CarMD Is Powerful and Easy To Use
CarMD uses the same sophisticated technology your mechanic uses, but was designed for everyone to use. It does not matter whether you know a lot about cars or don't have a clue.
With a simple scan of your vehicle you can:
- Find out why your check engine light is on
- Know what needs to be fixed and what it should cost before seeing a mechanic
- Save money by fixing simple problems yourself
- Learn if your vehicle will pass its emissions test
- And much more...
CarMD Generates Money Saving Reports
The real value of CarMD is the detailed vehicle health information you get. Each report gives you a cure with the most likely fix and estimated repair costs in your geographic area. All fix information comes from CarMD's network of thousands of ASE-Certified technicians giving you "real world" solutions. CarMD's database of solutions is a living, breathing system that started over 14 years ago. Think of it as hundreds of technicians working to give you a solution. The report even provides important Safety Recall notices for your vehicle.

CarMD® OBD2 Extension Cable

CarMD® OBD2 Extension Cable
CarMD's 22-inch (56 cm) extension cable adds convenience and comfort while testing from your vehicle's front seat. One end connects to your CarMD handheld device, while the other plugs into the vehicle's OBD2 port.
On some vehicles, CarMD may plug in upside down making it difficult to read the screen and its color-coded (green, yellow, red) Vehicle Health MonitorTM LEDs. It reduces the need to rely on the tool's audible beeps to confirm a good connection.
