HOW TO – Read your car’s mind OBDII

Scantool1Drew writes “If your vehicle was manufactured after 1996, it contains an On Board Diagnostic (OBD) computer that captures information about how it’s running. I’ve put together a basic HOWTO Guide for OBD-II so that you can get started playing with it. I use ScanTool‘s great hardware and GPL’d software for my setup. You can use it to save money by reading error codes without a trip to the mechanic when your “check engine” light is on, capture performance data about your car’s drivetrain in real-time, or log data as if it were an airplane’s “black box”.” Link.
