Dr. Prius is an application designed to assist professional Toyota/Lexus hybrid repair shops and owners in evaluating the health of their high-voltage battery. It transforms your mobile device into professional diagnostic equipment, which typically costs thousands of dollars. Over 439 professional repair shops worldwide trust our tool.

Dr. Prius performs tests and provides access to all relevant battery data, helping you quickly identify issues with a simple tap on your smartphone screen. Don't fall victim to a failing battery. Test your battery and print a certificate to verify the health of the entire battery system.

This application requires an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Most inexpensive clone ELM327 adapters will not work due to their inability to switch between vehicle ECUs. For more details, please visit http://PriusApp.com/obd.html, or email us with any compatibility questions. Using a WiFi OBD2 adapter is generally not recommended due to potential internet connection interruptions.
