Dr. Prius is an application designed for professional Toyota/Lexus hybrid repair shops and owners to evaluate the health of their high-voltage battery. It transforms your mobile device into professional diagnostic equipment that typically costs thousands of dollars. Trusted by over 439 professional repair shops worldwide.

Dr. Prius performs tests and provides access to all relevant battery data, helping you quickly identify issues with a simple screen touch. Avoid the risk of battery failure by testing your battery and printing a certificate to verify its health.

This app requires an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Most inexpensive ELM327 clones won't work due to their inability to switch between ECUs. Visit http://PriusApp.com/obd.html for details, or email us with compatibility questions. Using a WiFi OBD2 adapter is generally not recommended due to potential internet interruptions during connection.
