Dr. Prius

Dr. Prius is an essential tool for professional Toyota/Lexus hybrid repair shops and owners, designed to monitor and test the remaining life of your vehicle's High Voltage (HV) battery. With this app, you can transform your mobile device into a professional diagnostic tool, typically costing thousands of dollars. Trusted by over 439 professional repair shops worldwide, Dr. Prius offers a reliable solution to keep your hybrid's battery in top shape.

With a simple touch on your smartphone screen, Dr. Prius performs tests and provides access to all relevant battery information, enabling you to quickly identify any issues. Don't be a victim of a failing battery—test it and print a certificate to prove its health. To use this app, you'll need an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Please note that most cheap clone ELM327 devices won't work due to their inability to switch between ECUs. For more details on adapter compatibility, visit PriusApp.com/obd.html or email us at [email protected]. It's generally not recommended to use WiFi OBD2 adapters due to potential internet interruptions during the connection.
