Wonder what exactly the 'check engine' light means? The folks at CarMD have developed a new gizmo that translates your cars diagnostic codes and tells you what they mean in plain English. Simply load the CarMD software on your PC, link the tester via the USB cable, then log on to the CarMD website to view the probable cause and potential fixes to put your car back in running order.

You can use the tester to monitor and maintain the health of your 1996 and newer car, light truck, minivan and/or SUV for the life of your vehicle. The red, yellow and green indicator lights help you instantly diagnose the health of your, your family's, even your neighbor's vehicles.

The handheld tester can read your vehicle's computer and upload that information to your PC via the CarMD website, allowing you to diagnose your vehicle's health quickly and easily. A green light means you're good to go. Yellow light or red light? You can run a diagnostic report to find out what's ailing your vehicle, likely repairs and estimated repair costs.Take your diagnostic report to your mechanic to help ensure they have located the source of your car's pain and are planning to send you a fair bill.
