equal position to mechanic. However malfunctions or broken parts should still be repaired and not just dismissed with a simple “Clear fault” button within the Windows/Mac software. These are not free OBD software.
