Home | What Does CarMD Test?
The CarMD tester monitors all of the systems throughout the vehicle that are related to on-board diagnostics. This translates into coverage of approximately 80 percent of the vehicle’s systems.
The CarMD device and website are meant to provide a basic overview of probable causes related to engine, electronic and emissions systems in your vehicle. This product should be used as a supplement to a regular automotive maintenance program, which also includes basic mechanical upkeep such as regularly checking your tire pressure, oil and fluids. *
