The CarMD device plugs into your car's OBD port and reads diagnostic information from the car's computer, immediately indicating the diagnostic status with a red-yellow-green light, and then downloading ALL of the computer information so that a more detailed analysis can be created after gathering code data from the web.
Since 1996, the federal government has mandated a standardized OBD port be placed on each foreign or domestic vehicle sold in the United States which allows simple testing of vehicle emissions diagnostics. The CarMD device works with all vehicles 1996 and newer, and also works with the even newer OBD2 cars.
After you plugin the CarMD into the OBD port (a video shows you where the port is located on various cars), codes are downloaded into the device and an initial assessment is made. Then, take the car to your computer and plug it in via a USB port, and the information is compared to a comprehensive database of codes on the internet and an easy-to-understand automotive diagnostic report is created, including estimated repair costs.
In the current economic climate, more people are choosing to buy used cars or keep their current vehicles instead of purchasing new ones, so we think that the CarMD device could be an essential tool, especially for someone shopping for a used vehicle, but also for anyone trying to maintain family cars and wanting to insure that repairs are made early and appropriately.
