You'll Need Diagnostic code scanner.
Visit a car retailer and shop for an OBD code scanner. The more you pay the more functions the scanner will have. Some higher end diagnostic tools are multilingual or can diagnose several systems. Cheaper tools are dedicated only to OBD2 codes. Also, the scanner you selected to purchase will also rely on which trouble indicator light is come on your car. You will have a regular 'Check Engine' light, as well as a separate light for brakes, airbags, and tires. If your airbag light is active, you should drive your car to a mechanic; diagnostic tools are not as widely available, and the needed repairs are more complex.
Connect the diagnostic scanner to the computer outlet on the driver's side of the car. For most cars, this outlet is under the dash, somewhere between the gas pedal on the right and the hood release on the left. It is often black in color, and will feature 16 or 20 pin receptors. The plug at the end of the scanner's cable should easily fit, so do not jam it in.
Power the scanner on. You should do this for some diagnostic tools, but not for others. Some scanners will turn on by themselves once a link with a car's diagnostic system is sensed. The process might differ slightly by brand and diagnostic system, but the process is basically the same.
Plug your key into the car's ignition and turn to the 'On' or 'Run' position. This also may vary referring to car model, so look up your manual often.
Wait a moment while the diagnostic system and the scanner establish a connection. You will know the two systems are linked once an error code appears on your scanner screen.
Reference the error code with the scanner's service manual. The manual will have a list of error codes and definitions. If you are using an OBD2 scanner, these error codes will be generic ones approved by the Society of Automotive Engineers. Manufacturer specific codes will probably not be in either the scanner or the owner manual. Write the code down on a piece of paper if this is the case, and consult it online. There are lots of websites online devoted to error codes and their translations. Please come to our website, lots of product of OBD, and lots of information.
