Oct. 24, 2012 - PRLog -- How to Diagnose Car Problems With an OBD2 Onboard diagnostics, or OBD, is an electronic system that allows an auto technician or car owner to see the health of a car. The OBD was first introduced in the early 1980s and the OBD2 is the improved version of the original program. OBD2 first alerts the driver of a problem in the car by the use of the "Check Engine" light on the dashboard console.  Start the ignition and watch the components on the dashboard console. The light for "Check Engine" or "Service Engine Soon" should flash briefly. This indicates that the OBD2 is present and ready to diagnose problems that may exist. 2. Check the dashboard console as you drive. If there are any problems, the "Check Engine" or "Service Engine Soon" light will come on and stay on. The OBD2 will alert you to problems ranging from a loose or missing gas cap to an engine misfire. 3. Look for blinking lights on your dashboard console. Blinking lights indicate that there is a serious problem occurring with the engine of the vehicle. It will be safer to limit your driving until this problem has been resolved. 4. Use a personal OBD2 code reader to scan for problems (see Resources below). Attach the reader to your car's 16-pin port, which is usually located under the steering wheel. The reader will display the problem codes generated by your car's computer, as well as the definition of the codes. 5. Take your car to an auto technician if you are unable to discover the source of the problem on your own. The auto technician will use a professional OBD2 reader for a more detailed scan of your car. The mechanic will use the codes as a starting point in determining the true cause of the problem.

6. Take note if the light on the console goes out before you can take the car in for service. This indicates that the problem has been resolved. 7. Learn more on how to diagnose car problems with an OBD2 Read more: How to Diagnose Car Problems With an OBD2
