Dr. Prius is an application designed to assist professional Toyota/Lexus hybrid repair shops and vehicle owners in assessing high-voltage battery health. It transforms your mobile device into professional diagnostic equipment, typically costing thousands of dollars, and is trusted by over 439 professional repair shops globally.

Dr. Prius performs tests and provides access to all relevant battery data, enabling quick problem identification with a simple touch on your smartphone screen. Avoid falling victim to a failing battery—test it and print a certificate to verify the battery system's health.

This application requires an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Many low-cost clone ELM327 adapters will not function due to an inability to switch between vehicle ECUs. Visit http://PriusApp.com/obd.html for details, or email us with any adapter compatibility questions. Using a WiFi OBD2 adapter is generally not recommended due to potential internet connection interruptions.
