Application Description

Dr. Prius is a sophisticated app designed to assist professional Toyota/Lexus hybrid repair shops and owners in monitoring the health of their High Voltage (HV) battery. By transforming your mobile device into a professional diagnostic tool, Dr. Prius offers an affordable alternative to expensive equipment, trusted by over 439 professional repair shops globally. With Dr. Prius, you can easily test your HV battery and generate a certificate to verify its health, ensuring you don't fall prey to a faulty battery.

To use Dr. Prius, you'll need an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Be cautious, as most cheap clone ELM327 devices may not work due to their inability to switch between your vehicle's ECUs. For detailed information on adapter compatibility, visit PriusApp.com/obd.html. We strongly recommend against using WiFi OBD2 adapters because of potential internet interruptions during connection.

1. Real-time battery monitoring with intuitive charts and data.
2. A life expectancy test using a proprietary algorithm to estimate the remaining life of your battery.
3. A comprehensive battery test to diagnose the entire battery system.
