Obd Mary

Introducing OBD Mary, the ultimate EOBD/OBD-2 car diagnostic scanner, gauge dashboard, and trip computer, designed to elevate your vehicle diagnostics and monitoring experience. With OBD Mary, not only can you read and clear OBD-2 Trouble Codes, but you can also perform comprehensive diagnostics for various vehicle ECUs such as ABS, SRS, Airbag, HVAC, and more. Our scanner supports a wide array of vehicle brands, including Acura, Alfa Romeo, Audi, BMW, Chevrolet, Ford, Honda, Hyundai, Mercedes-Benz, Nissan, Toyota, Volkswagen, Volvo, and many others, ensuring broad compatibility and utility.

To use OBD Mary, you will need an ELM327 Bluetooth or Wi-Fi adapter to connect to your vehicle. It's important to check all ECUs in your vehicle as some may contain critical data.
